The word System Development Life Cycle or Software Development Life Cycle or SDLC is very familiar. But do you all know that along with you, some people can’t decide, which is the best SDLC among- Classic Waterfall Model, Evolutionary, Agile SCRUM, or other new models? The 7 phases of Software Development Life Cycle are planning, requirements, design, development, testing, deployment, and maintenance.

In this blog, we will cover:

  • What is Software Development Life Cycle?
  • Why SDLC?
  • 7 Stages of System Development Life Cycle
  • Take Away Points

Let’s take a look at SDLC.

What is Software Development Life Cycle (SDLC)?

SDLC is a process that a software organization follows for a software project. We can even say that it is a series of seven main phases to create software or hardware. This methodology aims to enhance the development process and the quality of the software.

7 Phases of software development life cycle:

  1. Planning
  2. Requirements
  3. Design and Prototyping
  4. Software Development
  5. Testing
  6. Software Deployment
  7. Operations and Maintenance

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.

An SDLC aims to allow the 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 stages of software development life cycle, which we will cover below.

Why software development life cycle?

SDLC gives a defined view of the entire system, resources, timeline, and goals. It 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.

The main reasons why SDLC is essential for developing a software system are:

  • Using the SDLC, it is easy to measure the growth and costs of the developed system.
  • SDLC enhances the control and monitoring of significant or complex projects.
  • SDLC involves well-detailed and comprehensive steps.
  • The design reviews help to ensure the reliability and quality of the developed solution.
  • SDLC provides extensive documentation of the system.
  • If a primary project member leaves, a new member can pick up where they left off.
  • It helps in evaluating, scheduling, and estimating deliverables.
  • It ensures correct and timely delivery to the client.
  • Provides a framework for a standard set of activities and deliverables
  • Improves development speed

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

From the 7 steps of SDLC , the first one is the planning step. In this 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, the three things that are mandatory to keep in mind are:

  • 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

Next in the System development life cycle is the requirement. The team ensures the project requirements of the end-users of the system. The company needs to connect with IT departments to express the new technology and improvement criteria.

Architects, developers, and product managers collaborate with SMEs to document the business processes that need software automation. This system development life cycle phase helps meet the client’s requirement by collecting the information on a single piece of paper and following it.

#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 / Software Development

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 enormous step of the SDLC.

Developers will obey specific 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 as software testing is necessary to avoid any bugs. The created software is extensively reviewed during this process, and any issues found are assigned to developers to repair them.

Retesting and regression testing are conducted until 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 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.
