SDLC Interview Questions and Answers

Following are the five Capability Maturity Model Levels:

• Initial: The first step is to create an unstable process environment. The software development process is considered haphazard and even chaotic at times. There are few methods that have been specified, and success is based on individual effort and heroism.
• Repeatable: Work is planned and monitored, making it repeatable. To track cost, schedule, and functionality, basic project management techniques are implemented.
• Defined: This level encompasses written and defined standards that evolve over time and support consistent performance. The work is well-defined at this point.
• Managed: Extensive data on the software development process and product quality are gathered. Both the software development process and the end products are quantified and managed.
• Optimized: Work is based on continuous improvement (optimization). The focus on continuously improving process performance is a significant feature of this level.

Scrum is an agile development approach based on iterative and incremental procedures that are used in the creation of software. It's an agile structure that's adaptable, rapid, flexible, and excellent at delivering value to customers throughout the project's development. Companies of all sizes employ the Agile Scrum technique because of its ability to provide high-end cooperation and efficiency for project-based work. Scrum is a sort of agile approach that breaks projects down into manageable parts known as "sprints." The Agile Scrum methodology is ideal for companies who need to complete projects fast.

Obstacles or challenges that the scrum team faces slow down their work speed are referred to as impediments. An obstacle is anything that tries to prevent the scrum team from getting work "Done." Impediments can take many different forms. Some of the roadblocks include resource shortages or sick team members, technical, operational, and organizational issues, a lack of management support systems, and business issues.

The Software Project Manager is in charge of seeing the project through to completion. The Software Project Manager is responsible for ensuring that the entire team follows a methodical and well-defined approach to software development. They also handle project planning, tracking project status, resource management, and risk management.

The process of tracking and regulating changes that occur during the software development lifecycle is known as software configuration management. Any modification made during the development of software must be tracked using a well-defined and controlled process. Any modifications performed during software development are regulated through a well-defined process, thanks to configuration management. Revision control and the establishment of baselines are two SCM procedures.
