If you want to pursue a career in the SDLC field, you are in the right place! We are here to present the top and best interview questions and answers on the software development life cycle (SDLC). By the end of these questions, you shall be confident to face your SDLC interviewer.
Ans: The SDLC comprises six phases: The requirements phase, the analysis phase, the design phase, the coding phase, the testing phase, and the delivery and maintenance phase. The phases of software creation are fundamental to it as every step ensures the orderliness and effective production of soft wares. Let's check in a little detail on the respective operations of these stages:
1. Requirements Phase:
2. Analysis Phase:
3. Design Phase:
4. Coding Phase
5. Testing Phase
6. Delivery and Maintenance Phase:
Ans: In the first phase, the main task is communicating with the stakeholders to establish their needs. First, the leading players are the business analyst (BA), who collects requirements based on the provided company template, and the engagement manager (EM), who reviews these requirements and provides additional requirements.
Ans: The analysis phase is crucial as it allows for the detailed software requirements specification. It involves a detailed review of the initial phase and gathering requirements to build the software according to the customer’s wishes.
It ensures optimal resource utilization, enables stakeholder input during requirement adjustment, and provides a sound base for later improvement. It also gives a correct cost, quality, and time estimate and avoids scope creep. In addition, it promotes user centrism to increase the project's success.
Ans: This will focus on making software architecture in the design phase. It encompasses the creation of data flow diagrams, E-R diagrams, class diagrams, and object diagrams. This stage leads to TDD, which forms the Technical Design Output and becomes the coder's technical document.
Ans: In this stage, commonly called the Coding phase, programmers do the actual programming or coding. Using the Technical Design Document as a guide, they write the source code following appropriate coding standards, such as good indentation, color coding, and commenting. This is evident in the Source Code Document (SCD).
Ans: Test Engineers test the software during the Testing phase to ensure it satisfies the requirements. Considering the requirement document, they develop and implement test cases to ensure the software has no defects. A quality product provides proof for this stage.
Ans: The delivery phase involves transferring the application to the client. Installation engineers deliver and install the application in the customer’s environment and the original program software. The proof document is the final official agreement between the customer and the company.
Ans: Lastly, maintenance involves investigating the challenges the customer experiences when using the application after delivery. The third stage guarantees that the software continues to operate desirably and meets the user's changing needs.
Ans: It is a structured software development method that ensures each phase deals with certain aspects of software development, from requirement gathering to maintenance. A systematic approach assists in building high-quality software that conforms to customer needs and ensures reliability
Ans: Standards of coding like indentation, color codings, and commenting ensure the code's consistency, readiness, and maintainability. They are essential in teamwork between the developers and for any modification and enhancement in code for future reference.
Ans: TDD is a detailed document produced during the Design phase. This outlines the software architecture, including design components such as data flow diagrams and class diagrams. The source code development plan is an essential component of the Coding phase; this document plays a significant role for developers.
