This paper examines the importance of using a System Development Life Cycle (SDLC) methodology in information systems projects. It argues that the SDLC provides a structured, sequential approach that prevents critical steps from being overlooked, ensures feasibility is assessed before development begins, aligns design with user needs, and guarantees thorough testing after implementation. The paper walks through each major phase — from identifying system necessity and requirements analysis to architectural design, coding, and system testing — explaining how each stage contributes to a more organized, cost-efficient, and functional final system.
The System Development Life Cycle (SDLC) offers a methodological approach to information systems design that ensures no critical step will be overlooked in the complex process of developing a new system. It ensures that the proposed design is necessary, will meet the needs of the users, and is properly planned, checked, and screened for problems before the final planned design is activated. Additionally, the use of the SDLC ensures that systems testing will occur even after the design is complete.
First, the initial step of the SDLC process identifies and defines a need for the new system and ensures that a rigorous inquiry will take place to answer the question of whether a new system is actually necessary, feasible, and useful to the users of the current system. Once that need is determined, the requirements analysis phase analyzes the information needs of the users so that designers can create a blueprint to effectively meet those needs.
The architectural design step of the SDLC process then creates a proposed design with the necessary specifications for hardware, software, personnel, and data resources. This further ensures that the approach will be as organized and as cost- and time-efficient as possible when the subsequent step — coding, debugging, and programming the final system — is carried out.
Finally, the process concludes with system testing, which evaluates the system's actual functionality in relation to its expected or intended functionality ("SDLC," Webopedia, 2006).
