Benefits of a free Six Sigma Black Belt DOE test
For any manager working in the business environment the term „Six Sigma” should sound at least familiar. Although it is a relatively recent concept, the Six Sigma has gained appreciation for providing the systems and tools to solve problems in a professional and methodical manner. The Six Sigma is an innovative managerial concept firstly developed by Motorola in 1986, its purpose being to improve manufacturing processes and eliminate defects. However, 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.
If you are already certified as Green Belt and wish to upgrade to the more prestigious Black Belt title you should make serious efforts for training if you want to be able to pass the Six Sigma Black Belt exam. For achieving this, you must give equal importance to all topics of a DMAIC project, and the DOE is one of the essential topics you must cover. DOE stands for Design of Experiments and it is the first activity to be performed in the Improve phase of a DMAIC project. This means that output data resulted from the Analyze phase serves as input for the Improve phase that aims to find solutions based on the uncovered problems in the previous phases. The DOE is a methodical tool used in Six Sigma for validating the correlations between input and output variables. The name is suggestive for its purpose: to design efficient experiments that once conducted will generate relevant data so that they won’t need to be conducted again on behalf of errors in experimenting.
Implementing changes within a company might have unexpected and sometimes undesired effects so it is recommended to make further analysis for avoiding such situations. In most of the times it is the responsibility of a Black Belt to decide which project concept should be subject to the analysis. The difference between the DOE and other Six Sigma tools is that it only manipulates input variables with the purpose of studying outputs. The method uses many experimental concepts depending on the expectations of project owners. The alternatives at hand are the full factorial schemes, the fractional factorial models or the response surface designs. While the full factorial scheme determines the efficiency of every input or combination of inputs, the other two techniques use specific algorithms to minimize the frequency of variations that is crucial for achieving favorable results. The most extensive application of the DOE relates to projects with insufficient data. This tool can be used both in the analyze phase and in the improve phase. When it is used in the analyze phase its purpose is to validate possible errors in the process, while in the improve phase it is bound to evaluate whether the designed developments will give the optimal result. For being able to perform experiments you must have both basic knowledge of statistics and the components of an experiment, since you will need to understand the factors that need evaluation, their setting and the responses that must be measured. The Design of Experiments, when performed efficiently, reveals the sensitive areas in designs that affect yield. Professionals will consequently be able to fix the problems and improve performances.
