How you do software engineers?

Answer 1

There are two general approaches to engineering software. Both have to do with how software projects are managed. One approach is called the Waterfall approach. The other is called the Agile approach. In the Waterfall approach, the project moves through a series of stages. These are conception, requirements analysis, design, programming, testing, and delivery/deployment/distribution. A project timeline gets developed in which the time for each stage is estimated, and deadlines for each stage are set. Often a certain amount of extra time is added for unforeseen events. In the Agile approach, a periodic cycle is set up, generally between two and six weeks per cycle. During each cycle, most of the stages of the Waterfall approach get done to the extent that time allows. So in each cycle the team does analysis, design, programming, testing, and demonstration to the customer. At which point the next cycle begins by asking the customer what part they need to have done next. The Waterfall approach is good when what is needed by the customer (requirements) is well understood up front, and is not likely to change. The Agile approach is good when either what is needed by the customer is not well understood (even by the customer), or requirements are likely to change during the course of the project.
