Lean Six Sigma Refresher
A Risk Register in Lean Six Sigma (LSS) is a structured document used to identify, assess, and manage risks that could impact the success of a project. It’s a proactive tool that helps teams anticipate challenges and plan mitigation strategies before issues escalate.
📄 Purpose
Visibility: Centralizes all known risks in one place.
Prioritization: Helps teams focus on high-impact risks first.
Accountability: Assigns ownership for monitoring and resolving risks.
Decision Support: Provides data for sponsors to make informed choices.
Continuous Improvement: Encourages proactive thinking rather than reactive firefighting.
✅ Value in LSS Projects
Prevents surprises by anticipating risks early.
Builds trust with stakeholders by showing proactive management.
Strengthens the Define and Control phases of DMAIC.
Provides a living document that evolves as the project progresses.
🔧 When to Use
Define phase: Capture initial risks when scoping the project.
Throughout DMAIC: Update as new risks emerge.
Control phase: Document residual risks and monitoring plans.
Takeaway: The Risk Register is the safety net of Lean Six Sigma projects—it ensures risks are visible, prioritized, and actively managed, so improvements are delivered smoothly and sustainably.
