The preceding video shows a simple example of a scoring model. You want to derive the value of the Derived Risk field in portfolio items from the probability of technical success and the respective development costs of the items.
You must define a scoring model in SAP Portfolio and Project Management Customizing, which contains both fields (scoring model attributes) Probability Technical Success (PROBT) and Development Cost (COSTD). The probability of technical success is more important to you for assessing the risk than the development costs. Therefore, you give the attribute PROBT more weight than the attribute COSTD.
Define intervals for each attribute and assign scores to these intervals. For example, if the probability of technical success is between 0 and 25, there is a high risk; therefore, you assign a score of 100 to this interval. If the probability is between 26 and 50, the risk is somewhat less; therefore, you assign the interval a score of 90.
Define intervals and scores for the development costs in the same way. COSTD is a currency-dependent field; therefore, specify the relevant currency for the intervals. To use the scoring model as a service for the Derived Risk field, the field configuration of this field must allow the service Scoring model.
The PPM administrator assigns the scoring model defined in Customizing to the portfolio item Derived Risk field at the level of the parent portfolio bucket in the section Field Service Configuration.
