Explanation:

Project management can be defined as the process of designing, planning, developing, leading and execution of a project plan or activities using a set of skills, tools, knowledge, techniques and experience to achieve the set goals and objectives of creating a unique product or service. Generally, projects are considered to be temporary because they usually have a start-time and an end-time to complete, execute or implement the project plan.

Benchmarking refers to a process that continuously identifies, understands, and adapts outstanding processes found inside and outside an organization. Well-run organizations compare not only against competitors (where possible) but against best-in-class organizations as well.

This ultimately implies that, benchmarks are used to measure a firm's products, services, or processes performance in comparison with another business firm that are considered or assumed to be the best in that industry.

Hence, the planning, design, building and implementation phases considered to be benchmarks.
