Read Time:1 Minute, 5 Second

The steps in the analyze phase are:

  1. Determine which factors impact the performance, i.e. X’s in Y=f(X)
  2. Organize the potential X’s
  3. Shortlist the key X’s
  4. Develop a data collection plan for the analysis
  5. Prove the key X’s for Y=f(X)

The possible X’s are determined by brainstorming. The potential X’s are organized using a cause-effect diagram or fishbone diagram. The potential causes are shortlisted by consulting the experts.

We need to develop a data collection plan because a sufficient number of data points have to be collected so that we can d further analysis such as regression. Inferential statistics and hypothesis testing are used to prove the X’s as major factors. At the end of the analysis phase, we have a list of proven X’s that were validated by data-driven analysis.

1.How to Use Cause-Effect Diagram?

It is a diagram o organize the list of causes which impact the effect.

2. Data Collection in Analyze Phase

Planning for data collection starts with the questions:

  • What is the hypothesis to be tested?
  • What type of hypothesis is to be tested?
  • How many data points are needed to draw the collection?
  • From whom, when and where should the data be collected?

Planning helps the team save time during the inferential statistics and hypothesis testing.
