Six Sigma Refresher

The DOQS Six Sigma Refresher is a set of supplemental learning modules where attendees can reinforce and extend Six Sigma skills acquired in prior training and developed on initial projects. It is intended for Six Sigma practitioners who may be struggling with certain tools or thought processes, and would benefit from a learning session that focuses on their problem areas and concerns.



Because the focus is on the specific problems of attendees, the agenda of every session is different. The first half-day is spent discussing the group’s experiences and concerns in applying Six Sigma thinking and tools in their work, resulting in a group Failure Model and Effects Analysis (FMEA) that identifies and prioritizes areas of concern or gaps in knowledge. The high RPN prioritized issues are organized into the subsequent learning modules agenda. As each module is covered, remaining items that need to be addressed outside of the Refresher are placed in a session Control Plan. The last half-day is spent refining that Control Plan and identifying follow-up activities that need to be pursued to assure that discussions throughout the Refresher agenda result in sustainable improvements. After Refresher completion, the cohort communicates their Control Plan to leadership.

Session Scheduling

A variety of scheduling options is available for planning and conducting Refresher sessions in your organization. Sessions are always scheduled in half-day increments, either back-to-back as full-day classes, or over time as regularly scheduled sessions attended by the same cohort of individuals. Scheduling options might include one day a week for a month, a half-day a week for two months, or any other variation that meets the needs of the attendees while minimizing any off-the-job impact. These options allow multiple cohorts of individuals to go through Refresher sessions in parallel while allowing the session agendas to remain focused on the specific needs of each cohort.

Commonly Selected Modules

  • Better process scoping using the SIPOC-PMAP feedback loop.
  • Better integrating FMEA columns back to the Charter, SIPOC, and PMAP.
  • Defining clearer units and defect types to enable more effective sigma score calculation.
  • Understanding the role of 3s control limits within 6s specifications.
  • Defining requirements in the SIPOC, while fully quantifying them in the Measure Phase.
  • Avoiding confusion between functional and technical requirements and specifications.
  • Applying internal controls thinking within the definition of process components.
  • Clarifying the role of dashboards and scorecards in the deployment and control of solutions.
