This phase is crucial. It is the difference between meaningless creativity for creativity's sake and real business results.
First, determine what will be involved in executing on a high-value scenario for achieving the purpose; then compare the various ideas generated in the creation session. Compare the ideas for:
Efficiency (use of resources vs. potential return – i.e., bang for the buck)
Feasibility - timeframe, costs, fit with a larger organizational picture, etc.
- Value created
Don’t stop after comparing a few; compare all of them. Then, when you have your choices narrowed down to one or a few, have a conversation to improve the conversation – what have we missed, how does one idea inform and improve others, etc.
Finally, commit to one plan and consider execution factors such as accountabilities, decision-making protocols, organizational needs, etc.
