What is SDLC?

SDLC, an acronym for Software Development Life Cycle, is the

universal framework used for developing softwares for various computer platforms. SDLC greatly helps software developers in meeting the various requirements of their valuable clients. It is equally useful for maintaining the cost-effectiveness of the software development program by keeping the budget in check.

Phases of the Software Development Life Cycle

SDLC has enjoyed a reign over the software development industry for many years and is considered to be a standard in itself. The software Development Life Cycle involves a number of phases, all of which play a key role in the development of the software. These phases are explained below:

PROJECT PLANNING PHASE + This is essentially a research stage of the product development life cycle. It requires software developers to conduct a preliminary study which helps them in assessing the practicality as well as feasibility of the product. Once these studies have been conducted and the underlying costs have been projected, they are conveyed to the client for review and approval.

SYSTEMS ANALYSIS PHASE + This stage requires the software developers to review a list of requirements that has been provided by the client. This phase is essential in three ways.

a.Firstly, it helps software developers in identifying any requirements that they will not be able to meet.

b.Secondly, the software development firm can also check if their computer systems and other resources are capable enough to fulfill the requirements of the project.

c.Lastly, It allows software developers to break down the software development process into smaller processes. This way, smaller goals and milestone can be set to track progress in the later stages.

SYSTEMS DESIGN PHASE + In this stage, the various functions of the computer systems along with other relevant information is discussed and detailed. Diagrams and charts of the project, laying down the rules of the business, planning screen layouts, and defining other relevant factors are all part of the systems design phase.

BUILDING PHASE + The building phase is the actual software development phase. A team of dedicated professional software architects set out to meeting the requirements of the client. The building phase is usually broken down into further smaller stages and each stage is assigned to different teams for completion. This ensures that every aspect of the project gets equal attention. The goals are also divided into milestones so that the progress of the entire project can be tracked with ease. The building phase also requires software developers to maintain a constant feedback loop with the client so that any hindrances in the development process may be promptly reported and a suggestion may be received.

Testing Phase + After the software has been successfully developed; the software development firm scrutinizes it for shortcomings or anomalies. Once the prototype has been approved by experts, it is ready to be used by the client and is delivered to them.

INSTALLATION + upon delivery, the software is ready to be installed into the client's computer system. Software development firms are almost always the ones who take the initiative of installing the developed software to the businesses computer system. Once the software has been installed, the client may bring it to the use of the business with immediate effect.

Maintenance

However, the job of the software development firm doesn't end here. The process requires good software development firms to maintain a feedback with the client just in case the software may develop a problem. In such cases, it is the duty of the software developer to guide the client on how to tackle the specific problem. In case the same problems keep resurfacing time and again, the software is handed back to the developers for revision.
