The Phases of Software Development Life Cycle you should know 

Each software development company follows the SDLC or software development life cycle. To develop a product, mobile application, or cloud platform, a software developers team invests its expertise in software development in all major languages. The process is followed throughout the life cycle of software, carefully considering the needs of the customers and consumers. 


Software Development Lifecycle

The Software Development Life Cycle is the formal process of manufacturing software that systematically verifies the quality and performance of software as per standards set by the industry and the company. It is the life cycle that ensures the correctness of the software being developed in the sector following the customer’s expectations. One factor to consider is that the manufacturing of the software must be kept in the agreed time and decided cost. 


Precisely, the cycle follows a compilation of ideas and plans explaining the whole process of planning, building, and maintaining the software from the initiation to the compilation process. The process is not stagnant and demands careful work at each step as various deliverables and processes require detailing throughout the life cycle phase. 


Why do Businesses require SDLC?

Businesses nowadays require SDLC for obvious reasons in the software production process. The life cycle provides the basis for the planning, scheduling, and estimating of the project. It also helps in project tracking and control with enhanced development speed. A standard set of deliverables and activities is devised through an efficient tracking system. Moreover, improved client relationship is achieved with the phases of software development life cycle.


Phases of SDLC

The entire process of the software development life cycle is explained in the following stages.


The Planning Phase 

In the first phase of the Software development life cycle, the expert software developers get to work. This process is initiated by gathering all the necessary tools to meet the software or project’s scope and demands. Moreover, the software development team tracks time, tools, resources, and capital contributions to the project success, also termed as feasibility report. Further, in the same phase, our company’s business software and business capabilities are tested. 


Draft of Requirements

Secondly, it is essential to note the project requirements. In this phase, the company connects with the IT team to express improved criteria and new technology. The developers, product managers, and architects collaborate with software developers to list the business processes requiring software automation. The client requirements are processed thoroughly throughout the SDLC.


Designing & Prototyping Phase

Once the project requirements are noted, the process of designing follows. The company’s software architects and developers begin with designing software. Moreover, the proven methodologies are applied to save issues with algorithms. The design process is accompanied by rapid prototyping and requires comparing the most suitable solutions. 


Software Development

The most critical phase of coding begins with the completion of the designing phase. All the developers get down to code the entire system with a pre-selected programming language. Moreover, all the team members are assigned tasks, with developers tracking their goals and milestones being achieved. Developers use the programming tools named debuggers, interpreters, compilers to build and execute code throughout the software development process. 


Testing Phase 

Post coding process comes in the testing phase. Testing is run with the modules set for the evaluation process to steer clear bugs. The bugs are assessed and forwarded to the developers for repairs through the continued testing process. Moreover, the retesting and regression process is executed to meet the customers’ expectations. The life cycle process reviews the software development making sure it is as per the consumer needs. Here, the coding and testing process is finalized. 


Deployment Process

In the final stages of the life cycle process, the motto is to deploy the software to the manufacturing environment, so the product is put to customers’ use. Although, most companies prefer to run the software through the delivery environment as a staging and testing area. The process allows stakeholders to check and verify the operations of the software before actually delivering it to the market. Thus, all the mistakes or bugs are tracked and treated before the product’s final launch. 


Final Operations and Maintenance

The SDLC process ends with the operations and final maintenance being done. Moreover, the software is updated and modified to adapt to the current changes. Each software development company follows SDLC phases to mark success in the software market. 



SDLC is a complex process of software development providing a complete view of the system, resources, timeline, and goals. The process allows advanced control and documentation throughout the development process. Companies offering SDLC services know their job. A plan is viewed, designed, tested, deployed, and managed carefully. Likewise, SourcingSquare being a software development company, owns a team of professionals working on software projects for stakeholders worldwide.
