Introduction

The Systems Development Life Cycle (SDLC) is a structured approach used in the development of information systems, ensuring systematic planning, development, and implementation. Good planning and execution of SDLC phases are crucial to delivering high-quality, effective, and sustainable information systems. This paper reviews the SDLC methodology by creating a visual diagram tailored to a specific scenario, elucidating essential elements across the lifecycle phases, and integrating scholarly sources to support the approach.

Scenario Analysis and Solution Formulation

The ISM500 SDLC Diagram Scenario involves a company aiming to develop an enterprise resource planning (ERP) system to streamline operations. The scenario requires designing an SDLC diagram reflective of this purpose, with each phase aligned to necessary resources and activities. The goal is to craft a comprehensive, logical progression that facilitates system development, implementation, and maintenance effectively.

SDLC Diagram and Phases

The SDLC typically comprises six phases: Planning, Analysis, Design, Development, Testing, Deployment, and Maintenance. These phases are interconnected, with clear inputs and outputs guiding each step. In the planning phase, project goals, scope, and resources are defined. During analysis, detailed requirements are gathered. Design entails system architecture and user interfaces. Development involves actual programming, followed by testing to detect also resolve software defects. Deployment makes the system operational, and maintenance ensures ongoing support and improvements.

Using visual tools such as flowcharts or diagrams helps clarify the sequential flow among different phases (Satzinger, Jackson, & Burd, 2019). An SDLC diagram for the ERP system scenario maps each phase with corresponding activities, resources, and deliverables.

Key Elements in Each SDLC Phase

- Planning: Project charter, stakeholder analysis, resource allocation, timeline estimates.

- Analysis: Requirements documentation, feasibility studies, needs assessment.

- Design: Data models, system architecture diagrams, interface specifications.

- Development: Coding standards, development environment, technical documentation.

- Testing: Test plans, testing tools, defect tracking systems.

- Deployment: User training materials, deployment plan, change management procedures.

- Maintenance: Support logs, system updates, user feedback mechanisms.

These elements are integrated within each phase to facilitate a smooth transition from one stage to the next, ensuring that each component aligns with overall project objectives.

Fit of Elements within Lifecycle Phases

The elements identified are integral to their respective phases. For example, requirements documentation during analysis informs system architecture design; coding standards during development promote code consistency and quality; testing tools enable defect detection, reducing post-deployment issues. The alignment of these elements ensures cohesive workflow, accountability, and traceability throughout the SDLC.

Scholarly literature emphasizes the importance of comprehensive planning and clear documentation for project success (Basili et al., 2018). Furthermore, iterative validation during testing and deployment phases enhances system reliability and user satisfaction (Avison & Fitzgerald, 2019).

Conclusion

The SDLC provides a disciplined framework for developing complex information systems like an ERP platform. By creating a graphical diagram and mapping key elements to each phase, developers and project managers can ensure systematic and efficient progression from concept to operation. Embedding credible sources supports best practices, fostering successful project delivery, and maintenance.
