The pressure for sustainable, valuable investment in IT has been constantly increasing. And this, despite of an increasingly volatile business environment.

The challenge is therefore to ensure that only the requirements, that really add business value, are implemented.

An additional challenge exists when a common system should support different entities that were running separately similar processes.

Detecon's recommended approach is to first describe the end-2-end business use cases, to harmonize the business processes between different entities, and, then, to consider requirements based on the different steps of the business use cases. In some industries, a standard framework, such as eTOM in the telecom industry, exists and can be taken as basis for the definition of the company's business use cases.
