Six Sigma Data Collection Requires Asking the Correct Questions

By Craig Calvin

The Six Sigma level is that of achievement of zero defects. The DMAIC methodology is popularly used by many organizations to bring about such changes effectively. In the Measure phase of Six Sigma, the relevant data regarding the product is collected. Depending upon this data, further analysis and improvements are made.

Collecting the Right Data- In the Measure phase, by asking questions to the customers, internal as well as external, the data is collected. This is where it becomes imperative that the right questions are asked by the Six Sigma team to understand the related matters correctly. Only when the question has been asked in the right manner will you get the right answer, which can then be used to bring about improvements in the organization.

The following are some tips for achieving the right data in the Six Sigma projects: 1. The number one thing to be sure of is that the people involved in the collection of data realize the importance of its accuracy and how it will be used. This will ensure there are no misunderstandings. 2. Consider using a third party to collect the data, which can eliminate any kind of bias. 3. Make sure to consider outside factors, such as location, shifts, machinery.

Having to repeat the data collection process because of an error is not a desirable action. Workers might not be able to spend more time on this process. It is crucial to ask a good question that is simple enough for them to understand and reply to. When using formats, such as questionnaires, it is ideal to design it in columns instead of rows, mimicking a spreadsheet. This enables comprehension.

A more cut and dry questionnaire is ideal. This will eliminate any misunderstandings, which will also eradicate any potential wrong answers because of unsurity. Running a trial run of the data collection would be a good idea, and would give you a chance to pick out potential questions that could create wrong answers.

In addition, if there is anything that stands out as potentially requiring additional attention, you can identify these problems before delivering results to a client. These tips are best kept in mind if you are concerned with ensuring optimal results. - 15246
