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.
