The software development life cycle sdlc can be defined differently by any organization, but it usually consists of the following activities that work together to mature a concept into a software product.
In the second set of four steps, the same events occur that occur in mitosis. After going through this lesson, students will be able to define key terms dealing with the process, meiosis and describe the main events in each phase of meiosis. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Mitosis can proceed independent of ploidy of cell, homologous chromosomes behave independently meiosis can only proceed if the nucleus contains an even number of chromosomes diploid, tetraploid. In the planning phase, project goals are determined and a highlevel plan for the intended project is established.
