The SDLC field is one of the promising careers & has plenty of opportunities. If you’re considering a job in this industry, this article is just for you. We have compiled a list of the top 7 SDLC interview questions for you in order to help you crack the interview.
Question 1: What is the Software Development Life Cycle?
A Software Development Life Cycle (SDLC) is a well-defined process for creating high-quality, low cost software as quickly as possible. The goal is to develop great software that exceeds all requirements and expectations from customers.
Question 2: What are the phases in the Software Development Life Cycle?
The 1st Phase is about understanding the requirements of the client. This analysis is important because it helps the team estimate the costs associated with the whole program.
The 2nd step of the Software Development Life Cycle is to figure out the precise purpose & requirements of the Application. The development team considers these specifications while keeping in mind the software’s coding & layout.
This phase is the combination of the previous two. It is a simulation of how a software will operate. Some specifics of this phase are architecture, platform, security & user interface.
Once the analysis and designing choices are completed, it is time for the team to carefully create algorithms for implementing the program code. It is one of the time consuming phases where the team writes the actual code.
Before moving to the final stage, the team conducts a testing phase to verify if the code matches the defined product requirements. Various manual (penetration) testing and automation testing are done to examine the software. The testing gets completed when the software is free of bugs and capable of meeting quality standards. If the test shows an error they again have to create new, accurate software.
It’s now time to deliver the product to its end users so that they can start using it. Most companies prefer to deploy their product to 10-20% of the users at the 1st stage so that they can identify bugs / loopholes (if any) & find solutions accordingly.
The SDLC doesn’t end here. Based on the client reviews, the team has to timely respond to any flaws & update them based on user feedback. The team commonly has to check the following activities at this phase:
- Bug fixing
- Continuous Monitoring
- Timely upgrading apps to a new version
- New and interactive add-on features
- New & Interactive UI
Question 3: What are the Advantages of Software Development Life Cycle
- More visibility for the development team to analyze
- Better communication between the development team and high level
- An improved UX due to fewer bugs and errors
- Less chance of cyber attacks
- Less chance of project failure
- In-depth understanding of customer needs
- Less chance of data corruption and damage
- A better plan for data recovery and disaster
Question 4: Define Software Requirement Specifications
Software Requirement Specifications is a document that outlines the goals and functionality of the software. It is a formal report that enables clients to determine whether SRS satisfies their needs. Product functionality is also highlighted in this report in order to meet the needs of the stakeholders.
Question 5: Define Capability Maturity Model (CMM)
The capability maturity model is a criterion that assists organizations to lay a successful foundation to improve the process of software development. This methodology is implemented to enhance the quality of SDLC Testing and deliver the best to the end users.
Question 6: What are some of the best SDLC Tools
- Jira – This software is created to identify errors and tasks that has evolved into a powerful workflow management solution.
- Git – This is a customizable open-source software. It helps developers to easily evaluate the changes & contributions made into the code.
- Confluence – This is one of the most astounding tools that assist in development of product research and easily share design assets.
- Asana – Asana is a simple & flexible tool that helps you plan, organize the project so that the team works faster with more confidence & achieve their goals.
Question 7: What is the difference between quality control and quality assurance
- Quality control is the process handled by the dedicated support team to ensure proper product quality is maintained in every phase of software engineering.
- Quality Assurance on the other hand is handled by the project’s testing team to ensure the delivery of the product with fewer errors and defects to end users.
