Six sigma knowledge is very essential for those who are searching for jobs as a business analyst. This is the frequently asked business analyst interview question by interview panel.
- Identify the definition phase is used to fix the problem, which must decide. The term “voice of customer” is often used in Six Sigma. The voice of the customer used to understand that the problem lies. This may be an external customer or an internal customer, such as employees of the company in a particular business process is the stage that could be involved. While the definition of the problem are clear objectives of the project, he said. objectives should be clear what the best procedure, or what is “essential quality.”
Action – The action taken by the state defined the problem and measures key aspects of the process. The collection of data necessary to ensure that the results can be compared with the control phase in the exploitation phase and to demonstrate objectively that the process that the proposed improvements. These are the words “can not improve what you hear you can not measure.”
- Analyze the data analysis phase is retained in the measurement is analyzed to understand the cause and effect, and the result of analysis of causes. The equation y = f (x) is very popular in Six Sigma. He stressed that the name problem “y” is a function of “X” where “x” inputs or factors determining the outcome “y”. The analysis phase is the measure of all inputs that have a significant impact on the outcome of the process of detection.
- Improvement of phase improvement, the current process has been redesigned, the analysis is complete, the analysis phase. Ensure that records are in a process of the correct and in good condition for improving the outcomes of the process. In fact, the process can be anything. An investigation of the conditions to be used to develop a computer system. If it is found that the quality of inputs (requests) are in-al, the team can focus on an improved process for gathering requirements, which will lead to better results of the project. Under the new procedure is intended or should be tested before the completion of the original. The test results can be measured to ensure that the desired improvements.
Control – The control phase is an important step in the DMAIC. He stressed the need to constantly monitor the improvement process to ensure that the differences can be corrected with the desired results. Not opening phase of supervision, the benefits of several initiatives aimed at improving the process will reduce the time. The control phase can also be used to begin to explore new areas of improvement and the DMAIC process again.
