What is the Software Development Lifecycle (SDLC)?

0

In today’s digital age, it’s bewildering how many software development initiatives are implemented on an ad hoc basis, which almost always results in poor quality results. Creating a software product from scratch without any systematic framework is virtually guaranteed to lead to project budget overrun, late delivery, or failure to meet end user / customer expectations. It can even cause an entire project to fail.

The Software Development Lifecycle (SLDC) offers a better solution. SLDC is a systematic process used by software development companies to create the highest quality software in the shortest possible time. The process usually follows one of several methodologies, such as:

There is plenty of evidence for its effectiveness in the software industry as it meets customer expectations and meets completion dates and costs within budget.

How the SDLC works

SDLC helps eliminate common problems and pitfalls associated with software development. Thus, it automatically shortens the time consumption of software developers, improving product quality while lowering labor costs.

The SLDC process includes well-defined steps necessary for software development. Here are seven major phases of development:

1. Planning

In the start-up phase, the terms of the project are determined by the project managers. Everything is calculated here, from the creation of teams and structures to the final material costs. Its purpose is to clearly define the goals and objectives of the application. Feedback from stakeholders is also crucial in this phase.

2. Define the requirements

Phase two creates a clear vision of what the application needs to do and what compliance requirements it needs to meet. It also includes identifying the resources needed to complete a project.

3. Design the product

Once the software specifications have been developed, it’s time to turn them into a design plan. Then, stakeholders can review it in depth and provide feedback. Phase three also defines the architectural components of the products and how they are interconnected.

4. Build the product

Here the whole product development process begins and the product is created. Organized and detailed design will ensure that the whole process takes place with minimal deviation. So every developer should make sure the proper guidelines are in place and then stick to the plan.

5. Product testing

When running a software project, never underestimate the power of testing. It is also important to note that this phase is included in all other SDLC phases. Through testing, each function should be examined to make sure everything is working properly. Here, defects are identified, analyzed, resolved and retested until the product meets defined quality standards.

By testing using project management tools, you will reduce the number of errors and issues before you bring the product to market, which will increase customer satisfaction and uptake rates.

6. Deployment of software on the market

The product is released to the production environment during the deployment phase, so the app is now available to users. Most companies deploy their products in multiple areas and use automation for deployment. Automation can be as easy as downloading the app to a smartphone.

7. Maintain

Software support / maintenance includes the following aspects:

  • Bugfix
  • Performance improvement
  • Code optimization
  • Support for the latest versions of the operating system
  • Implementation of additional features
  • Support for the latest versions of third-party services

The main point of this phase is to ensure that customer needs continue to be met and that the system continues to operate according to the specifications established in the first phase.

Conclusion

SDLC structures the phases involved in software development and does not end until all stages have been successfully completed. The most visible benefit of the SDLC process is that it provides control over the development process, ensuring that the software system meets all estimated requirements. It is important to note that SDLC may not work well for software projects that include a lot of uncertainty or no chance to add creative input. However, for almost all other scenarios, if the developers follow the customers’ requirements and adhere to the detailed plan, SDLC will prove to be an invaluable resource in creating the highest quality software in the shortest time possible.
