Not only the data of portfolio items is evaluated within a review, but various change options of portfolio items are also considered and their effects are discussed. What-if scenarios are available in PPM to support this process. What-if scenarios can be created within reviews and include all or only the selected portfolio items of the review.
When you create a what-if scenario, the system automatically creates alterable copies of the assigned portfolio items, so that a what-if scenario displays a grouping of simulation versions or what-if scenarios of portfolio items.
In contrast to snapshot versions, what-if scenario versions are not only used for purely evaluative purposes, but can be used to simulate changes to the portfolio item data, without having to make direct changes to the original items. In a what-if scenario, you have your own reporting cockpit and your own dashboard to evaluate the simulated data and also compare it with the data of the original items.
Hint
Using Reviews
After you create a review and assign portfolio items to it, you can call various views and actions from this review. You can go to an item dashboard or a reporting cockpit to report the portfolio items. Only the items of this review are then displayed in the dashboard or reporting cockpit.
To analyze the progress of the portfolio items of the review, you can also call the version history of the items. If you want to simulate changes to portfolio items in a review, without changing the operational items, you can create what-if scenarios within a review.
You can use the scoreboard of a review to compare and prioritize portfolio items of a review according to defined criteria. When you open the scoreboard for a review, you first select a scoring model on which the comparison and prioritizing is to be based. A scoring model is defined in Customizing for PPM and contains a selection of portfolio item fields, each of which can be weighted differently in strength. For each field (attribute) of a scoring model, you also define a scoring for the possible field values in Customizing.
The system can determine a total score for a portfolio item based on the scoring of the field values of a portfolio item and the weighting of the fields. After you select a scoring model in the scoreboard, the score of the portfolio items of the review and the field values of the individual items, which are used to calculate the scores, are presented in a tabular manner in the scoreboard. If necessary, you can display details for calculating the scores, sort the portfolio items according to their scores, or export the result to Microsoft Excel. You can change the choice of scoring model at any time, and therefore, you can compare portfolio items in succession based on different criteria.
