This standard provides the set of Activities that constitute the Processes for the development and maintenance of software, whether stand-alone or part of a system. (Non-software activities, such as hardware development and purchasing, are outside the scope of this standard). This standard also provides associated Input and Output information. The proposed revision will differ from the original as follows: (1) The word process will be downplayed, or order to better focus attention on the Activities. Collections of Activities will now be called Activity Groups. (2) All Planning Activities will now be collected into a single Activity Group called Project Planning Activities. (3) The Verification and Validation Process will be replaced by a new Activity Group entitled "Evaluation Activities", which will include specific V&V Activities such as reviews, audits, testing.
