What Impact Analysis can tell you
The Impact Analysis tool examines a set of elements, and finds out what else is happening to those elements, outside your project. It does this based on what state your element is now. So, if your element is ‘branched’, the Impact Analyzer will tell what the impact would be making it ‘planned’. If ‘planned’, what would be the imact if you made it ‘Implemented’.
The list of elements which the analyzer processes can come from:
- Some or all of the elements in a diagram
- All the elements under a project. Beware: for a large project, with lots of elements, this might take some time.
For each element, Portfolio Manager will examine if any other projects
- have branched, or are planning to change
- have branched with a view to retiring, or are planning to retire
- whether the element is connected to anything in the baseline which has branches, or planned changes
In some cases, the analyzer will flag ‘fatal’ impacts – if you were to continue, the model would become inconsistent. For example, an Implemented element can only have one ‘Planned’ or ‘PlannedToRetire’ element. so if you try to create a second one, the analyzer will flag a ‘fatal’ impact, which can be clearly seen in the analyzer.
