7 Phases of the System Development Life Cycle Guide

The Development stage involves the actual coding and programming of the system. Based on the design specifications, developers write code, create database structures, and implement necessary functionalities. Rigorous testing and quality assurance are performed to ensure the system’s accuracy, performance, and adherence to the design requirements. In fact, each organization may develop its own list of tasks, techniques, and (automated) tools, which can be referred to as “their” methodology.

• In this guide, we’ll break down everything you need to know about the system development life cycle, including all of its stages.
• The final phase of the SDLC is to measure the effectiveness of the system and evaluate potential enhancements.
• SDLC offers standardized and planned processes for all phases of the system development.
• The project’s specifications and intended results significantly influence which model to use.
• In most use cases, a system is an IT technology such as hardware and software.
• Once the required function is done, an analysis is complete with auditing the feasibility of the growth of a product.
• Requirements Gathering – provides alternative means to illustrate, explain, and specify exactly what must be delivered to meet business goals.

This stage seeks to address various defects in the system with specific suggestions for enhancing the system. Once the requirement analysis is done, the next stage is to certainly represent and document the software requirements and get them accepted from the project stakeholders. The Information Security Manager must ensure that the required security features are included in the system. These standards should be used within the context of the Forensic Laboratory’s Secure System Development Life Cycle. They are designed as a checklist to ensure that proper attention is given to all aspects relevant to the secure implementation of developed software.

I.A.2. Systems Development Life Cycle

Systems analysis and design (SAD) can be considered a meta-development activity, which serves to set the stage and bound the problem. SAD interacts with distributed enterprise architecture, enterprise I.T. Architecture, and business architecture, and relies heavily on concepts such as partitioning, interfaces, personae and roles, and deployment/operational modeling to arrive at a high-level system description. This high-level description is then broken down into the components and modules which can be analyzed, designed, and constructed separately and integrated to accomplish the business goal. SDLC and SAD are cornerstones of full life cycle product and system planning.
