Perform Branch Evaluation
 

This guideline provides a systematic approach for performing scenario evaluation within a branch of the pruned change process model. The term branch refers to a sub-hierarchy of the top level goal of the change process model. 

Perform the following steps
 
Compile the list of scenaria
A description of all possible scenaria within a branch is produced.
Evaluate scenario in a qualitative manner
For each alternative scenario in the branch, a qualitative evaluation based on  predefined criteria is performed by several business experts . Individual opinions are aggregated in order to get an average evaluation for each  scenario against each criterion.
Assess the level of agreement of the qualitative evaluation 
The discrepancy among individual evaluations is used to assess if there is consensus or not on the average evaluation of each scenario.
Choose preferred scenaria
The preferred set of scenaria is selected after performing a quantitative evaluation (for scenaria with low consensus) and a comparative evaluation.
