Statistical PERT uses standard functions for the normal distribution that come built-in to Microsoft Excel. Using these two functions, SPERT can create endless estimates with probabilities ranging between 0 and 100%. SPERT allows estimators to subjectively indicate how likely the most likely outcome really is. With SPERT, an estimator’s subjective opinion changes the SPERT standard deviation, and that affects the SPERT-created probabilities associated with SPERT estimates. To be used in conjunction with the accompany article Introducing Statistical PERT.
While numerous key performance indicators (KPIs) typically influence IT projects generally, the benefit of tracking all of them may be outweighed by the cost to do so. Therefore, each project must carefully select and manage those KPIs most relevant to its specific situation. This sample template can be used to define KPIs; also included is a table with examples of possible KPIs for each of the previously defined project-critical success factors (PCSFs) and a metric (measure and dimension) for each KPI. Use in conjunction with the article Determining IT Project Health.
