Types of analysis in the analytical phase of the DMAIC method (Part 1)

The Six Sigma DMAIC method (Identification, Measurement, Analysis, Improvement, Control) can be defined as a roadmap for problem solving and process improvement. The problem phase identifies the problem, the measurement phase collects data and uses it to measure performance. The third phase, that is, the analysis phase, focuses on identifying, statistical and statistical analysis the root cause from the data collected after the measurement phase.

The main steps taken during the analysis phase are:

• Define performance goals
• Identify the steps to add value / not add value
• Identify sources of variation
• Identify the root cause (s)

To do this effectively, different types of analysis are used. The following is a list of the different types of analysis performed during the analytical phase of the DMAIC method:

• Process map analysis
• Graphical analysis
• Statistical analysis

Process map analysis:

The Analysis phase begins with the detailed process map analysis. It is a visualization workflow planning and management tool. The main purpose of process map analysis is to improve efficiency. Process map analysis provides insight into a process, helps teams come up with different ideas for process improvement, increases team interaction, and provides process documentation. Process mapping for bottlenecks, repetitions and delays It also helps identify boundaries, authorities, and responsibilities in the process.

Benefits of process map analysis:

• Increased understanding of a process
• Analyze how a process can be improved
• Improve communication between individuals involved in the same process
• Provide process documentation
• Effective project planning.

Tools for process map analysis:

Brainstorm (the method used to develop many creative solutions to a problem, by participating in all members of the group to raise ideas focusing on that issue “freely” and “drama” paralysis ”).

• Plan-Do-Check-Act Cycle (PDCA cycle Plan-Do-Check-Act)
• FMEA (Failure and effect analysis)
• Fish bone diagram
• SIPOC diagram (tool used to identify the elements of a process improvement plan before starting work)
