Introduction

The selection and application of a suitable System Development Life Cycle (SDLC) model are crucial to the successful completion of a software project. For this paper, I will select the Waterfall model, one of the most traditional and linear SDLC approaches, due to its structured and disciplined methodology. The project in focus involves developing an integrated inventory management system tailored for small to medium-sized retail businesses, leveraging my previous exploration of Information Technology (IT) specializations. This paper will define the Waterfall SDLC model and methodology, then align its phases with the specific components of the inventory management project.

Definition of SDLC and Methodology

The SDLC is a systematic process that guides the development of software applications from inception to disposal. It ensures structured progress through distinct phases such as planning, analysis, design, implementation, testing, deployment, and maintenance (Satzinger, Jackson, & Burd, 2015). The methodology applied within the SDLC provides a framework for executing these phases, dictating how tasks are performed to optimize quality, efficiency, and control.

The Waterfall Model and Its Methodology

The Waterfall model is characterized by a sequential flow where each phase must be completed before the next begins. It emphasizes thorough documentation, fixed requirements, and formal review stages (Royce, 1970). The phases include requirements gathering, system design, implementation, testing, deployment, and maintenance, with clear deliverables at each stage. This approach suits projects with well-defined requirements and low likelihood of significant change.

Application of the SDLC Model to the Inventory Management System

1. Requirements Gathering (Analysis Phase)

This initial phase involves collecting detailed requirements from stakeholders, including retail managers, inventory staff, and system administrators. It includes defining system functionalities such as stock tracking, order processing, supplier management, and reporting capabilities. Given the predictability of the inventory system, a comprehensive requirements analysis aligns well with the Waterfall's emphasis on fixed specifications.

2. System Design (Design Phase)

The design phase translates requirements into detailed architectural and technical specifications. It includes creating data flow diagrams, database schemas, user interface mockups, and application architecture plans. The design closely follows the documented requirements, ensuring that subsequent development implements the intended features and functions.

3. Implementation (Coding Phase)

This stage involves actual coding based on the predetermined design specifications. Developers utilize programming languages suitable for enterprise applications, such as Java or C#. The code is written in modules that correspond to different system components, allowing systematic development aligned with the design documents.

4. Testing (Verification Phase)

Testing includes unit testing, integration testing, and user acceptance testing (UAT). Each component undergoes verification to ensure adherence to requirements and functioning as intended. Issues identified are documented and rectified before progressing to deployment. The structured nature of the Waterfall model ensures comprehensive testing before moving forward.

5. Deployment (Implementation and Deployment Phase)

Once testing concludes successfully, the system is deployed to the production environment. This involves installing the software, configuring hardware, and training users. A thorough deployment plan ensures minimal disruption and facilitates smooth transition from manual or legacy systems.

6. Maintenance (Post-Deployment Phase)

After deployment, ongoing maintenance includes bug fixes, updates, and adaptations based on user feedback. Maintenance ensures the long-term viability and efficiency of the inventory system, following the structured process of the SDLC.

Conclusion

Applying the Waterfall SDLC model to the inventory management system demonstrates its suitability for projects with clear, stable requirements. Its structured stages provide clarity and control, ensuring comprehensive documentation and systematic progression. While less flexible for rapidly changing projects, the Waterfall model offers predictability and thoroughness ideal for developing critical business systems, such as inventory management solutions in IT contexts.
