Modeling Tools and Techniques Quiz

Feasibility Study

• A feasibility study determines if a requested system is economically and operationally viable for an organization.
• Essential to assess before project initiation to ensure alignment with organizational goals.

Types of Feasibility Tests

• Operational Feasibility: Evaluates the impact and practicality of the proposed system in operational contexts.

Systems Development Life Cycle (SDLC)

• A structured, step-by-step approach for developing information systems.
• Involves determining budgets, gathering requirements, and writing user documentation.

SDLC Phases

• Planning: Define the system, set project scope, and develop a project plan.
• Analysis: Collaborate to gather, understand, and document business requirements.
• Design: Create a technical blueprint and design system models.
• Development: Transform design documents into a functioning system.
• Testing: Verify system functionality against requirements, including unit, system, integration, and user acceptance testing (UAT).
• Implementation: Distribute the system, create documentation, and provide training.
• Maintenance: Monitor and support the system to meet evolving business goals.

Planning Phase

• Define the system to be developed, focusing on critical success factors.
• Set project scope to outline high-level requirements and prevent scope creep.
• Develop a project plan detailing tasks, resources, and timelines, led by a project manager.

Analysis Phase

• Gather detailed business requirements through collaboration, often using Joint Application Development (JAD) meetings.
• Prioritize requirements in a formal Requirements Definition Document.

Design Phase

• Define technical architecture, detailing required hardware, software, and telecommunications.
• Create system models, including graphical representations such as GUIs.

Development Phase

• Build technical architecture and develop databases and programs, primarily executed by IT specialists.

Testing Phase

• Write detailed test conditions outlining expected system performance.
• Conduct various tests: unit testing, system testing, integration testing, and user acceptance testing (UAT).

Implementation Phase

• Document how to use the system and provide training through online or workshop methods.
• Choose an implementation method: parallel, plunge, pilot, or phased.

Maintenance Phase

• Establish a help desk for user support and provide an environment for ongoing system changes.

Modeling Tools and Techniques

• Utilize graphical and non-technical methods to represent systems at various development stages.

Key Modeling Techniques

• Functional Decomposition Diagrams (FDD): Illustrate business functions and their lower-level processes.
• Business Process Modeling (BPM): Use BPMN for visualizing business processes with elements like pools and swim lanes.
• Data Flow Diagrams (DFD): Depict how data is stored, processed, and transformed within the system.
• Unified Modeling Language (UML): Common visual method for documenting software design, including use case and sequence diagrams.

System Requirements Checklist

• Outputs: Specify regular reporting functionalities and inventory updates.
• Inputs: Detail user interactions with data collection terminals and entry requirements.
• Processes: Include essential calculations, such as GPA and payroll updates.
• Performance: Ensure user capacity and response time standards are met.
• Controls: Implement security measures for sensitive operations and record management.

Project Management

• Facilitates organization, tracking, and execution of tasks within a project framework.

This quiz focuses on modeling tools and techniques, particularly functional decomposition diagrams. Participants will explore graphical methods and the role of non-technical language in system development. Assess your understanding of business functions and their organization into lower-level processes.
