The Software Development Life Cycle (SDLC) is a methodology for developing high-quality software solutions.
SDLC is a Process to produce high quality software with lowest cost expenditure in minimum time.
SDLC Provides a structured and well defined phases that help to develop a high quality software in well tested and in ready to use condition.
The SDLC methodology focuses on the following phases of software development:
- Requirement analysis
- Software design such as architectural design
- Software development
Popular SDLC models include the waterfall model, spiral model, and Agile model.
Main purpose of using SDLC is lowering the cost of software development and at the same time providing the quality software product while minimising the development time.
The SDLC is a planned structure and moves step by step. The first step is evaluating.
Next step is requirement analysis. In this phase requirements of new system defines. After Requirements it goes through the different phases of development and testing.
The final phase of SDLC is deployment.By anticipating costly mistakes like failing to ask the end-user or client for feedback, SLDC can eliminate redundant rework and after-the-fact fixes. When you are going to search a JOB related to software development you must be familiar with the SDLC and SDLC Interview Questions and Answers as well.
Here we have listed SDLC Interview Questions that are asked frequently:
What do you understand by SDLC?
SDLC is short for the Software Development Life Cycle. It is basically a software development process, which provides a clear architecture or model for the management and creation of the software. It helps in strategizing our actions based on our desired plan.
What do you understand by Testing Phase?
When a model goes through various rectifications for the search of errors existing in the software. There are many techniques now for this particular phase and can be customized as per one’s needs.
What are the different types of SDLC methodologies?
The different models of SDLC are –
- Waterfall model
- Agile model
- Iterative or incremental model
- Spiral model
- Evolutionary prototype model
What are the phases in waterfall model?
Phase of waterfall model are:
- Requirements gathering
- Implementation & Maintenance
Where should we include the bug fixes in SDLC?
Bug fixes stage should also includes software maintenance.
What is CMM Maturity Level in SDLC?
The CMM (Capability Maturity Model) is a standard or benchmark which is used in the process of the development model in an organization to study or know the maturity of the processes being followed in an organization. The CMMI level is used to determine the quality or maturity of a software development process in an organization i.e. either software or hardware. It will be used to assess the organization on a scale of five different levels and the processes being followed in the organization. The five different levels are Initial, Repeatable, Defined, Capable (Managed) and Efficient (Optimizing).
What are LLDs or HLDs in SDLC?
The LLD (Low-Level Design) and HLD (High-level Design) are used to analyze and understand the project in a high level and low-level overview to different types of team members to the customers depending on the technical or business knowledge of the person. The Low-level Design is a detailed design implementation which will be helpful in the development process for the Developers whereas the High-Level Design will be given by Architects to proceed with the development process initially. This will be easier to know or look at a glance to understand about the project easily.
What are the processes included in Testing Phase?
Different testing methodologies are practiced detecting the software bugs, which happen to take birth during the previous phases. Today, there are many types o testing tools, and methodologies are available. Few firs are also building their testing tools, which are custom made as per the need or their organizations.
Here we have presented SDLC Interview Questions with answers. Hope this segment will help you to clear the Interview. If you have any SDLC Interview Question you can ask answer from us. All the best!
