In addition to the sensitivity chart, results of sensitivity analysis can be presented on the Gantt chart.
Each task An activity or job which has a start date and time, an end date and time, a duration, and other properties. A Project is comprised of tasks. can belong to one of three categories:
|
1 |
Red bar |
Tasks that have the most affect on the project duration– crucial tasks. There is a strong correlation between the task and project duration. |
|
2 |
Yellow bar |
Tasks which have some affect on project duration, i.e. there is a correlation between task and project duration |
|
3 |
Green bar |
Small or no correlation between the task and project duration |
To explain Crucial tasks, we use the “Spring analogy”. Let’s assume that each task is a spring in a big system of springs. When we start moving springs back and forth, we find that some of them significantly affect the movement of the full spring system, while others do not. The amount of movement depends on how springs are connected to each other (links between tasks) and how flexible they are (the type of risks and uncertainties they have assigned).
Tip: Crucial tasks may not lie on the critical path; however, in many cases, crucial tasks will lie close to the critical path. This is because critical tasks are defined by the project schedule the timing and sequence of task within a project. A schedule contains tasks with dependencies, as well as other project information. structure and risk A stochastic event that can be applied to tasks or resources and affects project schedules. Risks are defined by name, chance of occurrence, outcome, and time of occurrence. Risk can be global (for all tasks or resources in project) and local (for particular task or resource in project). Global risks can be added using the Risk View. Local risks can be added using the Task Information dialog box or the Resource and uncertainties associated with task. Critical path calculation takes into account only the project schedule structure.
Note: The Crucial Task view Located on the left of the RiskyProject workspace, the Workflow bar allows you to quickly select and open Views. The order of the views in the workflow bar reflects the recommended project risk management workflow. The Workflow bar can be turned on and off from within the Options dialog box (view tab) or the View menu. In addition,the Workflow bar can be turned off by clicking the X in the title bar (top of workflow bar). is only available in the professional version of RiskyProject.
