Use-Case Modeling and User-Centered Development: A Guide to Business Requirements

How is use-case modeling related to user-centered development?

Use-case modeling is fundamentally linked to user-centered development. By documenting the interactions between users and a system, it helps us understand and define how users will interact with the system. This process focuses on capturing functional requirements from a user's perspective, outlining their goals, actions, and behaviors. This information is then used to design user-centered solutions that effectively meet user needs and expectations.

How to find business requirements use cases?

Uncovering business requirements use cases involves a systematic approach:

Gather requirements: Begin by collecting all business requirements for the system. This can be achieved through stakeholder meetings, interviews, surveys, or any other effective information-gathering method.
Analyze requirements: Scrutinize the gathered requirements to identify different user roles and their goals when interacting with the system. Understand the specific actions and behaviors users need to perform to achieve their objectives.
Define use cases: Based on your requirement analysis, define each use case. Each use case should represent a specific user interaction or goal while using the system. Clearly describe the steps involved in each use case and the expected outcomes.
Validate and refine: Share your defined use cases with stakeholders for feedback. This will help you validate the accuracy and completeness of your use cases and refine them as needed.
Document and communicate: Document the finalized business requirements use cases in a clear and understandable format. Communicate these clearly to the development team, designers, and other stakeholders involved in the system development process.

Example: Participants and Business Requirements Use Cases

Let's illustrate this with an example:

**Participants:**1. User: A person who interacts with the system to perform specific tasks.2. Administrator: A person who manages and controls the system.3. Manager: A person who oversees the system's performance and makes strategic decisions.

**Business Requirements Use Cases:**1. Use Case Name: User Registration * Use Case Description: The user wants to create a new account in the system to access its features. * Participants: User

Use Case Name: Data Analysis * Use Case Description: The manager wants to analyze the data collected by the system to make informed decisions. * Participants: Manager
Use Case Name: User Management * Use Case Description: The administrator wants to manage user accounts, including adding, removing, and modifying user details. * Participants: Administrator

Implementation Proposals and Feasibility Analysis

Consider these 2-3 implementation proposals and their feasibility analysis for your custom system:

(1) Candidate System Matrix:

| Features | Candidate System 1 | Candidate System 2 | Candidate System 3 ||---|---|---|---|| Introduction | | | || Input Method | | | || Output Method | | | || Hardware Requirements | | | || Required Software Tools | | | || Required Software Packages | | | || Data Storage Solution | | | || Data Processing Method | | | || Distributed Processing Required | | | || Distributed Processing Architecture | | | |

(2) Feasibility Analysis Matrix:

| Feasibility Criterion | Weight | Candidate System 1 | Candidate System 2 | Candidate System 3 ||---|---|---|---|---|| Operational Feasibility | | | | || Policy Feasibility | | | | || Technical Feasibility | | | | || Schedule Feasibility | | | | || Economic Feasibility | | | | || Legal Feasibility | | | | || Score | | | | |

This structure will help you analyze and choose the most suitable approach for your project.
