SDLC: 7 Stages Of System Development Life Cycle

The Software development life cycle (SDLC), also referred to as the System development life cycle, is a process for planning, creating, testing, and deploying an information system. Here we’ll talk about what is SDLC and 7 Stages of System Development Life Cycle.

The SDLC concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both. There are usually six stages in this cycle: requirement analysis, design, development and testing, implementation, documentation, and evaluation.

It is important to develop a plan of action to reduce delays and meet deadlines. In order to succeed in this competitive environment, businesses need to ideally develop their applications, using 5 effective software development methodologies, processes, and strategies.

The goal of an SDLC is to allow successful production of a high-quality solution that would meet or exceed the requirements of a customer at all its phases, within the provided budget and timelines. Whenever anyone starts developing a new product, it’s necessary to follow the SDLC stages.

7 Stages of System Development Life Cycle (SDLC)

Now let’s discuss all 7 phases of System development life cycle which every software developers follow to develop the perfect software.

#Stage 1: Planning

In the planning step, we are putting together all the tools to consider the scope and gravitas needed to pursue the software or project we want. The awareness of our customer’s requirements and how much capital, time, and resources we can contribute to their product’s success is also known as a “feasibility report”. And when we are in the preparation process, three things must be kept in mind:

• Identification of the system for development
• Feasibility assessment
• Creation of project plan

Furthermore, in this phase, we also weigh in on our options to see whether starting the development of a software or program is worth it to their investors or business as a whole. It also serves as a phase to assess our company’s business and software capabilities.

#Stage 2: Requirements

The company needs to connect with IT departments to express the new technology and improvement criteria.

Architects, developers, and product managers are collaborating with SMEs to document the business processes that need software automation. For a Waterfall project, the output of this step is typically a document listing certain requirements. In comparison, agile strategies can generate a backlog of tasks to carry out.

#Stage 3: Design and prototyping

Developers and software architects start designing the software after they have identified requirements. Developers apply proven methods for developing software to solve algorithmic issues.

Often rapid prototyping is included in the design process too. This approach requires a comparison of the best-suited solutions.

At the end of this phase, teams get design documents with the patterns and components chosen for the project, and the code used as a point of departure for further development.

#Stage 4: Coding

When the design process of the software is over, the next step will be the coding. In this step, developers start constructing the whole framework using the programming language chosen to write code. Tasks are divided into units or modules in the coding process and allocated to the specific developers. Coding is the largest step of the SDLC.

Developers will obey certain predefined coding guidelines during this process. They will also use programming tools such as compilers, interpreters, debuggers to build and execute the code.

Stage#5: Testing

When the coding is complete, testing begins and the modules are released for evaluation. The created software is extensively reviewed during this process, and any issues found are assigned to developers to repair them.

Retesting, regression testing is conducted until such time as the software is as planned by the expectation of consumers. Testers refer to the SRS document to make sure the software conforms to the customer’s standard.

#Stage 6: Software Deployment

In this phase, the goal is to deploy the software to the manufacturing environment so that consumers can start using the product. Many software development companies, however, prefer to push the product across different delivery environments such as a testing or staging area.

It enables every stakeholder to play with the product safely before it is introduced into the market. Therefore, this allows us to catch any final mistakes before launching the product.

#Stage 7: Maintenance

When the software passes through all the stages without any complications, a maintenance cycle is to be performed in which it is updated and modified from time to time to adapt to changes.

Every best software development company follows the stages of SDLC processes, resulting in the country’s success in the software market today.

Benefits of Software development life cycle (SDLC)

SDLC gives a defined view of the entire system, resources, timeline, and goals. SDLC can allow the highest level of management control and documentation. Software developers understand what they should build and why. Both stakeholders decide upfront on the target and see a concrete plan to achieve the aim. Everybody knows the necessary costs and resources.

Here are some benefits of SDLC are given below:
