Critical path presentation for timely project completion
2 likes370 views
The document discusses the critical path method (CPM) for project management, which helps identify the longest sequence of tasks that affect project completion. It explains key concepts such as critical activities, float, and resource loading, highlighting the importance of effective management to prevent delays. Additionally, it mentions various software packages commonly used for CPM, with Microsoft Project being the most widely utilized for project planning and analysis.

- 2. The critical path is composed of those tasks whose finish dates affect the finish date of the overall project. In other words, if a critical task finishes late, the project will likely finish late also, unless you are able to adjust to the delay and make up time elsewhere. When you control critical elements of the construction process, you will get more reliable results. Clearly, with the added controls that are part of a complete contraction quality control plan, you’ll have fewer problems to fix and higher levels of quality from start to finish. A critical path analysis is a diagrammatical representation of what needs to be done and when. Timescales and costs can be applied to each activity and resource.“
- 3. What is Critical Path Method (CPM) CPM Deliverables • Calculates the longest path of planned activities to the end of the project • The earliest and latest that each activity can start and finish without making the project longer • Determines “critical” activities (on the longest path) • Prioritize activities for the effective management and to shorten the planned critical path of a project
- 4. The Critical Path Method ( CPM) Approach. List the Activities & Relationships Create a Start Node Draw Arrows from Start Node to the First Activity’s Node Double Check for Missed Relationships Repeat Process from Successors for all Activities Sequentially Arrange All Activities from Start
- 5. Critical Path Method- Definitions Float (slack) - amount of time that a task can be delayed without causing a delay to: -subsequent tasks (free float) -project completion date (total float) Critical path is the sequence of activities which add up to the longest overall duration. It is the shortest time possible to complete the project. Any delay of an activity on the critical path directly impacts the planned project completion date (there is no float on the critical path). A project can have several, parallel, near critical paths. An additional parallel path through the network with the total durations shorter than the critical path is called a sub-critical or non-critical path. Critical activity – activity with zero float
- 6. Nodes- Late finish time (LF) is the latest time that an activity may finish without delaying the entire project . Total Float= Late Start - Early Start OR Late Finish-Early Finish LS LF DURATION (-) ES EF DURATION (+) Critical Path Method- Definitions
