Presenting the Analysis
The final stage in this process is to prepare a clean final copy of the analysis. This should combine the draft analysis (see above) with your scheduling and analysis of resources to show when you anticipate that jobs should start and finish.
There are two formats for this clean copy. The choice of the most effective form of presentation comes down to the circumstances of the analysis and personal taste.

Gantt Charts
A redrawn and scheduled version of the analysis above is shown below, in the format of a modified Gantt chart:




Here time is marked out in columns across the chart, with individual tasks represented as arrows terminating at dots. The length and positions of the arrows show the start date and duration of the tasks.

You may prefer to show tasks in pure Gantt format, as solid bars rather than arrows terminating in dots. Similarly you may prefer not to show the linkages between related tasks - this is a matter of personal taste and personal convention.

The Critical Path is the longest sequence of dependent activities that lead to the completion of the plan. Any delay of a stage in the critical path will delay completion of the whole plan unless future sequential activities are speeded up.


PERT Charts
PERT stands for Programme Evaluation and Review Technique. Here circles represent completion of tasks, with linking lines showing the time taken to achieve the tasks. The critical path for the project is shown as the horizontal series of tasks.
Note that in the diagram below we are using dotted lines to link completed tasks back to the appropriate stages of the critical path. These lines serve to tidy the diagram and do not represent tasks to be carried out. This diagram shows our example critical path analysis in PERT format:




Carrying out the example critical path analysis above shows us:

That if all goes well the project can be completed in 10 weeks
That if we want to complete the task as rapidly as possible, we need:
1 analyst for the first 5 weeks
1 programmer for 6 weeks starting week 4
1 programmer for 3 weeks starting week 6
Quality assurance for weeks 7 and 9
Hardware to be installed by the end of week 7
That the critical path is the path for development and installation of supporting modules
That hardware installation is a low priority task as long as it is completed by the end of week 7
Summary
Critical Path Analysis is an effective and powerful method of assessing:
Tasks which must be carried out
Where parallel activity can be carried out
The shortest time in which a project can be completed
Resources needed to achieve a project
The sequence of activities, scheduling, and timings involved
Task priorities
etc.
An effective critical path analysis can make the difference between success and failure on complex projects, and can be an effective tool for assessing the importance of problems faced during the implementation of the plan.
