Establishes the foundations of Lean Six Sigma and its customer-focused approach to improvement. Learners examine what Lean and Six Sigma each contribute, why they are used together, and the principles that guide effective improvement work. They then identify internal and external process customers, gather the voice of the customer, distinguish needs from proposed solutions, and translate customer needs into measurable requirements.

Develops the ability to understand processes as they actually operate and use reliable data to guide improvement decisions. Learners map and observe workflows, identify gaps between documented and actual processes, and examine how involvement and change management affect adoption. They also design data collection plans, assess measurement reliability, and select appropriate data displays to reveal patterns and support evidence-based decisions.

Builds the analytical skills needed to identify what is really preventing a process from performing effectively. Learners apply root cause analysis, verify suspected causes with data, distinguish value-adding from non-value-adding activities, and identify common forms of waste. They also examine where time is lost through waiting, apply appropriate flow improvements, and generate and evaluate multiple solution options rather than adopting the first proposed answer.

Focuses on designing better processes and sustaining improvements over time. Learners explore prevention, Design for Six Sigma, design thinking, and agile approaches before applying DMAIC to improvement projects. The module also covers rapid improvement events, operational excellence, project selection, governance, and the standards, measures, and ownership needed to prevent improvements from reverting after implementation.

Provides practical reference and application resources that help learners consolidate and apply the Lean Six Sigma capabilities developed throughout the course. Resources reinforce customer requirements, process mapping, data collection, root cause analysis, waste identification, flow improvement, solution generation, prevention, design approaches, DMAIC, and sustainment. The section also includes an integrative project in which learners define and plan a complete improvement project for a real process, supported by measurable customer requirements, process and data analysis, verified root causes, solution selection, DMAIC sequencing, and a control plan that sustains the improvement.
