This case study analyzes the development of an IT equipment and facility reservation system for King's Own Institute's (KOI) library. The report explores the application of the Software Development Life Cycle (SDLC) methodologies, specifically contrasting predictive and adaptive approaches, with a focus on the selection and justification of the Agile methodology. It details the requirement gathering process, including the use of surveys and interviews to collect data from KOI staff and students, and outlines both functional and non-functional requirements for the system. The functional requirements encompass aspects such as authentication, business rules, and data security, while non-functional requirements address system effectiveness, reliability, and flexibility. The study also provides a graphical representation of the facility reservation system. The document serves as a comprehensive analysis and design of a library reservation system, offering valuable insights into the development process.
