Waste is the dead weight that does nothing but brings the project value down. It can be wasted time, resources, or efforts that never yield any results. Any waste in lean Six Sigma will result in lowering productivity levels and might as well lead to project failures. That is why every organization plans to reduce its overall wastage and increase project value too many folds. They appoint qualified professionals to study current company operations and create plans to eliminate or at least effectively reduce waste.
They hire somebody preferably with the lean Six Sigma certification, as they will be proficient with a comprehensive understanding of the techniques and strategies that can help reduce waste efficiently enough to improve overall company operations. If you are an organization looking for ways to eliminate waste, hiring qualified professionals with a comprehensive understanding of the 8 wastes downtime is crucial. On the other hand, if you are a candidate, taking up a certification course can be your first step toward a successful and promising career. Let us discuss the 8 wastes of lean Six Sigma for better clarity.
What are 8 Wastes in Lean Six Sigma
In lean manufacturing, you will find challenges depicted as wastes that reduce the chances of project success. Time and resources are the fundamental downtime lean waste, as it accounts for the significant loss in productivity levels. Additionally, if there are defects in a project, the team would have to spend more time, effort, and resources on it to resolve the issue before delivery. All of this together fall into the category of 6 sigma waste. The concern of every organization is to eliminate that waste to increase overall productivity.
Let’s see the 8 wastes in six sigma:
- Over Production
- Defects
- Waiting
- Transportation
- Unused Talent
- Inventory
- Motion
- Extra Processing
To start working on something, one has to understand the task well. Hence, to eliminate waste during a project, one has to know about the types of waste Six Sigma. Let us check these in details.
1. Over Production
Some organizations produce things even before their requirement pops up, wasting time and resources in manufacturing. Furthermore, some teams overestimate the requirements and manufacture unnecessarily large units of products. As a result, the demand doesn't meet the manufacturer's expectations, leading to overproduction. The goods produced are useless, so the resources and efforts they put into manufacturing also go waste. Some of the common reasons behind overproduction are:
- Zero strategies in manufacturing units
- Inaccurate forecast and demand expectations
- Unclear consumer requirements
- Not keeping track of production routines
These are the common causes of overproduction that makes up for a significant waste in a project.
2. Defects
Not paying enough attention to the flaws during the production process leads to multiple defects that only result in a flawed end product. No client or consumer would accept defective products, so it is clear that you have wasted all your time, effort, resources, and capital. Some of the common reasons behind defects are:
- Poor quality control
- Lack of clarity during requirement gathering
- Improper functioning of the machinery or tools involved
These and multiple other factors lead to increased defects in the end product, a significant type of waste.
3. Waiting
Waiting for resources or putting human efforts on hold is all about the waiting waste. You may not consider, but all this wait costs the company additional expenses, and it will reduce the project value significantly. In simple words, waiting is the opposite of overproduction, where the organization puts the project on hold and doesn’t have enough to offer to its clients. The reasons behind waiting are:
- Poor communication among teams
- Idle equipment which nobody needs
- Delayed setups or lack of control over the processes
Apart from this, the factor leading to waiting includes unplanned downtime.
4. Transportation
The operations happen at varied locations in the industries spread across a large area. Thus, there will be a lot of transportation of goods, accessories, and humans to complete a project. If the site gets designed by experts, at least units that have to work collaboratively stand nearby to reduce transportation expenses and time. However, if the design is poor, you would have to consider transportation as waste. The primary reason behind this waste is poor site design or lack of strategy while managing the unit.
5. Unused Talent
It is one of the most significant losses associated with not using the available talent efficiently. The management team doesn’t pay attention to how they can allot tasks to people considering who would do what to the best of their capability. For example, if you have an employee with a financial background, assigning inventory management tasks to them is a blunder! Thus, it is essential to divide the task smartly, ensuring no talent goes unnoticed and everyone contributes towards the project to the best of their abilities.
6. Inventory
Holding the raw materials and resources used for product manufacturing results in inventory waste. You will have to allocate space to things that are not required in the near future and will have to bear the storage expenses. Additionally, everything will go to waste if the product isn't used soon! All of it happens due to mismanagement and not keeping track of the production processes, and this wastage of resources, capital, and time leads to lower productivity levels.
7. Motion
To move people and things from one place to another will cost money. So, if your manufacturing site is far from the storage unit, consider the additional charges as waste. The more you want to move these things your total expense on the project will also increase. Another waste category in Six Sigma is the significant amount of time that goes into this process.
8. Extra Processing
To keep processing information unnecessarily is the eighth waste type in Six Sigma. It often happens when the communication between the teams is not efficient. However, it can also occur due to human error or delayed approvals by management. Whatever the reason is, extra processing is a waste that drastically impacts project success.
These are eight types of wastes that lead to downtime Six Sigma. It can affect productivity levels, increase project costs, and even lead to failure. Let us discuss a few lean waste examples for better clarity.
How to Endure Negligible Downtime
The most significant waste factor includes downtime in Six Sigma and lean waste. It might happen due to candidates sitting idle and not giving their best or one team waiting for the other to complete a connecting task and sitting idle till then. Companies try to find solutions to eliminate waste by replacing the dead weight with something more fruitful. Furthermore, they bring the necessary tools and techniques into the picture to improve the project’s potential by eliminating the waste factors. Simple things they do to ensure negligible downtime are:
- Ensuring that the company operations happen smoothly and seamlessly so that the teams working together do not have to waste time waiting.
- Giving relevant tasks to people, keeping their abilities or talents in mind to ensure no resource gets wasted when the project is in process.
- Eliminating the downtime that happens due to a shortage of resources or other factors. For example, people might have to wait till management starts the meeting or till the higher authorities provide them with the required resources.
- Organize the inventory and the administrative task, leaving no stone unturned in achieving zero downtime and maximum productivity levels.
There are multiple other strategies or proven techniques that every organization uses for Six sigma waste reduction. The question that might arise here is, what exactly happens if you do not remove waste or why is it necessary to remove them from your project? Let us dig deeper and discuss this in detail.
Why it is Important to Remove Wastes
Waste identification and elimination from a project are essential as they might lead to complete failure or lower the overall value significantly. Moreover, even if you complete the project successfully, the profitability will not be as fruitful as it can be if you do not pay attention to waste elimination.
It is not easy to remove every possibility of waste, but hiring qualified experts with Green Belt courses can prove fruitful. These experts can identify the issues or the waste types that reduce your project value. They analyze the current situation, identify triggers, and curate strategic plans to ensure project success. If your choice of experts is apt, you can rest assured that Six sigma waste elimination will never be an issue!

8 Wastes Examples
There are countless examples for each of the 8 types Six Sigma waste. We have categorized the real-life examples accordingly to help you understand them better.
1. Defects
Common defects you might face are misleading information on the charts or reports shared across the project team. Another example can be wrong labels on the containers or basically any other mistake that can lead to flawed actions.
2. Overproduction
Real-life examples of overproduction include printing unnecessary documents when you have the option to keep information on the computer system. Another option is to store the same information on multiple forms instead of segregating it into one.
3. Waiting
As the name suggests, waiting is when the client has to wait for the service delivery or if one team waits as the other sends information to start their work. Moreover, waiting is also when the team sits idle, waiting for the resources that the company has to provide.
4. Transportation
You can link it with moving assets unnecessarily from one place to another. It is also related to the event when one has to make too many mouse clicks on the website before getting the required information.
5. Inventory
Overstocking products even when you can do with much lesser quantity. Keeping unnecessary documents and files in the office cabinets is also an example of waste.
6. Unused Talent
Not assigning tasks as per talents is significant waste in an organization. Moreover, not organizing staff training to update the skills also leads to asset wastage.
7. Motion
Excessive staff movement to fetch things they require is a waste associated with time.
8. Extra Processing
Processing the same information over again is a waste of time, effort, and resources. Once you get satisfactory test results, move ahead and do not keep processing them.
These real-life scenarios would have given you an elaborate idea of what ‘waste’ refers to in any project. So, if you are a project manager or simply a person concerned with project efficiency, identify if you see any such waste around you and take necessary actions to eliminate its impact.
