Which tool or technique of Plan Quality involves comparing actual or planned practices to those...

According to the PMBOK® Guide, specifically within the Plan Quality Management process, Benchmarking is a primary data gathering technique used to establish quality standards and identify improvements.

Definition: Benchmarking involves comparing actual or planned project practices or the project ' s quality standards to those of comparable projects to identify best practices, generate ideas for improvement, and provide a basis for measuring performance.

Source of Comparison: The projects used for benchmarking can be within the same organization, from another organization, or within the same application area. They can even be from a different industry (e.g., a construction project benchmarking its logistics against a retail company).

Objective: The goal is to set a " benchmark " or a standard of excellence. By seeing how others achieve high quality, the project team can adopt those methods to improve their own processes and deliverables.

Comparison with other options:

A. Histogram: This is a data representation tool (a bar chart) used to show the central tendency, dispersion, and shape of a statistical distribution. It is used to visualize data but not to compare practices against external projects for improvement ideas.

B. Quality audits: This is a tool used in the Manage Quality process (Executing phase). An audit is a structured, independent process to determine if project activities comply with organizational and project policies, processes, and procedures. It is an internal check of compliance rather than a comparison against external " best practices. "

D. Performance measurement analysis: This is a general term often associated with Control Costs or Control Schedule. It involves comparing the baseline to actual performance to determine if a variance exists. It does not inherently involve looking at other projects to generate new improvement ideas.
