The benefits of a Free Six Sigma Black Belt Improve Phase test

If you haven’t heard about DMAIC projects probably you shouldn’t be reading this article, since we will review the necessary knowledge and skills for advancing to the title of Black Belt in Six Sigma. So you should first be informed on what are the origins of the Six Sigma concept, what is his purpose and the specialists involved.

We should first shed light upon the concept of Six Sigma. It originated in 1986 and was developed by Motorola. This method aimed to reduce errors and to help making things better and faster through a set of quality standards for daily work. Six Sigma originated as a set of practices designed to improve manufacturing processes and eliminate defects, but its application was subsequently extended to any problem within a company that needs to be solved for increasing its value. The Six Sigma approach has a very well-defined structure known as the DMAIC project methodology: Define, Measure, Analyze, Improve and Control, each following a defined sequence of steps and having a specific, quantified financial target. This business management strategy creates a special infrastructure of people within each company who are experts in the above-mentioned methods. The training for Lean Six Sigma is provided through the belt based training system, with the belt personnel consisting of White Belts, Yellow Belts, Green Belts, Black Belts and Master Black Belts. The Black Belts who are subject to this article are high on the hierarchy and they have the responsibility of leading problem-solving projects and coaching and coordinating projects teams.

As a Black Belt professional you are expected to explain Six Sigma philosophies and principles to your team, mentor your fellow colleagues in this field and assign roles and responsibilities for them. Also, as a Six Sigma Black Belt you will be given the trust to develop more complex projects within your organization. Therefore, you need to be sure you could handle all these responsibilities and the first step towards achieving this is to learn. It is very important that you give equal importance to all the phases of a project, beginning with the define phase and ending with the control. For each phase, you should prove your capacity to understand its purpose and the tools that can be used for attaining it. One of the phases you must train on is the improve phase that comes after the analyze phase and uses its outputs.  

Free Six Sigma Black Belt Improve Phase Test

The improve phase deals with some important topics, such as the design of experiments, waste elimination, cycle time reduction, theories of constraints, implementation and risk analysis. You should first be able to conduct different experiments, such as one factor experiments, two-level fractional factorial experiments and full factorial experiments. Concerning waste elimination, you must be familiar with the techniques for preventing or eliminating wastes. There are seven kinds of wastes that need to be eliminated in the view of the Six Sigma: defects, overproduction, transportation, inventory, overprocessing, waiting and motion. Furthermore, you need to be up-to-date with tools for reducing cycle time. Once you have made experiments and decided the necessary improvements to be made you should develop the optimal plan for implementing these changes. The last step in the improve phase of a DMAIC project is the risk analysis, where you can use a feasibility study, a SWOT analysis to identify strengths, weaknesses, opportunities and threats or other such tools.

If you want to be acknowledges as a professional Black Belt you must follow every step of the process and acquire as much expertise as you can. You must constantly improve your knowledge and give the proper importance to every detail of a project because you need to prove yourself able to cope with high-complexity and demanding projects.
