System development can be broken down into phases that help define and develop the software. The planning stage defines the scope and objectives of a new system or upgrade to an existing one. It also catches potential problems before they begin development. This stage can also set a project schedule, which is particularly important when a product is commercially viable. The analysis stage involves gathering specific details, gathering ideas for prototypes, and assessing the final functionality. Developers often create a software requirement specification (SRF) that will outline the requirements of the project.

The design stage incorporates all the system requirements and creates a logical structure. This stage of development is also known as “requirements validation,” and it helps avoid the overdrawing of resources. The development manager will then prepare a design document, which will be referenced throughout the rest of the SDLC process. This document will also help maintain the functionality of the system. In addition to the SRS document, the development manager will also prepare a training and maintenance plan.
The design phase comes after understanding the requirements of the customer. This phase identifies the necessary elements of the system, including its architecture, modules, and data. This phase can also include a master document and flowcharts. A flowchart can effectively represent an algorithm, and the developer can discuss the steps with end users. The design phase of the system development life cycle will help the client clarify the project and the business refine requirements.
