The SDLC is the foundation of all good, effective and efficient, development methodologies

What is the SDLC?

The SDLC is a system and software development life cycle approach for the development of systems, software, applications, and can also be used or modified for use in delivering infrastructure projects and programs. The SDLC is a model for the life cycle development and management of a system, product, software or application. SDLC is an acronym that is defined as the system development life cycle, although the software development life cycle can be defined within or outside of the System Development Life Cycle. That is sometimes why SDLC is identified and defined also as a software/application development life cycle (SDLC/ALM).

For the SDLC, an appropriate development methodology is determined/selected to be used for the project or program. The methodology may be traditional or Agile, or a combination of both.

Where does the SDLC begin?

The System/Software Development Life Cycle starts with the analysis and definition phases/processes, where the function of the system, product, software or application is determined. In determining a solution, the SDLC is determined to be the approach for the solution and an appropriate development methodology is selected to be used for the project or program.

How is the SDLC Used?

It sets the stage for a product/system’s implementation (the solution) through the development life cycle whether it is performed iteratively, sequentially or in parallel.
