Stages of Software Development Lifecycle using a waterfall approach In the waterfall approach, each stage of the project delivered is a set of tasks that have to be completed by a planned deadline. A common set of stages for a software development project are [1]: System requirements Software requirements Analysis Program design Coding Testing Operations (until the system reaches its end of life - EOL) In theory, after the requirements are gathered, and the system was designed, implementation has to satisfy the requirements and the design without the possibility of changing the agreements made during in previous phases. Each phase is a silo of work, which is disconnected from other silos . This can result in a situation of conflicting requirements being detected during the testing or deployment phase without a chance to discuss these requirements with their authors. Maintenance is a special type of stage because there are cases when it is unknown, how long the system will be maintain
