Critical Path Drag
Critical path drag is a project management metric developed by Stephen Devaux as part of the Total Project Control (TPC) approach to schedule analysis and compression in the critical path method of scheduling. Critical path drag is the amount of time that an activity or constraint on the critical path is adding to the project duration. Alternatively, it is the maximum amount of time that one can shorten the activity before it is no longer on the critical path or before its duration becomes zero. In networks where all dependencies are finish-to-start (FS) relationships (i.e., where a predecessor must finish before a successor starts), the drag of a critical path activity is equal to whichever is less: its remaining duration or (if there is one or more parallel activity) the total float of the parallel activity that has the least total float.Stephen A.

Project Management
Project management is the process of leading the work of a team to achieve all project goals within the given constraints. This information is usually described in project documentation, created at the beginning of the development process. The primary constraints are scope, time, and budget. The secondary challenge is to optimize the allocation of necessary inputs and apply them to meet pre-defined objectives. The objective of project management is to produce a complete project which complies with the client's objectives. In many cases, the objective of project management is also to shape or reform the client's brief to feasibly address the client's objectives. Once the client's objectives are clearly established, they should influence all decisions made by other people involved in the project – for example, project managers, designers, contractors, and subcontractors. Ill-defined or too tightly prescribed project management objectives are detrimental to decision-maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Project Control
Total project control (TPC) is a project management method that emphasizes continuous tracking and optimization of return on investment (ROI). It was developed by Stephen Devaux. It builds upon earlier techniques such as earned value management, critical path method, and program evaluation and review technique, but uses these to track and index projected project profitability as well as the more traditional cost and schedule. In this way it aims to manage projects as profit and investment centers, rather than cost centers. Introduced with TPC are a variety of project management metrics and techniques, among them critical path drag, the value breakdown structure (VBS), Devaux's Index of Project Performance (the DIPP), Doubled Resource Estimated Duration (DRED), and Cost of Leveling with Unresolved Bottlenecks (CLUB). The Project Management Institute's monthly magazine PM Network reviewed the TPC methodology as making "solid points about what can be done to maximize ROI during ...

Drag Cost
Drag cost is a project management metric developed by Stephen Devaux as part of the Total Project Control (TPC) approach to project schedule and cost analysis. It is the amount by which a project’s expected return on investment (ROI) is reduced due to the critical path drag of a specific critical path activity Task (project management) or other specific schedule factor such as a schedule lag or other delaying constraint.Stephen A. Devau"The Drag Efficient: The Missing Quantification of Time on the Critical Path" Defense AT&L magazine of the Defense Acquisition University. Drag cost is computed at the activity level, but is caused by the impact at the project level due to: 1. A reduction in a project's expected value because of later completion, or 2. An increase in a project's cost due to its indirect costs being increased because of a longer project duration. Drag cost computation is often used on projects in order to justify additional project resources Resource refers to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
