Project management professionals have long recognized that sound measurement practices are integral to basic management activities such as project planning, monitoring, and control. And as more organizations adopt a management-by-projects approach, project managers are increasingly using measurement practices to make informed decisions and measure and quantify indices that guide product and process improvements. This paper examines the purpose of project management metrics and describes the three categories of metrics–things, people, and enterprise. It also discusses the relationship between metrics and project management maturity. It then explains the processes and procedures that organizations can use to establish and implement a metrics-focused culture that supports project management. It concludes by outlining guidelines that project professionals can use in their own organizations to establish metrics-focused and project-friendly cultures.
