One of the biggest problems of creating a good business model lies in the initial stages of model development cycle. The initial stages of business modelling methodologies are concerned with two tasks.
The first is the specification of the requirements for the system.
The second is the construction of an initial business model; this model is often called an essential or conceptual model and is built out of the set of the domain specific objects known as essential or conceptual objects.
We must not forget that both these tasks should be carried out with the active participation of the stakeholders, in order to ensure that the correct system is being developed. Consequently, any tools or diagrams used at these early stages should be meaningful to the stakeholders, because many of them are not “software engineering literate”. Finally, these diagrams must not deform or inadequately simplify the requirement information.
