Tailoring is the process of selecting the appropriate combination of processes, inputs, tools, techniques, and outputs to meet the unique needs of a project during planning. The purpose of tailoring is to customize processes before applying them to ensure they meet the specific needs and expectations of stakeholders for that particular project. An exam question tests knowledge of tailoring by asking which choice best describes its purpose, with the correct answer being that tailoring selects the appropriate combination of processes and techniques for a project.
