Which of the following tools is often used in the Define Phase to clarify the project scope and objectives?

The charter is an essential tool used in the Define Phase of a Six Sigma project as it helps clarify both the project scope and objectives. This document outlines the purpose, goals, and deliverables of a project, serving as a foundational reference for the project team. By defining the scope, the charter helps prevent scope creep, which can derail project progress and focus. It succinctly communicates what the project seeks to achieve and sets the boundaries of the work to be performed. Moreover, a well-crafted charter can enhance stakeholder alignment and engagement, as it succinctly outlines the project’s importance and expected impact.

In contrast, the value stream map is primarily a Lean tool focusing on visualizing and analyzing the flow of materials and information. A histogram is used to display the distribution of data points, helping to identify patterns or outliers, and is more relevant in analyzing data rather than defining project scope. Lastly, a control plan details how controls will be implemented in the process to maintain quality over time, but it is utilized after the project has been defined and developed, rather than during the initial planning stage.
