In this era of digitalization, we cannot imagine our lives without technological innovations. Each activity of humans is integrated with some kind of computer-related procedure. Software development is an extensive process that has various key steps known as the software development life cycle. The software and applications which facilitate your daily functioning are produced by a development team.

The software development life cycle teaches a set of techniques, methods, and rules to the software development team. It helps to link the tech, non-tech team members, and the stakeholders of a project to transform the ideas into actions. By knowing the key steps required to develop software, the development teams know how to meet the project requirements, deadlines, and stay within the budget. Each step of the software development life cycle depends upon the final prototype of the software development process. The model may be agile, incremental, RAD (Rapid app development), or waterfall.

7 stages of the system development life cycle

Here are 7 stages of the system development life cycle :


The creation of software initiates the process of planning or thinking of an idea. But implementing the idea cautiously is the main aim of the software engineers. This is one of the most crucial steps of the software development process because it helps to determine the scope of the project, its aim, and defines the system to meet the business objectives. The developers can create a planned draft that consists of resource availability, cost-related issues, budget, timeframes, and determining solutions. Creating a perfect and detailed plan will help you in the later stages of the development process.

Requirements analysis

After planning about the various needs, a requirement analysis is conducted to substantiate the project’s feasibility. Before creating an actionable solution and appealing design of the software, the development team must know the requirements of the project goal.

Feasibility analysis helps to have cognizance of various technical and economical aspects that can impact the development process. These aspects entail time, resources, and estimated products of the development team like ROI or project, cost, and profit. With the help of the requirement analysis, the software engineering team can also know the threats or the possible risks to the business and can formulate strategies to minimize them.


Software design determines the final product created by the developers of the system life cycle. In this process, the detailed software architectural knowledge is used to create the software according to the project requirements. The software architects create customized software designs that help them to set definite workflows and standards.

In this stage, the entire structure of a project is created with the final prototype. It consists of defining the functionality of the solution, fundamental hardware or software components, structural capabilities, and the processes to meet the objectives of the business. Once the design is completed, the software developers move forward to the next step, which involves actual development.

Coding and development

In this phase, the developers write codes relevant to the software and then convert it into actual software. The development and coding are the longest, most crucial, and extensive processes with various substeps. The software development team makes sure that the code created aligns with the requirements and specifications of the clients. If the previous stages of the software development life cycle were paid heed to, then this stage is likely to proffer good results. The testing stage initiates after the developers create the architect of the solution 


The testing and integration phase starts and the processes used in the phase may vary according to the prototype. Generally, the software developers integrate a range of frameworks alongside executing various unit tests, automation, compilation, and testing. Various tests conducted by the quality assurance team include system integration testing, interoperability, acceptance testing, etc. Substantiating the code helps to achieve the business goals without suppressing any errors. Integration and testing is a crucial stage that helps to make the software bug-free and initiate the implementation stage.


Implementation refers to a step by step procedure that helps in the actual installation of the designed solution. The newly created application is then moved to a production where the data and components are transferred. There are two types of releases based on the complexity of the project. A state forward release encompasses a simple project and a staggered release is in the case of a complex project. After the software is released, users can use it to their advantage and make their activities simpler.


Once the software is created, the developers need to maintain it with regular updates. This is one of the most crucial phases because it helps to refine the software development tools according to the dynamic trends of the environment. Moreover, upgraded and enhanced software is always at an advantage over the competitors’ products. The developers need to bolster the functioning of the application, upgrade its performance, and modify it according to the changed needs of the users.

The software development life cycle is a complex process that differs from company to company. This is because the customers have different requirements which the software developers should aim to satisfy. The software development life cycle is a general process that can be modified according to the needs of the particular project, app development software provider, or according to the actions and the goals of the business.

It is a basic foundation needed to rearrange the framework and helps the team members to understand the technical and non-technical activities required to deliver a quality product according to the particular codes. By knowing the various stages of the software development life cycle, software engineers can meet the expectations of the clients through effective decision-making skills.

At the end of the day, the final product, which helps the users and increases their satisfaction is what matters. By knowing the key steps to develop software, you can create good quality software that helps to augment the cooperation level of your client. With this, he or she may hire your services again for the next project.
