Describe software project life cycle

This model is also known as verification and validation model. This model is the simplest model in its form. It requires little planning, lots of programming and lots of funds.

This model is conceptualized around the big bang of universe. As scientists say that after big bang lots of galaxies, planets and stars evolved just as an event. Likewise, if we put together lots of programming and funds, you may achieve the best software product. For this model, very small amount of planning is required. It does not follow any process, or at times the customer is not sure about the requirements and future needs.

So the input requirements are arbitrary. This model is not suitable for large software projects but good one for learning and experimenting.

In this article, we discuss the notion of software development life cycle, its phases, and common methodologies used in it. Software development life cycle SDLC is a series of steps that a team of software developers must follow to develop and maintain software.

A software development life cycle begins with a decision to build software and ends after removing that software from exploitation.

The software development process includes 5 key phases. Each of them contains several steps. Essentially, SDLC is a roadmap for software product development. Why is SDLC important?

From deadline breaches to rushed decisions and futile attempts to bring the project under control, poorly planned software projects tend to go out of hand. In contrast, having an outlined software development life cycle in place, businesses can have the bliss of a predictable software product development. For software developers , it means understanding what they do now and what comes next. Here are some key benefits of SDLC:.

Thus, all projects should have an outlined software development life cycle because it's the only way to ensure the resulting software will meet the demands of both business owners and end-users.

Goal: to gather and document business requirements. This step includes collection of requirements for software product development from stakeholders, industry experts, and even potential customers.

After that, the project owners outline the project scope, defining a budget, resources, deadlines, and potential risks and quality assurance requirements.

All requirements are encapsulated in a formal document, Software Requirement Specification. Project managers, business analysts, and software developers will refer to this document frequently.

Post the completion of various plans; risk management is carried out depending on the criticality of the project. Identifying the potential threats and analyzing the impact of such threats occur from the part of this sub-phase.

A risk management report is prepared with a plan to mitigate future threats. Done with the project idea finalization and planning. In this phase, previous planning is put into action. This phase depends highly on planning. Better the plan better will be the execution. Project managers follow the below steps in this process:. Here the entire team comes to the picture as it starts with actual work e. Daily targets are set; the team has to ensure to meet them; in case of delay, they have to report to project managers.

This phase is merged with the execution phase because both occur at the same time. The main objective here is to ensure that execution is carried out as per the plan.

Timelines and costs adhere.
