The first step the development team should do before they even engage in writing the code is to collect all functional requirements to assess the scope of work and project cost. As part of this process, labor and material costs are calculated, a timetable is developed with goals, and teams and leadership structures are created for the project.
This stage helps to outline the team’s course of action and provide the tools and resources they need to effectively develop the software. Additionally, it helps prevent the project from expanding or diverging from its original goals.
This is a very important step when all the requirements should be defined. By the end of this phase, the team clearly understands what the software is meant to do and what features should be included. In addition, this SDLC stage is critical as it allows developers to find out more about all possible roadblocks that the project may face along the way.
Once the requirements are understood, an SRS (Software Requirement Specification) document is created. It is important that both developers follow the guidelines in this document and the customer reviews it for future reference.
Design and architecture are crucial when it comes to the software development process regardless of the size of the future software. Most SDLC methodologies attach great importance to this particular phase as it defines what the app will look like and how secure it will be for end users. During this stage, the team brainstorms the following aspects:
This is when the development process actually begins. It is possible to write a small project by a couple of developers, but a complex project may require the involvement of several teams.
In addition to coding, there are many other tasks involved. It is crucial to find and fix errors and glitches. Some tasks like test results or compiling code to run an application slow down the development process. The SDLC can anticipate these delays, allowing development teams to focus on other tasks.
No software leaves the lab without being thoroughly tested. The testing activities are usually included in all stages of the modern SDLC models, so this stage is usually a subset. However, this phase only relates to the product’s testing step, during which bugs are discovered, reported, fixed, and retested until the product meets the SRS’s quality criteria.
It is now time to deploy the software into production so that users can begin using it. Many companies, however, move the software through different deployment environments, such as staging or testing. In this way, stakeholders can safely test out the product before it is released to the market. It also allows identifying final bugs before a product is released.
The development cycle is almost complete at this point. The application has been completed and is now in use. However, maintenance and support still play an important role. Users may find bugs at these stages that weren’t discovered during testing. Resolving these errors can create new development cycles.
Besides bug fixes, models like iterative development plan additional features for future releases. There can be a new development cycle launched for each new release.
The software development life cycle adds value to the software development process in many ways. In particular, teams can benefit from the following advantages:
Before we put a full stop to this article, there are some best practices of software development that may be useful to you. The most popular approaches include:
Innowise Group uses all the benefits and best practices of this approach, which allows us to have better management control over the entire development process. Moreover, SDLC brings clarity of requirements and single vision of the product by all the involved parties, which, in turn, saves time and effort during development, testing and deployment stages. With software development life cycle we have more predictable results in terms of time and deliverables.
