A PERT/CPM is a project diagram, much like a flow chart, used to identify various stages in a project. This technique combines a Program Evaluation and Review Technique diagram, and a Critical Path Method diagram. A PERT diagram is used to illustrate worst-case, best-case and most likely ...
PERT and CPM also differ in terms of how they estimate. For example, as we’ve seen above,PERTuses a three-point method to forecast time, while CPM only has one measure for estimating. They also differ in that PERT is used with time is more valuable than the cost in planning. CPM is...
Additionally, project managers can use project scheduling techniques to increase the accuracy of their time estimates and minimize schedule risk. Thecritical path method(CPM) is an equation that shows the longest possibletimelinefor the project. TheProgram Evaluation and Review Technique(PERT) also visu...
This technique is used to estimate project duration, identify possible risks, and estimate the durations of each activity. A PERT can be a more visual representation than a CPM. 3. Line of balance (LOB) This technique looks at productivity rates and crews associated with specific scopes of wor...
The CPM allows project managers to identify potential risks and their impact on the project schedule. By analyzing the critical path and considering the float or slack time, project managers can predict the effects of delays and make adjustments to mitigate risks. ...

From pre-construction to project closeout, keep all stakeholders in the loop with real-time collaboration and automated updates so you can make better, more informed decisions, all while landing your projects on time and within budget. The Smartsheet platform makes it easy to plan, capture, mana...
By the way, around the same time, a similar technique —PERT(Program Evaluation and Review Technique) was developed too. Although the interest in the CPM had diminished by the early 1960s, some businesses began to apply it to oversee large projects (including Catalytic Construction and Mauch...
Project managers have come up with a PERT/CPM technique to get the best of both worlds. This technique beautifully brings together theoldand thenew. nTask uses this technique to help you with your critical path. It allows you to break down the project events into tasks and subtasks. ...
2. Program evaluation and review technique (PERT) This technique is used to estimate project duration, identify possible risks, and estimate the durations of each activity. A PERT can be a more visual representation than a CPM. 3. Line of balance (LOB) ...
