The unique selling propositions of COMA are: Model quality and stakeholder buy-in.

Model quality

In a brown-paper session there are typically a few participants who take the lead in providing the input for the model, the others are thereby discouraged to contribute and their valuable input is lost.

In a COMA session everyone contributes as the methodology directly stimulates active work. This is achieved by making modeling enjoyable and by having working groups of two which encourages interpersonal discussions. As a result of that the total input is richer and the quality of the model is higher.

There are also other, more subtle mechanisms that increase model quality; e.g. the participants are more satisified with the modeling process and therefore put more effort into the model.

Stakeholder buy-in

As already mentioned, COMA participants are more active in the modeling process and hence feel more ownership of the model to which they all contributed significantly. COMA participants are also more satisfied with both the process and the result of it. Satisfaction and feeling of ownership together increase the commitment of the stakeholders to the model and its implementation in the organization.
