A Project Charter is a fundamental document in Lean and Six Sigma that defines the purpose, scope, and structure of an improvement initiative. It serves as the official starting point of a project, providing clarity, alignment, and direction for all stakeholders. Typically developed during the Define phase of the DMAIC cycle, the Project Charter acts as a roadmap that guides the team from initiation to completion, ensuring that objectives and expectations are well understood.
In quality and process improvement methodologies, the Project Charter plays a crucial role in preventing ambiguity and ensuring strategic alignment. It links improvement projects directly to organisational goals, ensuring that time and resources are invested in initiatives that create measurable value. The concept originates from project management best practices and was adopted into Lean Six Sigma to provide structure and discipline at the start of every project. Without a well-defined charter, teams risk unclear objectives, uncontrolled scope, and poor results.
A well-prepared Project Charter provides structure, alignment, and accountability. It strengthens communication between stakeholders, supports data-driven decision-making, and ensures that improvement activities remain focused on measurable goals. In Lean Six Sigma, the charter is the cornerstone of project success and sustainability.
