Incremental development for AXE 10

To become more reactive and flexible to the market needs, i.e. shorter lead-times and more flexibility in handling late and changing requirements, Ericsson’s AXE 10 development processes have been adapted to support incremental development. The basic principle is to develop each of the customer features in one executable and testable increment. In order to plan, coordinate and control projects executed in this way, an Incremental Development Method Package, IDMP, has been developed by UAB in close cooperation with support groups in development projects. In this paper, we define what we mean with incremental development and describe the main aspects of the package. We also report experiences from using the package in the CMS 30 phase 7 and HELIOS projects. A prototype tool which supports the package is described, together with the experiences from using the tool in the pilot project Combined Gateway. Even if the IDMP has been developed towards AXE 10, it has proven useful in non AXE 10 projects, as the principles are rather independent of development process.
