Similarly to any software development project, the job of implementing a software product is tiered and complex. To make things more difficult, these stages or tiers modify as per the repeatability and priority, thereby creating the models of software product development lifecycle.
Various existing SDLC models address the individual and diverse circumstances of the development vendors and product owners, but such a great pick might be confusing. Of course, a company that offers software development services can pick an SDLC model themselves.
