However, developing high-quality software applications is a complex and challenging process requiring much effort and work. For every software application development, its completion in a pre-defined time and budget is equally important as ensuring its quality. To achieve this, you should work in an organized and structured manner to keep track of the progress in software development. The high competition puts huge pressure on the software organization to develop bug-free applications. Most organizations are turning towards Software Development Life Cycle as it offers a systematic process for developing software applications.

However, it is important to note that Software Development Life Cycle may not be the one-size-fits-all approach. They require to be adapted to fit specific software application requirements. With the high demand for speed and agility in the development process, a shift from the older Software Development Life Cycle (Waterfall Model) to DevOps emerged. With this, security is now considered a critical component throughout the SDLC. While there are many best practices in development, some myths persist. It is not always essential to switch to a new methodology unless the product, project manager, or stakeholders specifically require it.

This process is used to plan, design, schedule, test, and deploy the release. Versioning helps ensure the integrity of the production environment when upgrades are deployed. Rapid development cycles help teams identify and address issues in complex projects early on and before they become significant problems. They can also engage customers and stakeholders to obtain feedback throughout the project lifecycle. However, overreliance on customer feedback could lead to excessive scope changes or end the project midway.

In other words, the entire development of software applications is broken into small application builds, known as iterations. To develop highly functional and optimized software applications, it is essential to have a robust plan and design strategy. Post that, using the SDLC approach in development can be an appropriate option.

Phase 1: Requirement collection and analysis

This is one of the most critical stages because it’s when your hard work gets put to the test. This phase often requires extensive programming skills and knowledge of databases. The team will build functionality for the product or service, which includes creating a user interface and building the database so users can store information in your system. Software development life cycle (SDLC) is the term used in the software industry to describe the process for creating a new software product. Software developers use this as a guide to ensure software is produced with the lowest cost and highest possible quality in the shortest amount of time. If you begin developing a new product and software as a startup, it’s important to follow the life cycle of the system development for a great impact and effectiveness.

Following the best practices and/or stages of SDLC ensures the process works in a smooth, efficient, and productive way. This SDLC model is documentation-intensive, with earlier phases documenting what need be performed in the subsequent phases. After evaluating all the possible factors, the most practical and logical design is chosen for development. Hence, once the purpose and specification of the application are created (Design Document Specification-DDS), the developer moves to create the project design. Further, each cycle of respective iteration develops on others and easily deploys when the software build is completed. It may also be helpful to choose your first software language to learn.

New to software development?

Because many teams immediately test the code they write, the testing phase often runs parallel to the development phase. The system development life cycle framework provides a sequence of activities for system designers and developers to follow. It consists of a set of steps or phases in which each phase of the SDLC uses the results of the previous one. The waterfall model provides discipline to project management and gives a tangible output at the end of each phase. However, there is little room for change once a phase is considered complete, as changes can affect the software’s delivery time, cost, and quality.

In this method, every cycle act as the maintenance phase for the previous software release. Modification to the incremental model allows development cycles to overlap. After that subsequent cycle may begin before the previous cycle is complete.

Here, the logical design of the software application is converted into the physical design. On completion of the requirement analysis phase, now it’s time to decide how the development process of the software application will take place. It includes planning an objective, the pathway to reach it, things to be done, etc. In simple terms, planning is all about deciding on the distribution of time, resources, and efforts.

• Developers are now responsible for more and more steps of the entire development process.
• Iterative Model comprises small repetitive iterations, which involve repeating a series of steps until the expected software application is developed.
• For example, the GitHub platform scans code for security issues as it’s written in the coding phase.
• This model works best for small projects with smaller size development team which are working together.
• As an experienced software development company, we know the importance of SDLC and how it allows developers to create custom software with proper structure and methodical way.

Therefore, the model is most suitable for small software development projects, where tasks are easy to arrange and manage and requirements can be pre-defined accurately. The traditional Project Management (waterfall) approach is linear where all the phases of a process occur in a sequence. The approach depends on predictable tools and predictable experience.

SDLC provides a well-structured flow of phases that help an organization to quickly produce high-quality software which is well-tested and ready for production use. Once the software testing phase is over and no bugs or errors left in the system then the final deployment process starts. Based on the feedback given by the project manager, the final software is released and checked for deployment issues if any. For this, developers use a specific programming code as per the design in the DDS.

Further, you should consider that the Waterfall Model can be expensive and does not provide a way to make new changes. Therefore, it is always advisable to go through the requirements and complexity of the software application before choosing the SDLC model. There are many different models software development life cycle definition of the Software Development Life Cycle through which software development can be done. If you haven’t yet started your journey as a software developer, you might ask yourself, “Is software development for me? ” Here are some signs that this career path might be one that you will enjoy.

It’s also important to know that there is a strong focus on the testing phase. As the SDLC is a repetitive methodology, you have to ensure code quality at every cycle. Many organizations tend to spend few efforts on testing while a stronger focus on testing can save them a lot of rework, time, and money. In this life cycle model, the system is partitioned according to areas of functionality. Each major functional area is developed and delivered independently to the client. For example, in the bike hire system, tasks relating to issuing a bike might be developed and delivered, followed by returning a bike and then maintaining customer records.
