What is the planning area of the Software Development Lifecycle (SDLC) also known as?

The planning area of the Software Development Lifecycle (SDLC) is referred to as Requirements Analysis. This phase is crucial as it involves gathering, documenting, and analyzing the needs and expectations of stakeholders for the software project. During Requirements Analysis, developers and project managers work to understand what features and functionality are necessary to meet user needs and business goals. This foundational step ensures that the project scope is clearly defined, which helps to prevent scope creep, reduces the risk of project failure, and lays the groundwork for the subsequent phases of the SDLC, such as design and development.

While terms like Design Specification, Pre-development Planning, and Feasibility Study are relevant concepts within the broader context of software development, they do not explicitly capture the focused scope of identifying and detailing requirements from stakeholders, which is the essence of Requirements Analysis.
