The successful development of these simulations is aided by attention to sound software project management and software engineering. We have developed \u201clessons learned\u201d from a set of code projects that the Department of Energy National Nuclear Security Agency has sponsored to develop nuclear weapons simulations over the last 50 years. We find that some, but not all, of the software project management and development practices (rather than processes) commonly employed for non-technical software add value to the development of scientific software and we identify those that we judge add value. Another key finding, consistent with general software industry experience, is that the optimal project schedule and resource level are solely determined by the requirements once the requirements are fixed.<\/jats:p>","DOI":"10.1177\/1094342004048534","type":"journal-article","created":{"date-parts":[[2004,10,26]],"date-time":"2004-10-26T06:29:03Z","timestamp":1098772143000},"page":"399-416","source":"Crossref","is-referenced-by-count":53,"title":["Software Project Management and Quality Engineering Practices for Complex,                 Coupled Multiphysics, Massively Parallel Computational Simulations: Lessons Learned                 From ASCI"],"prefix":"10.1177","volume":"18","author":[{"given":"D.
