SDLC Interview Questions and Answers

Question: Explain the phases in a typical SDLC process briefly.

• Planning: The first stage of the SDLC is all about determining, what clients want. Project planning is an important component of the software delivery lifecycle because it is here that the team estimates the cost and outlines the new program's needs.
• Gathering Requirements: Defining requirements is part of the planning process to figure out what the application is supposed to perform and what it needs. The development team examines the requirements while keeping the software's design and code in mind.
• Design: The following phase entails distilling all of the software project's requirements, analysis, and design information. This phase is the culmination of the previous two, such as customer feedback and requirement collecting. It is a simulation of how a software application will work. Some particulars of this phase are architecture, platform, security, and user interface.
• Development: This is where the code is really written. Writing code is the first step in putting a design into action. Developers must adhere to the coding requirements set forth by their bosses. Many other jobs are included in the coding process. Many developers need to brush up on their abilities or collaborate with others. It's vital to find and resolve problems and flaws. If any changes or upgrades are needed, the developers can show the work to the business analysts.
• Testing: Before making an application available to users, it's vital to test it. The testing team examines the system's overall functionality. This phase aids in reducing the number of faults and issues seen by consumers. As a result, there is a higher level of user satisfaction and a higher rate of utilization.
• Deployment: Once the product has been thoroughly tested and is ready for deployment, it is made available to customers. The deployment's complexity is determined by the project's size. Many businesses prefer to have the deployment step automated.
• Maintenance: The developed product is looked after throughout this period. The program is updated on a regular basis to keep up with the changing user-end environment or technology. Users find flaws that were not discovered during testing. These issues must be addressed, which may result in new development cycles.
