Software development life cycle examples

The software development life cycle (SDLC) describes stages of software development and the order in which these stages should be implemented. Each stage produces deliverables for the next one.

Every SDLC contains the following stages:

  • Defining the project scope. After a customer and a vendor initiate a project, the project manager on the vendor’s side assigns the project team. Together with the customer, they define the project scope through requirement gathering and analysis.
  • Development. At this stage, the developers prepare a system design and define the overall system architecture. The PM decides on the software development approach and pricing model. Then, the project team gets down to implementing and integrating the required features.
  • Stabilization. Now, testing engineers check the software to ensure that its quality is acceptable and the product serves the intended purpose. The developers fix bugs.
  • Delivering product to the customer. After testing and bug fixing, the final version of the software is delivered to the customer.
  • Maintenance and support. The project team takes care of the developed product even after its release, improving it upon the customer’s request and continuously troubleshooting the product.

These illustrative software development life cycle examples show that the customer can get a high-quality product meeting their expectations provided the project team follow SDLC. Defining project scope correctly is of critical importance in the project flow as developers should understand what they are expected to build and create a clear plan how to do it. Neglecting the customers’, stakeholders’ or users’ needs can result in a project failure. At the beginning of the development stage, the project team chooses a software development approach and pricing model. After they have implemented and integrated all the required features, testing engineers assure the quality of the software. After the software is delivered to the customer, the developers continue maintaining and supporting the delivered product or solution.
