Which SDLC model is considered the most effective?

According to the annual State of Agile report, Agile stands out as the superior SDLC methodology and is widely adopted in the IT industry. This is due to its amalgamation of incremental and iterative approaches, making it well-suited for adaptable environments. Nonetheless, it’s also important to choose the model that aligns best with your specific requirements.

What is Debugging?

Debugging, in the realm of software engineering, is the process of identifying and rectifying software bugs. In simpler terms, it involves locating, assessing, and fixing issues. Debugging becomes crucial when the software encounters difficulties in running properly.

What are the duties of a software project manager?

A software project manager oversees the software product management department. They are responsible for defining the specialization, objectives, structure, and expectations of the software product. Additionally, they lead activities such as planning, backlog refinement, stakeholder management, and also providing the necessary roadmap to develop the finest software.

What is a baseline in Software Development?

A baseline in software development is a significant milestone that signifies the completion or delivery of one or more software deliverables. Its primary purpose is to also reduce and control vulnerabilities or weaknesses in a project that could potentially disrupt progress and lead to unmanageable changes.

What is SRS?

SRS, or Software Requirement Specification, is a formal document that serves as a representation of software, enabling customers to evaluate if it meets their needs. It comprises a list of requirements for a specific software product, program, or set of applications designed to perform specific tasks in a particular environment. It also outlines user needs for a system, along with precise specifications for system requirements. Depending on the author, it also serves various purposes.
