According to the PMBOK® Guide, the Direct and Manage Project Work process is the process of leading and performing the work defined in the project management plan and implementing approved changes to achieve the project’s objectives.

Tools and Techniques: The formal tools and techniques for this process are:

Expert Judgment: Used to evaluate the inputs and the execution of the project work. This includes technical knowledge of the industry, specialized skills for the product, and management expertise.

Project Management Information System (PMIS): An automated tool (such as scheduling software, configuration management systems, or information collection and distribution systems) used to support all aspects of the project.

Meetings: Used to discuss and address pertinent topics when directing and managing the project work. These include kickoff meetings, technical meetings, and progress updates.

Comparison with other options:

A. Process analysis: This is a tool and technique for Manage Quality (specifically identifying improvements in the process), not Direct and Manage Project Work.

B. Analytical techniques: While a PMIS is used, " Analytical Techniques " is specifically listed as a tool for Plan Procurement Management or Monitor and Control Project Work, but it is not a primary tool for the execution of the work itself in this specific process.

C. Performance reviews: These are tools used in Monitor and Control Project Work and Control Procurements to compare actual performance against the baseline, rather than the act of performing the work.
