Critical Path Myth, Part 1: Confusion and Illusion

Overview Blog Series Abstract: The widespread faith in the Critical Path Concept is not justified by the facts. Still, those with a vested interest in their projects finishing timely continue to support the Critical Path Concept and embrace recommended practices that they are told will lead to more successful projects. This three-part blog series is intended […]

Is Total Float All That ?

Is Total Float All That ? After five decades of Critical Path Method, we have all become used to the term Total Float, and it has made its way into how we interpret the Project Schedule, and how we actually manage our Projects. The question I dare to ask is this: is the Total Float […]

How We Confuse Ourselves

How We Confuse Ourselves  A fair amount of confusion and contradiction permeates among and across the literary works that deal with Project Time Management. Some of this confusion is inherent in the subject matter itself and cannot be avoided. But much of the confusion is entirely avoidable. However, Confusion Avoidance requires both Will and Influence […]

Realistic Schedules Require Prudent Expectations

What good are Projects Schedules if they are not realistic at their core?  I mean, we ask our Project Schedules to do so much for us. We use them to direct our work, and to validate our progress payments. We use them to resolve disputes over time usage, including claims of delay, acceleration, and loss […]

What Architects Can Teach Schedulers

There was an uncomfortable silence in the room. The Architect and the Owner (his Client, the End User of his design effort) sat opposite one another, each staring down at the table. Eye contact was becoming increasingly awkward. At last, the Architect broke the silence, trying one last time. “Jennie, if you tell me what […]

A Meeting of the Minds

One topic that continues to surface every few months in various Internet forums has to do with what it takes to produce a good Project Schedule. That the question continually surfaces is strong indication that there is still much interest, if not downright uncertainty, regarding what processes and core elements will predictably and consistently yield quality […]

What Lead/Lag Values Mean

Despite decades of debate on the subject, the Planning/Scheduling community remains deadlocked over what the terms Lead Values and Lag Values actually stand for. Some say “performance of work,” while others say “passage of time.” I happen to think that there will never be agreement until there is a rather dramatic paradigm shift – from […]

Zero Sum Game and Project Conflict

The amount of Conflict experienced on most construction projects today might be greatly reduced if only the Project Team would have the willingness to understand the sources of such Conflict and the resolve to take corrective steps. Project Conflict comes in two forms: Intrinsic Tension and Extrinsic Tension. Intrinsic Tension: Is borne out of the […]

The Role of the Schedule: Coordination or Prediction?

Peruse the multitude of Project Management, Project Time Management, and Project Controls groups on LinkedIn and at least once or twice a month you will find debates over some technical aspect of what goes into a good Project Schedule, or of what constitutes recommended scheduling practice. Words fly, tempers rise, heels dig in, and … in the […]

“Most Projects Most of the Time” Makes Little Sense

“Most Projects Most of the Time” Makes Little Sense I am of the firm opinion that the conventional wisdom with respect to how to manage projects, which is proclaimed by its proponents as being aimed at “most projects most of the time,” is not particularly well suited for the Construction Industry. I find the entire […]
