SLIM-Estimate

SLIM-Estimate

Why manage my project to a work plan that has only a 50% probability of success? Shouldn't we be managing to a 75% or even an 80% or 90% plan?

 

The 50% solution is based on the expected value (the solution with a 50% probability of achieving the same or better values for schedule, effort, cost, and reliability). Each of the inputs to an estimate - size, application complexity, and productivity - has some uncertainty associated with it. If any one of your input parameters (size, for instance) increases significantly from the original estimate, it makes sense that the actual outcome will vary from the estimated outcome.

Time, Effort calculations not affected by changes to "Person Hours per Person Month" field

 

When I change the Person Hours per Person Month field on the Accounting tab of the Solution Assumptions dialog, there is no change to the total schedule and effort for the project. Why is this?

Many SLIM-Estimate and SLIM-Control users have asked why their overall schedule does not change when they change the value of the "Person Hours per Person Month" field,  Solution Assumptions screen, Accounting Tab.

Purpose of Gearing Factors in SLIM-Estimate

 

What is the purpose of the gearing factor?

Gearing factors are used to convert projects with many different sizing units (objects, modules, or use cases for example) back to a common sizing unit: the Basic Work Unit. The Basic Work Unit represents the smallest sizing unit that is common to all projects.
