A software life cycle is a model of the activities and work products necessary to develop a system. A methodology is
a collection of methods and tools for developing a system and specifies when methods or tools should be used and
what to do if unexpected events occur. Methodologies and life cycles are complementary: a software life cycle can be
realized using a variety of software engineering methodologies. Although specific methodologies may imply a
specific life cycle, in general, a methodology can be applied in a different life cycles.
Examples of life cycles: Boehm’s spiral model, the Unified Process, the Waterfall model.
Examples of methodologies: Royce’s unified framework, Extreme Programming.
