Scope Statement

A Scope Statement in Lean Six Sigma (LSS) is a foundational document created during the Define phase of DMAIC. It clearly outlines the boundaries of a project—what is included, what is excluded, and what the team is expected to deliver. By setting these parameters early, the Scope Statement prevents scope creep and keeps the project focused on solving the defined problem.

📄 Purpose

  • Clarity: Ensures all stakeholders understand the project’s boundaries.

  • Focus: Keeps the team aligned on what matters most.

  • Efficiency: Prevents wasted effort on activities outside the project’s intent.

  • Accountability: Provides a baseline for measuring success.

✅ Value in LSS Projects

  • Provides direction and discipline during Define and Measure phases.

  • Builds trust with stakeholders by setting realistic boundaries.

  • Serves as a reference point when evaluating requests for changes.

  • Strengthens project governance by aligning with the Project Charter.

Takeaway: The Scope Statement is the guardrail of Lean Six Sigma projects—it ensures the team stays focused, avoids distractions, and delivers results within agreed boundaries.
