Software development is an exacting process. One inherent risk is building an application that does not meet the customer’s expectations. In order to minimize this risk, a methodology needs to be in place to drive successful project results.
Software development methodologies evolved out of the Software Development Lifecycle (SDLC). The phases of the Software Development Lifecycle are as follows: Specification => Analysis => Design => Implementation => Testing => Maintenance
In traditional development methodologies, the phases of the development lifecycle are done in strict succession, where each phase must be completed before the start of the next phase. For instance, all of the business requirements are exhaustively gathered and documented before any analysis and design can begin. This approach is tedious and prone to problems, since software requirements are likely to evolve during the project.
Another common problem with the traditional approach is that a disconnect can occur between the customer’s expectations and the developer’s interpretation of the requirements. In many cases, the unfortunate outcome of this scenario is software that looks very different from what the customer originally intended.
Agile to the rescue!
The Agile software development methodology (Agile) is a flexible and adaptive approach to software development which emphasizes iterative development, incremental delivery of working software, and close customer collaboration to ensure the success of the project. In an Agile project, software is developed incrementally during brief periods called iterations, which are commonly referred to as sprints. At the end of each sprint, working software is delivered to the customer for testing, evaluation, and feedback.
The ultimate goal of any software development project is to produce software that satisfies the customer’s needs, which is the reason why Onix has adopted the Agile methodology for all of its development projects. Agile allows functionality to be developed quickly, since every last requirement of an application doesn’t need to be known before development can begin. Agile also provides the flexibility needed when requirements evolve or change. In an Agile project, the customers can see the progress of development every couple of weeks, instead of waiting until the end of the project to see the final result. Ultimately, frequent customer feedback ensures changes can be made quickly without impacting the project timeline.
