The roadmap a team uses to manage and control resources, time, and money to meet improvement objectives is known as the...

The project charter serves as a foundational document in project management, particularly in the context of continuous improvement initiatives such as those guided by Six Sigma methodology. It is a formal agreement that outlines the goals, scope, and stakeholders of a project. By defining the project's objectives, scope, timeline, resources, and budget, the project charter helps the team stay aligned and focused on achieving the improvement objectives.

This document functions as a roadmap, as it allows the team to navigate through various phases of the project by setting clear parameters for managing resources, time, and costs effectively. The project charter ensures that everyone involved understands the project's aims and the framework within which they will operate.

In contrast, the other options fulfill different roles in the project management process. A problem statement identifies the issue needing resolution but doesn't provide management or control over resources. The goal or AIM statement specifies what the project seeks to achieve but lacks the detailed logistical framework of the project charter. A business case outlines the justification for the project, including its potential benefits and costs, but does not typically serve as a roadmap for managing the project itself. Thus, the project charter is the most accurate choice for describing the document that guides resource management, time allocation, and budget control to meet designated improvement objectives.
