**Concept of Performance Intensity (PI)**

Think of Performance Intensity a miles-per-hour unit of measure. Reflect on how you use this value in your daily driving. By quickly glancing at a speedometer, you can determine whether you are driving too slowly (to make deadlines) or too fast (to endanger others around you). Important to note is that the speedometer is a self-management tool.

Likewise, Performance Intensity is a unit of measure that can be presented to those performing the work, so that they can self-manage. This is an important distinction from Dominant Project Management’s approach to Project Time Management, where Project Controls functions as a watchdog, monitoring project performance and reporting on deviations from plan.

**Performance Intensity is Based on the Activity Duration**

Performance Intensity is based on the activity duration, and presupposes that it reflects a realistic (deterministic) estimate of the number of Continuous Crew Days that an activity will take to perform and complete. Such durations should be devoid of any padding, buffers, contingency or other adjustments to puff of the duration beyond what is needed to perform the work in one continuous effort.

**PI is a Rate, Expressed as a Fraction**

In order for Performance Intensity to function as a miles-per-hour, it must be a rate. Rates are expressed as fractions, with numerators and denominators. In Performance Intensity, the numerator reflects Duration Days, which is cumulative value derived by summing the activity durations of select groups of activities. The denominator is Allotted Time, the amount of time associated with the subset of Durations Days in the numerator.

**Performance Intensity Core Formulas**

All PI Core Formulas follow the same fractional value described in the previous paragraph. The main difference is in which subset of activities one is examining. For instance:

- Planned PI:Focuses on activities yet to be performed. Durations Days sum the durations of activities yet to be performed, and Performance Period reflects the time available to perform those activities.
- Actual PI:Measure activities that have been performed, fully or partially. Durations Days sum the durations of activities that have been “earned” during a designated period of time (Performance Period).
- Catch-Up PI:Focuses on activities that remain to be performed. Durations Days sum the durations of remaining activities. Performance Period reflects the time remaining to perform those activities.(Top of Page)

**Performance Intensity Derivative Formulas**

The above Core Formulas can be combined and compared to one another in various ways. They can also be serialized, so as to show trends from one reporting period to the next. Finally, they can be applied to select subsets of Schedule activities.

- Compound PI: This is where various Core Formulas are combined to derive insightful statistics about performance.
- Trending PI: Various extrapolations of PI across time so as to show trends.
- Targeted PI: This is where PI is applied to any subset of activities that can be isolated, using the filtering functionality of the scheduling software, and the activity codes assigned to the activities. Examples include:
*Area PI*: By building, by floor, by area*Phase PI:*By project phase*Responsibility PI:*By performing entity*MCP PI:*PI by Momentum Checkpoint (see below)(
