Generalized Analysis of Value Behavior over Time as a Project Performance Predictor

By Bob Prieto

USA


As projects have grown more complex our performance analysis frameworks have remained largely unchanged even as newer more powerful tools have become available to manage and manipulate large volumes of data. Newer analytical tools provide deeper insights into existing data sets especially from a statistical point of view but we continue to use traditional project metrics to assess project performance on both a retrospective as well as prospective basis.

Whether our measure of project achievement is cost, schedule, physical % complete, risk or manhours we look at a relatively common set of “achievement” metrics that include absolute values (datum); changes in those values (progress) and their rate of change (progress rate). In limited instances we consider changes in the rate of progress (ramp rate) but do not more broadly analyze this throughout the project.

Higher order performance measures that look at disruption and overall efficiency of delivery are not typically considered.

The analog for each of these achievement metrics can be seen in the following table.

In this paper we will consider some potential index type metrics to help evaluate the level of potential “disruption” that exist in a project plan or is subsequently realized. In addition we will look at how the various “disruptions” combine to impact the overall efficiency of the project. These indices correspond to third and fourth order derivatives, jerk and snap, in a spatial context and are subjects of one or more patents pending.
