In this rapidly digitising world, technology has a big impact on our daily lives. Everything today is digital. It’s no surprise that almost all businesses and companies, including well-established enterprises, rely on Custom software development and Custom Software Development Lifecycle to take their business to the next level and operate online.

Custom software is developed for companies according to their specific requirements and unique needs. The development of custom software that fulfils particular needs and features of the company follows a specific cycle known as the Software Development Life Cycle (SDLC).


In this article, we dive into the process and stages of the software development lifecycle and its importance in the custom product development industry.



What is a custom software development lifecycle (CSDLC)?

The custom software development lifecycle refers to the process of creating custom software and its maintenance. The software development lifecycle is a 5 stage process which plays a key role in product making and its delivery to ensure that the end product suits the requirements of the company.

These stages streamline the process of product development by aligning several factors like deciding budgets, quality assurance, demands, UI UX design, deployment and launch of the product. Various companies use different types of lifecycle models like agile development, waterfall, RAD, and V-Model. 

Why is SDLC important?

Many IT software development companies prefer SDLC. The SDLC is Cost-effective and time-efficient which helps in product making and delivery for the IT companies. The ultimate goal of the Software development lifecycle is to minimize the risk for the product in product development and also help in future planning to meet the expected requirements.


SDLC helps in defining the structure and steps of product development and does not conclude until every step is fulfilled. The key advantages of SDLC are quality assurance, Risk management, Cost control, Time management, Customer satisfaction, Scalability and maintenance. The most important advantage of the SDLC lifecycle is that it gives us control over the process to some extent and ensures that the end software satisfies all specified requirements.


Custom Software Development LifeCycle Stages:

1. Ideation and Planning: 


Every project needs a solid idea and to execute the idea successfully planning is very crucial for every project. That is the reason the first step in the software development lifecycle starts with Ideation and planning. This step not only gives us an idea about the client’s visions but also gives us the power to plan and execute them according to the tailored needs and requirements of the client.


At this step, we understand the client’s business needs and requirements. We thoroughly study and research the business of the client, analyse the business process, identify pain points, and decide the goals and targets of the business It also involves selecting the right methods to implement, analysing the available resources, identifying the challenges which may come, estimating the project’s size, and most importantly estimating its cost.


Feasible analysis: 


Requirement Gathering: 


  • At this stage, we gather all the necessary information about the client’s unique needs and requirements. It ensures that the software developers and designers get the proper idea of the client’s vision and execute the product accordingly avoiding any discrepancies.


Requirement Analysis:


  • After all the necessary information has been gathered in the first step, the information should be analysed in the following step by the developers.


  • The team members creating the software must take their time to develop ideas for the project’s functional and technical components.


  • Team members then analyse how achievable the requirements are to remove any unwanted thing in the plan.


2. Design


Once the project planning and ideation are done we can now start designing the product according to the client’s needs. This step involves creating wireframes and prototypes to get a better understanding and visualization of the user interface of the project and its functionality. At this stage, we improve the design and functionality of the product by taking the client’s feedback and requirements before moving to the development stage. 

The software structure and its architecture depend on the Software requirements document to prepare design documents.


These are: 


  • SDS (System Design Specification), which features a physical design.
  • DDS (Design Document Specification) features a physical design.


These documents include most of the designs that include metadata, Data flow diagrams and many more.


3.  Implementation and Development: 


The coding phase is the foundation of software development. At the point when design elements of the software development cycle are complete, the DevOps team will set up the servers and the software developers will start writing the code. The Development team will write the source code and will also integrate APIs into the application from the backend to meet the functionality and design requirements set out in SDS and DDS.


Development teams use programming languages, programming frameworks and best practices to build the core functionality of the software. Developers also need to keep in mind the demands and unique needs of the clients. Once the design has been developed and the functionality of the software has been set, the custom software product will now enter the testing phase.



4.  Testing and Deployment:


During the testing phase of the software development Lifecycle. The Tester will test the product to see whether it is working or not as intended before releasing the software. To do this the tester will write down the test cases and test scenarios and will start executing the test accordingly. From here, the tester will start validating all the requirements and make sure everything works as expected. 


The testing is usually a loop. When the developers finish coding and test coding for its functionality. Then the code goes to the tester and the tester uses the different frameworks and white or black box technique to test the product at each level. In-house testing, module testing, user-end testing, and program testing are some types of testing performed by expert testers to ensure the product is bug-free, flawless and has a very smooth flow. If the product has bugs and errors the software is sent back to the development mode that’s why we say testing is a loop. 


When the coding is completed and the integrated software elements are functional. Then the software is now installed on the cloud for the client to use and for feedback. Once the software is deployed it is available for the end users.

5.  Launch and Maintenance: 


The launch and maintenance are the final step of the Software development lifecycle. Once the software has been thoroughly tested and approved by the client. It is ready to be launched for the targeted users. After the launch maintenance is provided by the development company the development team maintain the server and makes sure the system remains healthy and functional. The team also fixes future bugs and updates the software with new features.



In conclusion, the software development Lifecycle is a systematic and efficient way to create custom-made software which ensures the unique business needs and requirements of the client. Following the five stages of CSDLC minimises the errors and bugs, controls costs and promotes long-term scalability. Selecting a Custom software development company which aligns with the SDLC lifecycle is very crucial for a successful project.
