Bench is critical about Six Sigma and similar approaches, and thinks that these take long time. Bench also thinks that by the time perfection reached, the process becomes obsolete. Mark has a different outlook. He knows DMAIC is suitable sometimes, DMADV or DFSS is needed at other times. Mark also knows that other approaches exist and has a well thought out approach to problem solving.

The best answers for IoT security threats are provided by Shashank Parihar and Mohamed Asif. Both of them are winners for this question.

Q 213. It is common to see two aproaches in Hypothesis testing. These are mentioned below. Take a certain number of samples (whatever is feasible practically), and test the decided hypothesis. If the statistical significance is not proved, take some more samples. Keep increasing samples as long as possible and stop if significance is proved. This aproach keeps initial cost low. Decide the number of samples using a sample size calculation (considering alpha, beta, difference to be detected and hypothesized value etc.) and take a decision based on the outcome of hypothesis testing. This approach provides decision in one go. Which of the two approaches for Hypothesis testing will you select? Why? Note for website visitors - Two questions are asked every week on this platform.

Excellent response by Mohamed Asif and he is the winner. Also commendable is the response by Bhavin. I am sure if Bhavin was able to spend more time, he would hae built up on his answer.

Someone asked me how Lean Six Sigma will be put to use in a background check process. Here is the sequence that one may like to follow to identify and complete a project - Identify the biggest business challenges in Background Verification sequences. This could be in Education, Employment or Criminal. Let us say, that the challenge is fake certificates for qualification or employment. Once the biggest challenge area is identified, we will focus on the process. Which sequence is creating a bigger challenge? Is it verification through centralized database or through email verification or field verification? Let us say, the process to be worked upon is the email based verification process. We can now get into Define phase of the Lean Six Sigma Green Belt project. Our problem, let us say, is defined as - Poor response rates in email based employment verification from previous employers of a candidate. The Measure phase will look into our process flow along with past trends and whether our response rate data is reliable. We use certain techniaues for these objectives. The Analyze phase will focus upon finding the root cause of the problem. There can be several reasons why response rate is poor. Some of them are controllable, others are not. We need to finalize our list of prioritized causes using some techniques. Improve phase will require finding solution for the cause verified in Analyze phase. This will be followed by Control phase where we need to ensure that the improved process with better response rate is managed consistently in future. In the background check processes, there are mulstiple areas worth exploring with DMAIC projects. Some examples are - Improving fake certificate identification ability. Improve criminal verification processes through courts and police stations. Improve reliability of social media scanning for objectionable behaviour. Enhance accuracy of educational qualification checks. Improve knowledge base for enhanced results in employment verfication processes. Hope this helps.
