Six Sigma Analyze Phase

Six Sigma aims to define the causes of defects, measure those defects, and analyze them so that they can be reduced.We will consider five specific types of analysis that will help to promote the goals of the project. These are source, process, data, resource, and communication analysis. Now we will see them in detail:

1. Source Analysis:

This is also called root cause analysis and attempts to find defects that are derived from the sources of information or work generation. After finding the root cause of the problem, attempts are made to resolve the problem before we expect to eliminate defects from the product.

THE THREE STEPS TO ROOT CAUSE ANALYSIS

  • The open step: During this phase of root cause analysis, the project team brainstorms all the possible explanations for current sigma performance.
  • The narrow step: During this phase, the project team narrows the list of possible explanations for current sigma performance.
  • The close step: During this phase, the project team validates the narrowed list of explanations that explain sigma performance.

2. Process Analysis:

Analyze the numbers to find out how well or poorly the processes are working, compared to what's possible and what the competition is doing.
Process analysis includes creating a more detailed process map and analyzing the more detailed map for where the greatest inefficiencies exist.
The source analysis is often difficult to distinguish from process analysis.The process refers to the precise movement of materials, information, or requests from one place to another.
