3 main types of Search Engine Optimization

Here are three common types of Search Engine Optimization used to improve website visibility and rankings. We will discuss these different types in further detail in the upcoming chapters of our guide.

1. On-site

This type focuses on optimizing your website’s content and structure to make it more appealing to search engines. 

On-site SEO involves techniques such as:

• Keyword research.
• Optimizing meta tags (title tags and meta descriptions).
• Creating high-quality and relevant content.
• Using proper heading tags (H1, H2, H3).
• Optimizing images with alt tags.
• Improving the overall user experience on your site. 

On-page SEO is essential for ensuring that search engines understand what your website is about and rank it higher in search results.

2. Technical

This type deals with the technical aspects of your website that affect its search engine visibility and crawling. Technical SEO ensures that search engines can easily access, crawl, and index your website’s pages. 

Technical SEO involves:

• Optimizing website speed and performance.
• Ensuring proper website structure and navigation.
• Using sitemaps to help search engines understand your site’s layout.
• Implementing structured data markup for rich snippets in search results.
• Optimizing for mobile devices.
• Resolving any technical issues that may hinder search engine crawling or indexing.

Technical SEO helps improve the overall user experience. It makes it easier for search engines to understand and rank your website.

3. Off-site

Unlike on-page SEO, this type is all about activities outside your website that still impact its search engine rankings. The main focus here is building high-quality backlinks from other websites to your own.

Backlinks act as “votes of confidence” for search engines, indicating that your website is trustworthy and authoritative. Off-page SEO involves social media marketing, influencer outreach, and online reputation management. These efforts help increase your website’s visibility, credibility, and overall online presence.

Creating a content strategy in 7 steps

Now that you understand the key elements of a good content strategy, it’s time to create one for your content marketing goals. We have listed seven steps below to guide you through creating your content.

1. Define your goals

Start by determining what you want to achieve with your content strategy. Are you aiming to increase brand awareness, generate leads, drive website traffic, or educate your audience? Clearly defining your goals will help guide your content creation efforts.

What you can do next is to rank each goal from the most important to the least important. By prioritizing, you can identify which plans require immediate attention and which can be dealt with later. It will also assist you in figuring out the resources needed for each goal as you move forward with your strategy.

2. Conduct a persona research

The previous section emphasizes the importance of having an audience persona in your content strategy. You must know your target’s age, interests, problems, and what they like. This knowledge helps you create content that connects with them better.

After you collect this information, you should look at the data to see if there are any common groups among your audience. These groups may have similar traits or interests.

It’s essential to revisit and study your audience regularly. This way, you can see if anything has changed and make sure you keep growing your audience. Also, looking closely at your current customers can help you improve your understanding of your target audience.

3. Do a content audit

Before you start creating new content, assessing your existing content through a content audit is important. It means checking how well your current content is doing. You can look at how many people interact with it, how many visitors it brings to your website, and how many people act after seeing it.

Conducting a content audit helps you understand the performance of your current content and reveals any gaps that require new ideas to fill them. You might discover that you can repurpose some of your old content, which means using it again fresh. Repurposed content allows you to make the most out of your content on different platforms and reach a larger audience.

4. Choose the content type and format

When creating a content strategy, choosing the right types of content that match your goals and connect with your intended audience is important. Different options exist, including blog posts, videos, infographics, podcasts, and social media content. Consider the format that best delivers your content and effectively captures your audience’s interest.

5. Define key messages

Here is the part where you consider the brand story of your overall campaign. You must decide on the main messages you want to share with your audience through your content. These messages should match your brand’s values and be something your target audience can relate to. Creating a consistent and compelling messaging strategy makes your content feel connected and well-put together.

For example, if you’re using different platforms like social media, blogs, or videos, ensure your messages remain consistent across all of them. Consistency will help your audience recognize your brand easily and understand what you stand for. Keep your language simple and easy to understand so everyone can understand your message.

6. Content creation and publication

Once you have set your goals, researched your target audience, audited your existing content, and defined your key messages, it’s time to start creating your content. 

Developing a content calendar will help you stay organized and plan when to create and publish your content. Ensure to produce high-quality content relevant to your audience consistently and adds value. It’s important to ensure that your content aligns with your overall strategy.

7. Measure and analyze

Creating content doesn’t end once you publish it. After publishing, checking how well your content matches your goals regularly is important. This process involves using the metrics you established in your content strategy to assess whether your content is helping you achieve your objectives. 

Keep an eye on metrics like engagement, reach, conversions, and feedback from your audience. Analyze this data to understand what’s working and what needs improvement. Take this feedback into account to make your content strategy even better.

5 Tips for creating quality content

Even with a well-defined content strategy, your content may not connect with your customers as effectively as you’d hoped. To produce higher-quality content, consider the following five tips:

1. Know your audience

Again, we emphasize understanding your customers well. Take the time to know who they are, what they like, and what they are interested in. By doing so, you can tailor your content specifically to their preferences, needs, and challenges.

A personalized approach ensures your content speaks directly to your audience and addresses their unique concerns. When your content resonates with your audience and provides valuable information, insights, or solutions, they are more likely to engage with it and find it helpful.

2. Employ storytelling tactics

Storytelling is a powerful strategy in content marketing that many marketers find effective. A whopping 62% of B2B marketers consider storytelling to be a valuable tactic in their content marketing efforts.

So, what exactly is storytelling in content marketing? It involves using narrative journalism and traditional storytelling techniques to captivate and persuade your audience. The goal is to create a connection by sharing compelling stories that evoke emotions. These stories follow a familiar structure, with characters, conflict, and a sense of progression.

By incorporating storytelling into their marketing approach, brands can forge strong and meaningful relationships with potential customers and existing clients. This method allows brands to go beyond simple promotion and engage with their audience on a deeper level. When done right, storytelling can leave a lasting impact and inspire trust and loyalty in your brand.

3. Create unique and original content

It’s fine to reuse content, but remember this: we come across more than 5,000 brand messages daily, yet we only notice about 86, and only 12 leave a lasting impression.

So, instead of copying what others have said, try to offer something new and exciting. Come up with fresh ideas, angles, and approaches that are unexplored. Give your audience unique insights and solutions that are valuable. 

This way, you can stand out from others in your field and catch your readers’ attention. Remember, the key is adding value and making your content different from the rest.

4. Use conversational tone

When creating content, writing in a friendly and approachable way is important. Imagine you’re having a casual conversation with your audience. 

Your writing should be simple, clear, and easy to understand. Avoid using complicated jargon or technical terms that might make your readers feel left out or confused. 

Instead, aim to connect with your audience using relatable language they can easily grasp. Adopting a conversational tone can build a stronger connection with your readers and make your content more enjoyable and accessible to a wider audience.

5. Incorporate multimedia

Research shows that about 65% of people learn better through visual content. If you want to grab your audience’s attention and keep them interested, add different media types to your content. Pictures, videos, infographics, and interactive elements can boost your content’s appeal.

For instance, using images can help show your ideas visually, making it easier for people to understand what you’re talking about. Videos can bring your content to life, allowing you to demonstrate things, share stories, or explain complex topics more effectively.

Including these visual elements make your content look better and more enjoyable and memorable for your readers. It’s a great way to cater to different learning styles and preferences, making your content more accessible to a broader audience.

Summary

In today’s digital world, content marketing is crucial. It involves regularly creating and sharing valuable content to educate, entertain, and engage your target audience. Doing so can build trust and establish strong relationships with your customers.

Having a well-planned content marketing strategy is crucial for creating effective content. A content marketing strategy serves as a roadmap for your goals. It enables you to measure your success and improve over time.

In the next chapter of this guide, we’ll explore the topic of search engine optimization (SEO) and how it complements digital marketing as a whole. In the meantime, be sure to implement the strategies and best practices we’ve discussed in this article to ensure the success of your content marketing.

Poka-yoke is a vital part of Jidoka in the House of Lean Production. Its main goal is to prevent errors and defects. The manufacturing industry utilizes Poka-yoke as a standardized work technique.

The main idea behind Poka-yoke is to stop errors and defects before they happen. Using Poka-yoke has proven to be highly effective in improving production efficiency in manufacturing. Now, let’s explore the definitions, benefits, and examples of Poka-yoke:

What is Poka-yoke?

Poka-yoke is a concept from Japan. Shigeo Shingo coined the term, and it’s all about stopping mistakes and ensuring products are perfect without any problems.

The concept helps find potential defects early on by preventing different errors during production. Here are some common mistakes that often happen in manufacturing:

• Steps are missing in the process.
• The process has faults.
• Incorrectly installed workpiece
• A piece is missing.
• Using the wrong parts. 
• The workpiece is processed incorrectly.
• Incorrect machine operation.
• Errors in adjustments.
• Incorrectly installed equipment.
• The tools and jigs are not well prepared.

Poka-yoke uses machines or methods to help spot mistakes quickly. Its main goal is to ensure the production process doesn’t progress unless everything is correct.

Read more: Lean Manufacturing: Definition & 3 Benefits

Two types of Poka-yoke actions

When it detects an error, poka-yoke takes two types of actions: turning off the engine or giving a warning. Here’s the explanation:

Shutdown

Shutting down the engine is the most potent action of Poka yoke. Here are some examples:

• The drilling operation stops when the light sensor fails to detect the required number of holes in the workpiece.
• The machine refuses to start if the workpiece is not positioned correctly. The on switch sends a weak electric current to the reference pin, and the engine only starts when it actively contacts each pin.

The full-work system is another way of shutting down a process. In this system, a supplier stops providing materials to the next stage when it has reached its maximum capacity. The system operates at total capacity when it achieves the desired number of parts.

Warning

The Poka yoke warning system sends out an alert when something goes wrong. It does this by making a buzzer or light go off. A well-known example of this is the andon board used by Toyota. It lets the group leader know when there’s a problem by showing the process number, playing music, or sometimes both.

In Toyota’s case, team members activate the andon by pulling a cable along the production line. The line keeps moving until it reaches a specific spot. Since each step in the process has its own fixed location, team members can finish at least one cycle of work. Stopping the line during an operation reduces the chances of making mistakes.

Three detection methods in Poka-yoke

Poka-yoke detects deviations in the workpiece or work method through the following ways:

Workpiece deviations

This method employs sensing devices to identify product weight, dimensions, or shape abnormalities. Here are some examples:

• Weight: Establish a standard weight and utilize a balance to weigh each product. 
• Dimensions: Standardize thickness, inside and outside diameters, and employ limit switches, stoppers, jigs, photoelectric eyes, and similar tools to detect deviations. 
• Shapes: Establish standard angles, number and position of holes, curvature, and detect deviations using limit switches, tracking pins, or similar detectors.

Work method deviations

This Poka-yoke method uses sensors to find mistakes in everyday actions. For example, a counter actively tracks the number of weld points on the workpiece. The clamps stay locked until reaching the correct number of weld points. This way, the work arrangement ensures that the next step can’t happen until the completion of the previous phase.

Deviations from fixed values

Counters play a crucial role in this scenario. They offer valuable utility, such as:

• You can utilize the limit switch to count the holes drilled in the workpiece.
• When you reach a specific count, you can switch the weld tips. The counter actively halts the welder once achieving the desired count. It remains inactive until you install a new weld tip.

Two types of sensors in Poka-yoke

Sensor technology constantly evolves, particularly in Poka yoke. In this context, we can classify sensors into two categories: contact sensors and non-contact sensors. Now, let’s delve into a more detailed explanation:

Contact sensors

The most common types of contact sensors are:

• Limit switches and micro switches: These sensors detect the presence of workpieces, prints, or tools. They are inexpensive and durable, making them suitable for various applications.
• Differential transformer: This sensor detects changes in the magnetic field depending on the level of contact with the workpiece.
• Touch switch: A gentle touch on the antenna activates it, allowing it to detect the presence, size, or damage of an object.

Non-contact sensors

The device can detect interruptions in the light beam, nearby solid objects, metal tracks, fibers, color, ultraviolet light, infrared light, counting errors, electron beam, size, pressure, temperature, electric current changes, and vibration. Here are some commonly used devices:

• Photoelectric device: This device is often used as a light screen to make sure the machine area is clean before using it. It can also measure actions, detect falling objects, and determine the size of workpieces.
• Metal parts detector: This device counts installed screws, checks for any removal of parts from the press, and ensures the guard is closed.
• Temperature: Thermometers and thermocouples detect changes in temperature for molds, motors, and curing ovens.
• Pressure: The pressure gauge can find blockages in pipes and detect excessive force in the machine.
• Current fluctuation: This is commonly used in spot welding to check for secondary currents that could weaken the strength of the weld.

Poka-yoke implementation strategies

There are two key indicators to ensure effective Poka-yoke implementation:

• Poka yoke must check 100% of items.
• Poka yoke must provide immediate feedback for countermeasures.

Implementing Poka yoke is straightforward and logical. Here are some steps for you to follow:

1. Identify company operations or work processes.
2. Analyze the causes of failures using the 5-whys method.
3. Determine the most suitable Poka-yoke method.
4. Test the chosen plan and evaluate the results.
5. Train operators, assess performance, and measure the success of the implemented Poka-yoke.

Poka-yoke implementation examples

In the automotive and consumer product industries, the pictures below demonstrate the application of Poka yoke. The floor shop team members are the ones who came up with most of the Poka-yoke ideas.

The car manufacturing industry faces challenges when loading cars into freight cars. Loading the car into the carrier proves difficult due to inappropriate height. Therefore, we need a method to prevent damage and ensure safety during car transportation.

To fix these problems, we implement Poka yoke in the following ways:

• We cut the wood to the right length and labeled and color code it.
• We attach the chain to the wood and position the house.
• We updated the standardized work to include a check for level.

Previously, detecting unfilled boxes in the consumer product industry posed a challenge for companies. Occasionally, boxes would remain unfilled due to machine errors, yet they were still closed and sent for shipment.

To address this issue, companies employ Poka yoke through the following measures:

• They install pedestal fans near the conveyors.
• They blow off unfilled boxes from the conveyor.

Summary

Poka-yoke is a manufacturing method that prevents defects and errors in production. It involves two actions: stopping the machine and providing a warning in case of a mistake. Poka-yoke is commonly found in manufacturing companies that heavily rely on devices.

Having understood the concept of Poka yoke, the next chapter will discuss involvement, the core of the House of Lean Production.

Jidoka is an integral part of Lean Production, just like the Just-in-Time (JIT) system we discussed earlier. While JIT focuses on product quality, Jidoka ensures quality is built right from the beginning. Without Jidoka, the Lean system could become imbalanced and fall apart.

Jidoka operates on these three fundamental principles:

1. Not accepting defects.
2. Avoiding the production of faulty products.
3. Stopping defects from passing on to the next stage.

Let’s look closely at Jidoka, including its meaning, why it’s essential, and how organizations can apply it in practice.

What is Jidoka?

Jidoka comes from the Japanese term “ji-do-ka,” comprising three Chinese characters. Ji represents workers who must stop the production line when they find a mistake and produce a faulty product. Do mean motion or work, and Ka indicates the suffix “-ation.”

Jidoka combines automation and human intelligence, allowing skilled workers and machines to find problems and take appropriate actions to fix them quickly.

Jidoka follows four essential rules to make sure that products are perfect:

• Find anything abnormal.
• Stop the work.
• Fix problems right away.
• Investigate and solve the main reasons behind the issues through careful analysis.

Jidoka strengthens the production process by continuously enhancing three key aspects:

• Processing ability.
• Detection (containment) to swiftly identify defects and take immediate action.
• Input (feedback) for implementing prompt countermeasures.

In the past, people might not have fully understood the revolutionary nature of Jidoka as an approach to quality management.

History of Jidoka

Sakichi Toyoda, the founder of Toyota, developed the Jidoka concept. In 1902, he made a clever loom that would stop automatically if a thread broke. This invention transformed the industry by allowing one person to handle many looms.

Sakichi’s invention had significant advantages. It reduced mistakes, cut waiting times, and improved productivity. He also suggested it was okay to pause production to find out why defects were happening.

Expanding on Sakichi’s ideas, Shigeo Shingo took the Jidoka concept further. He aimed for “zero defects” and introduced the idea of Poka-yoke. Shingo also developed source inspection to support Poka-yoke. He even showed that it was possible to inspect everything during production without spending too much money.

Why use Jidoka?

The high defect rate leads to frequent line stoppages, hindering flow and pull. When this happens, it causes damage to spare parts, leads to wait times longer, and increases production costs.

Shingo’s statement holds regarding humans and their propensity for making mistakes. Data from US military and aerospace programs have confirmed that humans often emerge as the least reliable component in complex systems.

The figure below illustrates the typical error rates associated with different human tasks. The left side of the scale denotes the highest error rate, while the right side represents the lowest human error rate.

Source: Dennis, P. (2017). Lean production simplified; Human error rates. (Courtesy of Lean Pathways Inc., Copyright 2014.).

Even extensively trained military personnel exhibit an error rate of approximately 20% during simulated martial law scenarios. The optimal performance level achievable by humans is one error for every 10,000 attempts, equivalent to 100 parts per million.

Improving worker reliability in production

Based on the data we mentioned earlier about human error rates, it’s clear that we can’t eliminate mistakes made by people in production. So, we need to use different methods to ensure workers are dependable. We discussed these methods in the previous chapter, such as standardized work, visual management, and 5S.

In addition to these methods, Jidoka also uses other techniques to improve worker reliability. Two of these techniques are called Poka-yoke and the inspection system. Here’s an explanation of each:

Poka-yoke

Poka-yoke means using a simple and cheap device to catch mistakes before they happen or stop them from causing damage.

A good poka-yoke should have these qualities:

• It’s easy to use and doesn’t need much maintenance.
• You can trust it to work well.
• It doesn’t cost a lot.
• The design fits its usage location.

The people working on the shop floor usually have the best poka-yoke ideas because they are actively involved in the production process.

Zone inspection and control system

Every level of management, starting from the team leader and going up to the supervisor and plant manager, should consider zone control. Let’s take the team leader zone as an example, which includes the team and its work area. The upstream and downstream team zones represent the supplier and customer, respectively.

This way of thinking promotes the development of duplicate controls, which are crucial in reliability engineering. Additionally, Jidoka employs an inspection system to ensure zero defects. Here are some of the inspection systems used in Jidoka:

Judgment inspections – finding defects

The purpose of judgment inspections is to prevent defects from reaching the customer or other processes. A different department usually performs these inspections after completing a task. Finding the cause of the problem or providing feedback to those responsible for the mistake is not a significant focus during these inspections. Instead, they focus on determining whether something is good or not.

Informative inspections – reduce defects

Informative inspections are all about finding problems, not mistakes, and giving feedback to fix them. They often use statistical tools like sampling protocols and Statistical Process Control (SPC).

Informative inspections are usually better than appraisal inspections, but sometimes there’s a delay in giving feedback and taking corrective action. The most useful informative reviews involve doing self-checks or checking relevant factors one after another.

U-shaped cells help with self-checking by placing the starting and ending processes next to each other. In each check, the following procedures look for defects and give feedback. These repeated checks work best when they cover all the items. The assembly line is a good fit for this kind of inspection.

Source inspections – preventing defects

Source inspections are inspection methods that actively search for faults that can cause defects and give prompt feedback to the source. We can categorize source inspections into two types: vertical inspections and horizontal inspections. Let’s take a closer look at each type:

• Vertical source inspections

To inspect this source type, search upstream for the root cause. For example, if there’s a water leak in the assembly, it may be because the paint shop didn’t apply the sealant properly.

Companies can quickly identify and address common problems using a standardized problem-solving approach and implementing a solid feedback loop. This feedback loop operates upstream and downstream and is vital for improving process capability and containment.

• Horizontal source inspections

In these inspections, we actively search for the root causes of problems within the department. For instance, the lack of techniques to ensure the installation of all required parts often leads to defects and loss in assembly shops.

Toyota actively encourages supervisors in each department to establish feedback loops. These feedback loops enable supervisors to address and correct any defects that arise promptly. They want every supervisor to adopt a mindset similar to that of a small business owner, considering suppliers and customers when making decisions.

Jidoka implementation strategies

To keep improving quality, you need a long-term plan for Jidoka. Here are some essential things to do:

• Measure how well each process works.
• Involve your team members and get them engaged.
• Make sure your team members have the knowledge they need.
• Use Pok-yoke to avoid mistakes.
• Train your team members appropriately.
• Clarify the roles of team members, supervisors, managers, and executives.
• Connect Jidoka with other methods like 5S, standardized work, and TPM.
• Communicate and promote Jidoka effectively.

By doing these things, you can keep using Jidoka successfully. Setting yearly goals and having a long-term vision for Jidoka is also helpful.

Annual jidoka strategy and goals

Include Jidoka in your overall Lean manufacturing plan. When implementing Jidoka, make sure to address the questions mentioned earlier and also consider the following points:

• Promotion & communication
• Provide training
• Measure & report

Set annual goals for the following:

• Number or percentage of processes that achieve a high rating.
• The number of Poka-yokes, Kaizen, suggestions, and similar improvements applied.
• Percentage of team members trained in Jidoka.

Percentage of team members participating in Jidoka activities.

Long term vision

Systems need to foster improvement to maintain jidoka. Start by assessing the company’s process capability level. You can determine the status by assigning scores and ratings to each process.

Ensure the scoring system is straightforward and doesn’t require complex statistical methods. Any team member should be able to evaluate a process and develop improvement ideas. Moreover, the system should offer clear guidance on progressing from one level to the next.

Example of a jidoka implementation

idoka, a concept utilized by Toyota, involves the famous andon process. This process encourages workers to halt production when they identify a significant problem immediately. Jidoka consists of two key elements:

• Direct communication between the supplier and customer.
• Embedded signals that indicate whether the situation is okay or not okay.

This process allows us to:

1. Convert customer needs into agreed-upon actions.
2. Display these actions on a board that compares targets with actual results using Red/Green scoring.
3. Conduct daily team meetings to discuss areas of concern and implement preventive measures.

Machines are superior to humans in detecting defects and halting processes. However, humans excel in problem-solving, making them better suited for Jidoka implementation.

Value Stream Mapping (VSM) supports the formation of Just-in-Time, as explained in the previous chapter. By implementing VSM, you can visualize, analyze, and improve all steps in product delivery.

In today’s saturated market conditions, it’s challenging to convince customers. Therefore, it is crucial to provide the value they need.

VSM is a strategy to enhance excellence and create the value customers seek. Let’s dive into the definition, process, and objectives of Value Stream Mapping.

What is Value Stream Mapping?

Value Stream Mapping (VSM) is a helpful tool for understanding your company’s current state and finding ways to improve. It shows you a detailed picture of every step in your work process, from getting supplies to delivering products or services to customers.

VSM covers all the essential steps to provide value, giving customers what they want to pay for. For example, a software company’s value comes from its software solution and its features.

It’s worth noting that not all work processes directly give value to customers. Some procedures, like quality control, don’t require customers to pay extra. However, without quality control, the product or service’s quality would suffer, and it wouldn’t match what customers want. 

So, even though it doesn’t directly bring in money, quality control helps ensure that the final product or service has the value customers expect.

A practical example of VSM implementation

Various industries like banking, healthcare, and insurance implement VSM. The symbols depicted in the figure below represent the components of VSM.

St. Clair Pallet, a company that makes business pallets, uses these symbols to show how they work. They cut, shape, and put together different kinds of wood.

Currently, the manual scheduling of production is conducted by the production manager for each process, relying on perceived daily priorities. The schedule undergoes frequent changes, represented by the dotted lines. Lead times vary between 12 to 15 days, and approximately 10% of orders are not delivered on time. 

Workers are compensated based on the work completed and strive to work as quickly as possible. Assembly cycle times are inconsistent, ranging from 80 to 120 seconds. Inventories are high in both the wood yard and between each process. The time required for equipment changeover is 30 minutes at the multisaw and 20 minutes at the notching machine. 

Waiting times at each process are significant due to shortages of small parts, machine downtime, and changeovers. The “spiky clouds” indicate potential areas for improvement (kaizen opportunities) and serve as the foundation for our future-state map

The picture below shows how things are now, called the current-state map. Based on the day’s priority, the production manager plans the work for each step by hand. The plan often changes a lot (shown by dotted lines). It takes 12 to 15 days to finish an order, and about 10% of orders are late.

Machine downtime and changeover cause lead times in each process. The “spikes” in the future-state map (shown in the figure above) indicate Kaizen opportunities. Here are some planned improvements:

• Implement type A pull system and set Takt time at around 68 seconds.
• Create a cell with two operators by combining multi-saw and notching machines.
• Utilize Kanban to restock items recalled from each store.
• Delegate daily scheduling to the production supervisor, freeing up manager time for Kaizen.

We need to do several Kaizen activities to support our desired future goals. These activities include:

• Making the assembly process more stable by distributing the workload better for two people and ensuring the time to switch between different assembly tasks is less than five minutes.
• Adjusting the operation of the saw machine so that two operators can finish the task in just 35 seconds. We also aim to decrease the time switching between different setups to less than five minutes for each machine.
• Implementing visual management and 5S in each store is necessary to achieve the following benefits:
  • Reduce lead time to three days.
  • Decrease loop yard inventory from 60 days to 10 days.
  • Cut work-in-progress inventory from eight days to two days.
  • Minimize finished goods inventory from five days to one day.
  • Boost productivity by 43% by reducing labor from seven to four without yield loss. Transfer the operators who are released accordingly.

Purpose and benefits of Value Stream Mapping

The main goal of Value Stream Mapping is to find ways to improve processes by visually showing the steps that add value and those that don’t. It involves analyzing each step in the workflow to see how it benefits the customer.

This analysis allows for a thorough examination of processes, giving clear insights into areas that need changes to improve overall efficiency.

Value Stream Mapping offers several significant benefits:

• It helps companies identify wasteful activities by eliminating unnecessary steps.
• Provides a clear view of the work process, showing the difference between steps that add value and those that don’t. It also indicates how long work items take to move through the process.
• Highlights the current workflow and focuses attention on future improvements.

Mapping Value Stream with Kanban in 4 Steps

Kanban is a highly dependable tool for Value Stream Mapping. It offers an intuitive user experience and facilitates easy modifications. To begin mapping your Value Stream with Kanban, you only need two essential elements: a Kanban board and Kanban cards for all team tasks. Now, let’s dive into the steps you can follow to start with Kanban Value Stream Mapping.

1. Choose a Kanban board

If you’re new to workflow visualization, start small. Begin with a single team or department. Ensure you select the most convenient method to map out your Kanban workflow—whether it’s a physical board or Kanban software.

2. Setting VSM goals & expectations

Gather the team and communicate the goals of the Value Stream Mapping. Kindly specify your objectives for implementing it.

3. Visualize the main stages of your workflow

Visualize your process together by default. A Kanban board includes three work item states: Requested, In-progress, and Done. Here’s an example of a Kanban board visualization:

4. Perform Value Stream Mapping analysis

Ensure you select a variety of performance metrics to monitor when implementing streamlined work processes. Some of the essential Key Performance Indicators (KPIs) to consider in your workflow are as follows:

• Compare the lead time to your task cycle time.
• Assess your system throughput.
• Keep track of the total Work-in-Progress (WIP).

To optimize work efficiency, it is crucial for the lead time and cycle time to align with each other closely.

To maximize throughput, prioritize maintaining a high level without compromising the quality of customer value.

Work-in-Progress (WIP) is a crucial indicator in Lean Manufacturing and Kanban. The greater the WIP, the more waiting time will accumulate. Therefore, limit the number of tasks your team can handle simultaneously and adjust workflow data accordingly.

Regularly monitor these key performance indicators (KPIs) and be open to experimenting with the addition or elimination of process steps and advancing your workflow.

Summary

Value Stream Mapping is a tool used to help visualize in detail all steps in the work process from supplier to customer. VSM aims to improve operations by visualizing value-adding and waste steps. In its implementation, VSM is closely related to Kanban.

Once you grasp the concept of VSM, the next chapter will focus on Jidoka. Jidoka is another critical element of the House of Lean Production.
