There are many articles recently about the traditional project triple constraints: scope, schedule and budget, and how PMI recently in the PMBOK Guide, Fourth Edition (hereafter, the PMBOK Guide) replaced the triple constraints by a larger list of project constraints that project managers should consider.
The list of project constraints proposed by PMI is an extension of the triple constraints. Besides scope, schedule and budget, it includes resources, quality and risks. And it is not the full list, to quote the PMBOK Guide:
Managing a project typically includes:
- Identify requirements,
- Addressing the various needs, concerns, and expectations of the stakeholders as the project is planned and carried out,
- Balancing the competing project constraints including, but not limited to:
- Scope,
- Quality,
- Schedule,
- Budget,
- Resources, and
- Risk.
So, are the traditional project triple constraints still relevant? Here are some of my thoughts
