A tool and technique used in the Develop Project Charter process is:

According to the PMBOK® Guide (Project Management Body of Knowledge), specifically within the Project Integration Management knowledge area and the Develop Project Charter process:

Expert Judgment (Option B): This is a primary tool and technique used during the initiation of a project. It involves taking into account the perspective and expertise of individuals or groups with specialized knowledge in functional areas, industry groups, or technical disciplines. For the Project Charter, expert judgment is used to evaluate the inputs (such as the business case and agreements) to ensure the project ' s high-level boundaries and strategic alignment are sound.

Meetings (Option C): While meetings are listed as a tool and technique in many processes (including Develop Project Charter), Expert Judgment is often considered the more fundamental professional technique cited in PMI literature for the high-level decision-making required during initiation. However, in modern PMBOK editions, both are valid; but in standardized exam contexts, Expert Judgment is frequently the " best " answer for determining project feasibility and strategic alignment.

Change Control Tools (Option A): These are tools and techniques specifically for the Perform Integrated Change Control process, used later in the project to manage changes to baselines.

Analytical Techniques (Option D): While used in various processes to analyze data (such as trend analysis or variance analysis), they are more prominently featured in the Monitor and Control and Close Project or Phase processes rather than the initial chartering phase.

In the PMI framework, Expert Judgment from stakeholders, consultants, or professional associations ensures that the Project Charter provides a valid foundation for the project, authorizing the project manager to apply organizational resources to project activities.
