Instead of a customer there's a community which containes mostly software developers responsible for joining in projects as a developer or as a tester. The people within the community are situated worldwide, as with the developers joining a project. This geograhical distance can influence the progress of the project over time in a negative way..
Looking at this scenario 3o Group tried to come up with a non commercial development method where the priority lies at implementing standards for designing, coding and planning.
Please feel welcome to give critisism about the concept.
