Critical Path Analysis

Procedure for calculating the critical path and floats in a network.

Critical Path Method (CPM)

A technique used to predict project duration by analyzing which sequence of activities has the least amount of scheduling flexibility. The Critical Path Method is a modeling process that defines all the project's critical activities that must be completed on time. The start and finish dates of activities in the project are calculated in two passes. The first pass calculates early start and finish dates from the earliest start date forward. The second pass calculates the late start and finish activities from the latest finish date backwards. The difference between the pairs of start and finish dates for each task is the float or slack time for the task (see Float).

Work Breakdown Code

A code that represents the ‘family tree’ of an element in a work breakdown structure.

Work Breakdown Structure

Way in which a project may be divided by level into discrete groups for programming, cost planning and control purposes.  Note: see also ‘work package’ (The WBS is a tool for defining the hierarchical breakdown of work required to deliver the products of a project. Major categories are broken down into smaller components. These are sub-divided until the lowest required level of detail is established. The lowest units of the WBS become the activities in a project. The WBS defines the total work to be undertaken on the project and provides a structure for all project control systems.)

Work Load

Work load is the amount of work units assigned to a resource over a period of time.

Work Package

A group of related tasks that are defined at the same level within a work breakdown structure (In traditional cost/schedule systems, the criteria for defining work packages is as follows:  1) Each work package is clearly distinguishable from all other work packages in the program. 2) Each work package has a scheduled start and finish date. 3) Each work package has an assigned budget that is time-phased over the duration of the work package. 4) Each work package either has a relatively short duration, or can be divided into a series of milestones whose status can be objectively measured.  5) Each work package has a schedule that is integrated with higher-level schedules).

Work Units

Work units provide the measurement units for resources. For example, people as a resource can be measured by the number of hours they work.
