I do not intend to teach CPM in a few short paragraphs. I will present some items that you must understand about CPM. The acronym "CPM" can be and is often misunderstood. CPM stands for Critical Path Method. The misconception by many who use, specify and rely on the meaning of "Critical Path." In its simplist terms and how it was used mostly when first conceived and applied to projects is the longest time duration hard logic path of work to the end of the project, providing you with the earliest project forecasted completion.

Well, for the purest, that definition holds true today, But what you must be aware of is that any process over time changes through use by the many. What you should also understand is that the original concept of CPM counted on the users (schedulers) to fully understand the scope of an activity including all materials and effort required. Today after more than 50 years of use and many, many users of the CPM process as interpreted by many CPM software creators, that CPM process has become convoluted and stretched in many directions. Most users today create poor schedules that abandon the basic rules.

The activities which comprise the workflow vary greatly in a number of ways: They carry variable risk, they require variations of resources and resource work patterns, they have variable safety aspects and rules, they are at ground level or at various elevations, they require fabricated materials and variable procurement, Every project workflow deals with these variations, yet very few schedules even hint of these considerations. Yet the project owners expect your workflow to remain valid throughout your project. IT CAN'T HAPPEN!

A good scheduling consultant realizes that your plan is based on what you know today plus your experience of seeing many tomorrows. We need the honest efforts of your team, your subcontractors, your suppliers and all who participate from schedule creation to the very last update.

You want a scheduling consultant who will work as an adjunct team member.
