Which SDLC phase involves the actual development of the system for in-house projects?

The phase of the Software Development Life Cycle (SDLC) that involves the actual development of the system is the Development phase. This phase is where the designs that were formulated during the Design phase are translated into the actual software code. Development involves programming, integration, and can also include activities such as code reviews and unit testing to ensure that the software is built according to specifications.

During this phase, developers use various programming languages and tools to create the software elements based on defined requirements. It is a critical stage because any errors or flaws introduced during coding can propagate into later phases, which may lead to increased costs and time to correct them later on.

In the context of in-house projects, the Development phase is particularly significant because it entails close collaboration between developers and other stakeholders to ensure that the final product meets the needs of the organization. The emphasis is on creating a functional system that can be further refined and tested in subsequent phases.
