Thema

Wissenschaftlich fundierte Argumente für agile Softwareentwicklung

  1. In a study of failure factors on 1.027 IT projects in the UK (only 13% didn’t fail), scope management related to attempting waterfall practices (including detailed up-front requirements) was the single largest contributing factor for failure, being cited in 82% of the projects as the numer one problem, with an overall weighted influence of 25%.
    We want the requirements to be stable, but they aren’t. Attempts to face this callenge by early detailed requirements analysis and freeze can rarely succeed, given the high rates of change. In the study of failure factors (...),
