SDLC can be defined as the processes of chalking out an efficient software development strategy keeping in mind the time and resource constraints.

Depending upon the nature of client request or the problem in hand, the type of SDLC model being adopted varies but overall the basic steps involved in every other SDLC remains the same.

In the current era of cut-throat market competition, most of the top-notch software enterprises adopt suitable SDLC models to create high quality software within the required time and budget. An SDLC is formulated to facilitate development, altercation or maintenance of existing or new software.


SDLC is involved in every single aspect of software creation from start to finish. Hence its prime objectives are as follows:

  • Minimising the risk of project failure to a minimum.
  • Thoughtful consideration of the data and system requirements throughout the lifespan of the software.
  • Properly address the management and technical issues.
  • Evaluate the technical feasibility of the software.
  • Maintain regular information flow to back up the technical, management, time and cost of the proposed software for imminent development or upgrade.
  • Conduct periodic evaluation of the software to prevent it from being obsolete according to the latest market or user requirements.
  • Constant evaluation of the project status to rectify it as and when required.
  • Assist efficient resource and budget planning.
  • Consider the current and prospective software requirements.
