Sensitivity Analysis in Project management

As a project manager, it's important to be able to analyze your data and make informed decisions. In order to do this, you need to be aware of the sensitivities in your data. 

Sensitivity analysis is a technique used to understand the effects of changes in one or more inputs on the output of a model. It is the process of examining how the output of a model changes when one or more inputs are changed. This is a valuable tool for project managers, as it allows them to assess the risks and rewards associated with different decisions. It can be used to identify which input(s) have the greatest impact on the desired outcome, and help to make better decisions by understanding how sensitive the results are to changes in these inputs.

Sensitivity Analysis is recommended to be used in the following performance domains;

A sensitivity analysis typically involves varying one or more inputs (e.g. cost, time, scope) and observing the resulting change in the output(s). By doing this for different inputs, you can understand how each one impacts the results. This information can then be used to adjust your plans and decision-making as needed.

When doing sensitivity analysis, it's important to choose the right inputs to vary. Some factors may be more important than others, and you may not want to change them all at once. For example, in financial analysis, you might vary the interest rate or the amount of money invested, while in a project schedule you might vary the duration of the project or the resources required.

It's also important to understand how each input affects the results. For example, if you're varying the duration of a project, you need to know how much that will impact the other aspects of the schedule (e.g. how it will affect deadlines and workloads).

Once you've determined which inputs to vary and how they affect the results, it's time to start analyzing! This involves creating different scenarios based on your changes and seeing what happens. You can then use this information to make informed decisions about your plans and projects.
