Software engineers use the software development life cycle (SDLC) framework to plan, create, test, and deploy software applications. The SDLC model provides a standard process for conducting these activities systematically and efficiently.

Several different SDLC models can be used, each with advantages and disadvantages. The most popular SDLC models are the waterfall model, the spiral model, the Agile model, and the DevOps model.

No matter which SDLC model is used, the goal is always to produce high-quality software that meets the customer’s or client’s needs. Therefore, we will provide a summary of the SDLC’s many stages and models in this article.

Defining SDLC

The software development life cycle of SDLC is the framework that helps organizations plan, create, test, and deploy applications. It is a process followed by software developers to create high-quality software products.

The current system development life cycle consists of seven key phases. It includes:

  • Planning stage

  • Feasibility tests or requirements of the analysis stage

  • Design and prototyping stage

  • Software development stage
  • Software testing stage
  • Implementation and integration
  • Operations and maintenance stage

SDLC helps lower the cost of software development, improves quality, and accelerates output. The SDLC accomplishes these seemingly incompatible aims by adhering to a strategy that eliminates the common hazards of software development projects. This approach starts by examining the current systems for flaws.

Then, the specifications for the new system are established. The software is then built using analysis, planning, design, development, testing, and deployment steps. SLDC can lessen the need for additional work and post-hoc fixes by anticipating costly errors like neglecting to acquire feedback from the client or end-user.

It’s important to realize that the testing phase is given proper attention. Since the SDLC is a systematic process, you must ensure code quality at every stage. Even while doing so could save them time, money, and rework, many organizations opt to put minimal effort into testing. A

The SDLC is a critical process for software development projects. It helps organizations ensure that the software products are high quality and meet the customers’ needs.

We will discuss in-depth the different stages of SDLC in the next section.

The Distinct Stages of the SDLC

Here are the various phases of the Software Development Life Cycle.

The Planning Stage

Before beginning the planning stage, it is necessary for the team involved in software development to spend time properly understanding the app development life cycle.

The planning or feasibility stage is where the software developers hatch the plan for the upcoming project.

Defining the goals for their new systems and the problem and the extent

to which the current system functions can help. At this stage, developers will identify issues before they can impact the whole project. Creating a strong outline can mitigate these potential issues for the future cycle.

It also assists them in obtaining the funds and materials needed to carry out their ideas.

The most crucial part of SDLC is the planning stage, where the software development team creates the project timeline. It will ensure that the commercial product will be released on the market at a specific date.

The Analysis Stage

All the information required for the new system is completed at this stage. It includes compiling the information and producing the initial prototypes for the concept.

At this stage, the developer would:

  • Identify all the system requirements needed for the prototype
  • Consider alternatives, if any
  • Determine the demands of the end-user based on the results of research and analysis
  • Producing the software requirement specification or SRS by the developers

It details every need for the system they want to develop, including software, hardware, and network requirements. It will stop them from using too many funds or resources while working alongside other development teams.

The Design Stage

The design stage is necessary before moving to the primary development stage. It outlines the specifics of the overall operation of the application and other particular features, including:

  • User interfaces
  • Device interfaces
  • Wi-Fi and other network needs
  • Databases

In the design stage, the software developers will transform the SRS document they created into a more rational structure that relates to computer language. Moreover, they would also align the operation plans, training, and maintenance at this stage to guide the developers in the succeeding stage.

Meanwhile, the development managers will devise a design document at this stage. It will serve as a guide in the next stages of the SDLC.

The Development Stage

At this stage, it is the programmers’ turn to construct the application codes according to the designed specifications and completed design papers. Here, they will also use SAST tools, or static application security testing.

All the same, they will create the program code based on the specifications in the design documents. Then, with the extensive planning and outlining completed in the previous stage, the actual software development process is simple.

The software developers will also use various tools like debuggers, compilers, and interpreters while adhering to the code standards specified by the organization. It includes standard programming languages like Java, Python, and many others. The programming language they will be using will depend on the needs and specifications of the project.

The Testing Stage

In creating software, having the product is not the end. It requires testing to guarantee that it has no defects and will not affect customer experience. Hence, software developers will thoroughly review this product in the testing stage. It will enable them to identify any flaws or defects that are not only corrected but also recorded and retested.

The final version of the program will get the nod if it adheres to the quality requirements stated in the SRS document. The length of the testing stage may vary depending on the expertise of the developers, the program’s complexity, and the end-users needs.

The Implementation and Integration Stage

The completion of the software design happens right after testing. Then, the developers will incorporate diverse designs and modules into the main source code. Usually, power users and training environments are used at this stage to identify more problems and flaws. Finally, all the information gathered during the implementation and integration stages will be built and integrated into its surroundings.

The program is technically ready for sale after clearing this stage and may be made available to any end customer.

The Maintenance Stage

The SDLC is not over when software is sold on the market. At this point, the developers will gear up for maintenance mode and perform the tasks necessary to address the concerns of the end-user. At the same time, developers are also ready to make any necessary modifications to the program after its deployment.

The maintenance stage may involve fixing the remaining flaws they can do before launching or resolving any problems end-users raise. Compared to smaller systems, larger systems could need more extensive maintenance phases.

Why is the SDLC important?

When the SDLC is done correctly, maximum management control and documentation level are implemented. It clarifies the purpose and function of what developers should create. It also ensures that all parties recognize the objective and have a specific plan for getting there. Furthermore, all stakeholders are aware of the expenses and resources needed.

The role of the product manager is to understand the client’s and the market’s needs and then translate those into a set of requirements for the development team. Next, the architect is responsible for designing the overall structure of the product, while the designers create the individual components. Next, the developers build the product according to the specifications, and finally, the testers verify that it meets all the requirements.

However, developing a product is not just a matter of following instructions. It is also a creative process, as new challenges and better solutions often arise during development. In addition, requirements frequently change as clients change their minds or the team’s understanding of the problem grows. As a result, product development requires a flexible approach to accommodate frequent changes. Furthermore, since most products are developed by teams of people who work independently, it is important to have a clear and well-defined process to ensure that everyone knows their role and how their work fits into the overall picture. By following the SDLC, product managers, architects, designers, developers, and testers can work together to create a high-quality product that meets all the requirements.

In software development, the software development life cycle (SDLC) is a series of phases that provide a common framework for understanding the process of developing software. Breaking down the development process into distinct stages allows for more effective communication between team members and stakeholders.

It also makes it easier to manage the development process, as each stage can be monitored and controlled independently. One model for the SDLC is the waterfall model, which progresses from one stage to the next in a linear fashion.

However, other models, such as the agile model, may be more suitable for certain projects. Ultimately, the choice of the SDLC model should be based on the project’s specific needs.

Many issues might make an SDLC implementation more of a hindrance than a benefit for development. For example, from the onset, poor knowledge of the system requirements might arise because of a failure to consider the needs of the customers, users, and stakeholders. However, a meticulously followed strategy that SDLC provides can prevent this.

To wrap things up

In conclusion, SDLC is a process that helps ensure that software is developed in a systematic and quality-focused manner. The distinct stages of SDLC ensure that various aspects of the software development process are carried out thoroughly and efficiently.
