In the seventh and final phase, end users can fine-tune the completed system as necessary if they want to improve performance. Through maintenance efforts, the team can add new capabilities and features and meet new requirements set by the client. Phase 6 begins when a huge part of the program code is completed. This phase also involves the actual installation of the newly-developed application. The project is put into production by moving all components and data from the old system and putting them in a new one through a direct cutover.
Phase 4 represents the real beginning of software production and hardware installation (if necessary). It’s worth noting that goal-oriented processes do not adhere to a one-size-fits-all methodology. Instead, they are highly responsive to user needs and continuously adapt—the main reason why teams require a well-defined plan to improve the quality of the system at each phase of the life cycle. The most flexible of the SDLC models, the spiral model is similar to the iterative model in its emphasis on repetition. The spiral model goes through the planning, design, build and test phases over and over, with gradual improvements at each pass.
Phase #6: Deployment
This model emphasises interaction, as the customers, developers and testers work together throughout the project. By breaking the product into cycles, the Agile model quickly delivers a working product and is considered a very realistic development approach. But the risk you run is creating a never-ending spiral for a project that goes on and on. Waterfall is the oldest and most straightforward of the structured SDLC methodologies — finish one phase, then move on to the next. What was your best or worst, or both kinds of software development experience? Looking at this question asked on StackExchange, you will know that several experts believe that the Waterfall model was never meant to be a real, working SDLC methodology for developing software.
- These six phases map to behavior you might already be implementing when scoping, building, testing, and releasing software.
- Adhering to the SDLC methodology helps to optimize the final outcome.
- It is vital to have as diverse a team as possible during this phase.
- Because this document determines all future development, the stage cannot be completed until a conceptual design review has determined that the system specification properly addresses the motivating need.
- Each iteration of the spiral model builds on the previous one and reduces the overall project risk.

Customers in remote rural areas are finding difficulty to access the bank services. It takes them days or even weeks to travel to a location to access the bank services. By making access to scientific knowledge simple and affordable, self-development becomes attainable for everyone, including you!
During these phases architects, developers, and product managers work together with other relevant stakeholders. By adding new steps, developers could define clearer and more effective actions to reach certain goals. Think about my prior examples with time tracking software development. For example, if you strive to build software designed for hourly employees, as Zoomshift has done, or time tracking software, you would start at the “requirement analysis” stage. The six phases seek to build on each other in an efficient manner to answer questions and to ensure alignment in your development process. A bit of an anomaly among SDLC methodologies, the Big Bang model follows no specific process, and very little time is spent on planning.
Start Managing Your System Development Life Cycle with a Helpful Template
Developers use the methodology as they design and write modern software for computers, cloud deployment, mobile phones, video games, and more. Adhering to the SDLC methodology helps to optimize the final outcome. 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. Regardless of the process implemented and the tools used, all require the crucial element of documentation to support findings, close iterative phases, and to analyze success.
