The software development life cycle sdlc is a process used for structuring the development of any software system, from initiation through to implementation. This phase starts with the requirement document delivered by the requirement phase and maps the requirements into an architecture. Various phases of software development life cycle sdlc are. The architecture defines the components, their interfaces and behaviors. A common misconception among business owners is that the most important stage of software development involves the design and the code. Analysis is about truly understanding the problem, in depth. Once the analysis is complete, the step of designing takes over, which is basically building. Key phases of software development projects written by irma azarian on july 30, 20 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. All these questions are answered in the technical design phase. Later, in the design phase, the very important decomposition of the problem leads to the development of data structures and algorithms. Write a note on software design phases computer notes. Software design should be traceable to the analysis model. There are several phases in the sdlc, and the requirements gathering and analysis phase is the first phase.
