Agile Project Management vs. Critical Path Method

The Critical Path Method (CPM) of project management is very commonly used in the management of construction projects.

CPM works very well when the components of the design and the project are mostly known to all responsible parties. CPM focuses on either a single value-delivery event such as the completion of a building or in major phases such as turning over a floor at a time.  

Management Tools: Agile Project Management vs Critical Path Method (CPM).

CPM does not work as well in situations where there are significant “Known-Unknowns” about the plan CPM really breaks down when there are “Unknown-Unknowns”:

  • The final destination isn’t crystal clear; even to the leader
  • The path to get there has unknowns
  • The tools and tactics required to get there aren’t known to the team

In these situations more agile management methods are required either in conjunction with or to replace CPM:

There are similarities between all methods.  Develop the systems that work best for your company at this point in time.




Definitions for The Business of Building
Building a project requires knowledge and skill in using thousands of construction specific definitions, acronyms, and metrics. Building a business including the development of people has its own vocabulary that forms the foundation of communication.
Planning is Useless
Planning how to build a project and planning how to build a contracting business are VERY different and must be approached with a different mindset. When planning ‘how’ to build a project the ‘what’ is mostly known.
Time-on-Tools and Minimum Required Installation
Labor productivity IS NOT the biggest problem with field productivity. Under similar conditions the variation in how fast two crafts people actually “turn wrenches” is about 2X but there are far bigger problems to tackle. Focus on these three areas.
