Crucial Tasks Chart
In addition to sensitivity charts, the results of
sensitivity analysis can be presented on the Crucial tasks Gantt
chart.
Each task can belong to one of three categories:
To explain crucial tasks, we use the “spring analogy”. Let us
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).
Crucial tasks may not lie on the critical path; however, in many
cases, crucial tasks will lie close to the critical path because they
are defined by the project schedule structure and risk and
uncertainties associated with each task. Critical path calculations
take into account only the project schedule structure.
Viewing the Crucial Task chart
By default, the Crucial Tasks View is not shown on the Analysis
Workflow bar. The Crucial Tasks view provides another analysis view to
investigate the root causes of project uncertainty.
1. If the Crucial Tasks View does not appear on the
Workflow bar, click the All
Views button.
2. Click on the Crucial Tasks icon
to open the view. Crucial tasks are color-coded, red indicating tasks
that are most crucial.
3. Double-click on a crucial task in the Gantt
chart to view distribution charts and statistics for the selected
task.
4. Double-click on a risk (arrow) to view the Risk
Properties of a risk assigned to a crucial task.
