Getting started with the analysis of a process often feels like an insurmountable task. The following will help by breaking the analysis into ten small steps. These 10 steps are how you can analyze any process.
- Define and name the process. It sounds a little simple, but what process are you going to analyze?
- Determine which performance measures are important for the process and its customers.
- Map the process steps. A SIPOC process map is a good start.
- Collect enough performance measure data to set a baseline. Usually that is 20 to 25 data points plotted on a Process Control Chart.
- Conduct a Process Classification Cause and Effect for each process step in the SIPOC from the beginning to the end. Identify the potential variation contributors.
- Apply the Nominal Group Technique to rate, rank, and narrow the field of variation contributors to identify root causes of performance issues.
- Define the hypothesis tests to conduct that will validate the root causes.
- Define, prioritize, and plan your corrective actions.
- Implement the corrective action plan.
- Monitor the process performance measures to validate the corrective actions.
