What is Software Development Life Cycle (SDLC)?
Want to understand the IT industry and its processes better? Let's have a look at SDLC.
Requirements Gathering
Firstly, we define the customer's requirements to develop a product as per their expectations. A Business Analyst(BA) and Project Manager(PM) usually set up a customer meeting to gather all the information like what the customer wants to build, who will be the end-user, etc.
Analysis
The team determines the timeframes, resources and costs required to implement the analyzed requirements. PM and BA should evaluate the project's feasibility and how they can implement it successfully with the lowest risk in mind.
Design
After that, the design phase kicks in. The team makes design decisions regarding the solution architecture. It can involve creating design documents, coding guidelines, and discussing the tools, practices, and frameworks that will help to meet the set goals.
Development
What is next? Let's create what we want. Front-end, Back-end, and Full-stack Engineers start actual development. They work closely with UI/UX designers helping to create better user experiences. This stage of work ends once teams have packaged their code.
Testing
Before product release, we need to check if everything meets the standard for quality and performance. Software testing usually involves manual testing of user journeys and automated one based on engineering tools. If they find bugs, testers document them and inform the team.
Deployment
The next stage is deploying the software to the production so that users can start using the product. Systems (DevOps) engineers ensure that the software works the same way in the live environment as it does in the development & testing ones.
Maintenance
The plan rarely turns out perfect when it meets reality, so it's time to go to the final phase. It ensures that the application continues to run as intended in terms of functionalities and performance. Users, support team, and ongoing testing may uncover new bugs or security issues not found before that should be fixed.
