The traditional approach to project planning and execution is to allow past experience to dominate. (If we did it that way before, we will do it that way again). Let's look at a typical approach, one which provides ample opportunities for failure.
Rough concepts are prepared and a scheme laid out. Contingency ranges are small and often inadequate. Alternatives are developed without rigorous thought based upon the random creative instincts of the project manager.
While the owner's preferences are developed into a scope, the end use vision is rarely tackled.
This is especially true for translating the project owner's grand scheme of the business or operation several years after completion.
Once the project is under way, the disciplines work in relative isolation, very often feeding on "best estimates" and old information. For example, the owner's project manager may be sharing information with you at the same time as the board of directors are meeting in another city to change plans. Or a prime consultant may be giving information about a change to a consultant, while another discipline whose work will also be affected, carries on blissfully unaware until days or even weeks later when someone mentions the change. This occurs because everyone else thought that everyone else would let everyone else know. And this occurs because there is no structure or mechanism in place to know who knows what and what they know.
The downsides to this approach are many. The optimum design may not be selected. Uncertainties may not be limited or even identified. Decisions may not be made using the correct assumptions and good judgment may be clouded by emotion. There may be no link between the uncertainties and the contingencies. The owner's hidden agenda may not be incorporated into the scope, because somehow the project drifted and "got away" from the owner's wishes, or because not enough time was spent with the owner to uncover those wishes. Interdiscipline coordination is traditionally unoptimized and optimum problem solving techniques are usually not utilized.
There are several things that the forward-thinking office can do to get a project off to a better start and keep it on track.
It is a comparatively small effort to implement a rational approach to planning and execution. It is a comparatively large effort to get project managers to consistently use it, but then project managers usually take their cues from their leaders, so it is the upper echelon who will set the pace.
