SDLC Interview Questions and Answers

Ques 6. Explain the types of SDLC models.

The following are the predominant models that come under SDLC:

    Waterfall model: The waterfall model is a prominent software engineering and product development approach that takes a linear, sequential approach to the software development life cycle (SDLC). The waterfall approach emphasizes a logical step-by-step process. It was the first model in the software business to be extensively adopted. It is divided into phases, with one phase's output becoming the input for the next.
    Agile model: Agile approaches divide jobs into smaller iterations or sections and avoid long-term planning entirely. The scope and requirements of the project are defined at the start of the development phase. The number of iterations, duration, and scope of each iteration are all clearly determined ahead of time. In the Agile process model, each iteration is a small-time "frame" that lasts anywhere from one to four weeks. 
    Iterative model: One of the most straightforward software development life cycle models is the iterative approach. There are several situations when the initial or basic software requirements are well-defined, but the project's complete scope or set of features is unclear. It primarily focuses on preliminary growth and design, then gradually develops momentum as more complex needs are met until the final software is completely constructed. 
    Spiral model: The spiral model is a risk management strategy that combines the iterative development process model with parts of the Waterfall approach. The spiral approach is preferred by software engineers for large, expensive, and complex projects.
    V-model model: The V-model is an SDLC paradigm in which processes are executed in a V-shape in a sequential manner. The Verification and Validation model is another name for it. The waterfall model is extended by the V-Model. Every phase of the development cycle has a testing phase that is directly linked to it.

Ques 7. Which SDLC model is best and Why?

According to the annual State of Agile report, Agile is the best SDLC methodology and also one of the most widely utilized SDLC in the IT industry. Unlike other predictive approaches, the adaptive agile methodology does not necessitate comprehensive preparation. If a change is required, it can be made during the sprint. It's ideal for projects that require a lot of customer involvement and projects that have a constantly changing environment.

Ques 8. What are the advantages of the SDLC process?

At the end of each stage, a formal review is established to provide maximum management oversight. SDLC aids in the creation of extensive system documentation. This guarantees that system needs can be linked to specified business goals. It generates a large number of intermediate products that may be evaluated to see if they fit the user's requirements and adhere to industry standards. These can be improved further if necessary, ensuring that the company receives exactly what it requires.

Ques 9. What are the disadvantages of the SDLC process?

Before you begin, make sure you understand all of the details of the project. During the development phase, there was a lot of paperwork. It is difficult to alter or change due to a lack of flexibility. If the planning isn't done properly, the project will take longer and cost more. When there are a lot of flaws in the code, fixing them can take a long time and cause deadlines to be missed.

Ques 10. List Top SDLC tools.

  • Jira: This software is intended to make workflow management easier for a wide range of groups. Jira was created with the intention of being a simple system for recording tasks and errors. However, it has since matured into a robust workflow management solution.
  • Git is a distributed version management system that is open-source. Developers aiming to examine changes and contributions to the overall code might considerably benefit from a version control system or VCS. This software customization management tool is an important part of the SDLC.
  • Confluence: During this stage, Confluence is a wonderful tool for developing product research docs and sharing design assets.
  • Asana: From daily activities to larger projects, Asana assists teams in orchestrating their work. Teams are more confident, move faster, and accomplish more with less when they use Asana, regardless of where they are based.
