Planalyzer-2 is a software tool calculating expected project delay and cost increase as a function of project management efficiency. The algorithm is based on a model of strongly correlated tasks or WBS elements sharing the same pool of human or financial resources.

Accurate prediction of expected project delay and cost increase is still challenging. Conventional "historical" modeling is based on comparison with similar projects in the past, with probability distributions of tasks and WBS elements designed by averaging multiple expert opinions.

Though well established and mandatory for several Government agencies historical modeling is time-consuming and expensive. To get reliable results, large number of independent experts has to be interviewed. To predict realistic project delay or cost increase mean values of task or WBS element distributions should exceed the planned ones arguing the project manager's costs and durations. Historical approach is applied primarily to long projects with stable risk profile but is impractical for analysis of high-risk dynamic projects.

With a model of strongly correlated tasks, Planalyzer-2 calculates project uncertainty and risk in real time bringing analyst's capabilities to the project manager's desktop. In the new methodology, major project management functions – minimization of milestone delay and resource sharing between tasks – are expressed mathematically and built into the algorithm. Strongly correlated tasks are depicted by waves having normally distributed wavelengths. Milestone uncetainty and risk are associated with degree of coherence of task waves in the vicinity of milestone. Asymmetry of milestone disribution is caused by random correlation of delays of several tasks. Some project parameters (average task CoV and milestone delay) are calculated directly from the project file, the example is presented by a table below:

Ibico's Planalyzer-2

	vPlanalyzer-2 analyzes Microsoft Project schedules and Microsoft Excel Work Breakdown Structures (WBS).
	Calculates probability density and cumulative probability (S-curve) of major milestones and WBS "Totals".
	Calculates milestone's "Tornado Charts".
	Compares milestone or WBS "Total" S-curves calculated without user input ("Schedule Risk") with S-curves based on user's estimate of task CoV (Coefficient of Variation) and Risk Register filled by user.
	Completes project analysis in several minutes (or several hours, if the project is very large, over 10,000 tasks or WBS elements).
