Ascentiv uses a software development process with the following focus: Incremental and iterative approach Test driven development Each customer has a clear vision about the business cases the software system should cover. During the concept phase, Ascentiv gathers requirements from a user perspective in close cooperation with the customer. We often use GUI prototypes to verify the requirements. A detailed and binding cost estimate results at the end of the concept phase. A stable base line architecture has to be established before we can start the first iteration of the implementation phase. Before a software release is approved and deployed to the customer, a successfull system test has to be conducted. At the customer, the software is rolled out in close coporation with the customer`s IT departement. Many of our customers safeguard their investment with a support contract.
