Which of the following tools are used for quality planning? (Select Two).

Cost / Benefit analysis is a key tool in quality planning used to evaluate the financial benefits of investing in quality activities versus their associated costs, helping to prioritize quality efforts. This analysis ensures that the chosen quality initiatives provide sufficient value to the project.

A network diagram is primarily used in project schedule management to illustrate the sequence of project activities and their dependencies, not for quality planning.

Benchmarking involves comparing current project practices or planned quality processes against those of other projects, organizations, or industry best practices. This comparison identifies areas for improvement and helps establish achievable quality targets during the planning phase.

Critical Path Method (CPM) is a schedule network analysis technique used to determine the longest path through the project schedule, which is a scheduling tool, not a quality planning tool.

Parametric estimating is a technique used for cost or duration estimation, where an algorithm is used to calculate cost or duration based on historical data and project parameters, not for quality planning.
