What is Software Development Life Cycle, and what are the challenges at each stage of the SDLC?

The SDLC (Software Development Life Cycle is a framework) describes the various steps in software development. It covers the planning and deployment of the software. The SDLC framework defines the complete cycle of development for software products. This includes planning, testing, and deploying a product.

SDLC involves software development services that are typically long and tedious. However, with the right tools and resources, system analysts and project managers can easily manage the life cycle of their software projects. This lets them concentrate on their core business and deliver better quality software products.

What Exactly is a Software Development Life Cycle?

The concept of a software development life cycle is a project management framework that describes the various stages of a project’s development. It allows organizations to manage their projects from their conception to their final deployment.

Phases of The Software Development Life Cycle 

The other phases of the system development process are the design, prototype, testing, implementation, and maintenance phases. The planning phase is the most crucial stage of the system development process. It involves planning and designing a system’s architecture and requirements.


The Planning Phase

The planning stage is a process that involves planning for the development of a new project. It involves identifying the main problems and scope of the project, as well as developing the strategy and objectives for the new system.

Developing an effective plan for the next development cycle helps organizations identify potential problems before they affect the project. It also helps them secure the necessary resources and funding to make the plan a reality.


One challenge in the planning phase is understanding the app development lifecycle before you start working on a project. But once you have a clear grasp of the software development, this will allow you to make better decisions and enhance the efficiency of the project.

The Designing Phase

The design stage is a warm-up to the main development stage, and it involves gathering details about the application’s overall structure and features. Developers will then start working on the details of the application, such as its interface designs and network requirements.

What are the challenges?

Developers need to create a more logical structure for the program that will later be used in a programming language. This step will help developers keep track of all the steps in the development cycle. In addition to the document itself, they’ll also create maintenance plans and training programs to ensure that their teams are well-equipped for the future.

After completing the design stage, development managers will prepare a design document referenced throughout the SDLC’s subsequent phases.

The Testing Phase

After building software, it is now time to test it to ensure that it is stable and will not negatively affect the end-user experience. During the testing phase, developers will inspect the software to identify any defects and bugs that need to be fixed. This is, in fact, a crucial phase in SDLC. 

What are the challenges?

One of the most critical factors that a software developer should consider when meeting the quality standards set in the Software Requirements Specification (SRS) is ensuring that the overall design and development of the software are in line with the standards. 

Depending on the complexity of the project and the end-user requirements, testing can take a long time or be very short.

The Integration Phase

After testing, the overall software design will be completed. The software will be integrated into the device’s environment and will be installed.

What is the challenge?

This process usually involves integrating various design elements into the main source code, which is the fundamental element of a software or computer program. Once this stage is over, the software will be ready for market.

The Maintenance Phase

After the software has been launched to the market, the SDLC must transition into a maintenance mode. This allows the developers to perform various activities related to the issues that the end-user experience. Also, they are responsible for ensuring that the software’s changes are correctly implemented.

What are the challenges?

You need to handle issues that are not resolved before the launch of the app, as well as new ones that emerged due to user reports. Large systems, on the other hand, require more maintenance time. 

Final Thoughts

Software Development Life Cycle (SDLC) involves important phases to create a successful app or program. From the planning stage down to the integration and maintenance stage, it requires meticulous observations, activities, and more. 

However, in every stage, you may encounter minor to major challenges. But, with the help of software development services, you can minimize problems leading to the successful launch of your software.
