The Trilinos Software Lifecycle Model

The Trilinos Project is an effort to facilitate the design, development, integration and on-going support of mathematical solver libraries. Efforts range from research and development of new algorithms to proof-of-concept of new and existing algorithms to eventual production use of solver libraries on a variety of computer systems across a broad set of applications. Software quality assurance and engineering (SQA/SQE) play an integral role in the project. Although many formal software lifecycle models exist, no single model can address all Trilinos developer needs since our requirements for rigor change as a particular Trilinos package matures. In this report we present a three-phase promotional lifecycle model that closely matches the needs and realities of Trilinos development.
