What is Six Sigma?

Six Sigma is the methodology for enhancing the output quality in a business process. It does this by identifying and removing the causes of the defects. This can be done using quality management methods that include statistical and empirical approaches. Bill Smith first released six Sigma and registered it as a trademark. 

But after ten years, when Jack Welch used it as a business strategy at General Electric, it became popular in the business world. Project Management Software approves and reviews the project performance according to the practices of Six Sigma.

What is Six Sigma in Project Management?

Six Sigma is the methodology utilized for finding and handling the weak points in the efficiency that restricts the efficiency or results. It helps you visualize how your service or product goes from the beginning stage to the final product. Before utilizing Six, Sigma in project management, we should ask ourselves the following questions:

  1. What is the goal of the project?
  2. Is it going to make the project more efficient?
  3. Is it to introduce new technology?

Along with the above questions, we have a few more considerations:

1) Eliminating waste, whether that can be wasted resources, time, or materials.

2) Reducing the variations or defects of the service or product

3) Defining the root cause of the problems

4) Using data more effectively to enhance productivity and efficiency

5) Increasing employee and customer satisfaction

6) Designing a new process or redesigning an inefficient process.

Using the Six Sigma methodology in project management is beneficial due to the following reasons:

1) Structuring the Team: Six Sigma methodology clears the organization from scratch. Several projects may fail due to organizational issues that can be reverted to the project's inception. Regardless of green belt or black belt team members, we can have strong and experienced leadership. 

2) Using DMADV and DMAIC as the project process: 

Project Management itself is a process. The steps we take to ensure the project's success must be enhanced. Following the DMAIC style of project evaluation can uncover the weak areas and spots for enhancement.

3) Measuring and Analyzing for finding the gaps

If you are struggling to find unexpected results or failures, you can use the scientific approach of Six Sigma. It will allow you to arrange your process effectively for discovering the gaps.

4) Relying on the data to get an exact picture

The approachable steps of Six Sigma will help you use the data to evaluate the areas for enhancement.

Characteristics of Good Six Sigma projects

As per the characteristics of a process or the result of the Six Sigma project, whether it is a promising project or not. A good six sigma project will have the following characteristics:

1) Generates High-Quality Products

In the Statistics field, Six Sigma means Standard Deviation. This tells the importance of the Six Sigma practices in statistical quality control. A good Six Sigma will build  a good quality products. If the products developed by the Six Sigma projects fulfill the specified standards, it indicates that the project was successful and promising.

2) Follows the Methodical Approach

For enhancing the quality o the output, we must use a systematic approach. So a Six Sigma project that utilizes the DMAIC control for enhancing the quality of the output is the best sigma project. The impact of this approach will be evident in the processes or products developed by those projects. Instead of the DMAIC method, the DMADV method can be used to get better outputs.

3) It is Fact-Based

The process of all the Six Sigma projects is either data-based or fact-based. Any project that utilizes systematic and statistical aspects is the best prototype of a Six Sigma project.

4) Customer-Oriented

One of the best principles of the Six Sigma practices is Customer-Oriented. Improving the standard and quality of the products are entirely based on customer demands and needs. A customer-oriented project is the best six sigma project.

5) Facilitates Teamwork

Teamwork is another crucial aspect of Six Sigma. It requires the cooperation of team members for an efficient process of improving and regulating product quality. If the team gratifies the project that operates in accord and has obtained enough training, the project is considered as the best project.

6) Goal-based

Apart from implementing the six sigma methodology in the project, we have to build and figure out the final goal. This involves the enterprise's objective and individual goals. Therefore, a goal-based project will be the best project.

The best and most efficient principles and approaches will give prominent results for the project. Thus, a project with the above properties is considered as the best sigma project.

How do we start a Six Sigma project?

While starting a Six Sigma project, we may face some difficulties:

1) Enterprise Barriers

To adopt the Six Sigma methodology, we have to deal with process experts and make them accept the new approach. Sometimes, we may not get the leadership support for the project, so we have to understand their difficulties and resolve them.

2) Handling the Barriers

We can handle the enterprise barriers using the following ways:

  • Creating the Sharing requirements

This is the reason to run the project. It should be coordinated with the enterprise vision. It must be in coordination with Demand, Demonstration, and Data.

  • Forming a Vision

The vision must be clear and coordinated with the vision of the stakeholders.

  • Generating the Commitment

We have to develop a strategy for winning the stakeholders' support. Through that strategy, first, we have to convince low-level management and then high-level management.

To resolve the above difficulties, the Six Sigma project utilizes the Six Sigma methodologies like DMADV, DMAIC, DFSS, Statistical tools, and Business Process Management. Working with the Six Sigma projects means complying with and planning the methods and values included in Six Sigma. So, planning is the beginning phase to start the Six Sigma project.

Go through the step-by-step approach of a Six Sigma project:

1) Build the Framework

In this phase, we should consider all the essential principles and aspects of Six Sigma. Determine the objective you have to get, the problem you require for solving, or the chance you want to continue. Next, we will concentrate on the factors holding the projects, like expenditure, scope, advantages, team members, timeline, etc. After handling these aspects, we can begin the project efficiently. 

2) Choose the Methodology

In Six Sigma, we can use multiple methodologies to do a good project. Some will use Lean Methodology, Focus Methodology, and Plan-Do-Check-Act principle in a Six Sigma project. The best Six Sigma project methodology or type will serve as a guideline to guide you through the journey to victory.

3) Start the Project

We must execute whatever we have planned quickly. When we spend too much time, planning, we may strike at the first phase itself. When we begin implementing things, several junctures will ebb and flow, and we have to deal with them.
