Study Notes
Systems Design Modeling
- Uses data flow diagrams, entity life histories, and entity relationship diagrams.
Physical Design in Systems Design
- Focuses on system input, verification/authentication, processing, and output.
- Does not refer to the tangible hardware components.
- Example: A personal computer's physical design includes keyboard input, CPU processing, and monitor/printer output, not the physical hardware layout.
System Design Process Steps
- Requirements analysis: Assessing end-user needs.
- Benchmarking: Evaluating current system usage.
- Systems architecture: Creating a blueprint specifying hardware, software, personnel, and data resources; multiple architectures may be evaluated.
- Design: Creating system models; documenting system descriptions without specific brand mentions.
- Computer programming/detailed design: Specifying final system components.
- System testing: Evaluating functionality against expectations, including integration aspects.
System Analyst's Role
- Guides information system development.
- Aligns information system objectives with organizational goals. The role varies across organizations.
Work Breakdown Structure (WBS)
- A task-oriented hierarchy representing project components.
- Tasks may rely on multiple activities and require coordination.
- Contractor support requires a Statement of Work (SOW) outlining SDLC phase tasks.
Iterative and Incremental Development
- Cyclic software development process addressing waterfall model weaknesses.
- Starts with planning, ends with deployment, with cyclic interactions.
- Core to Rational Unified Process, Extreme Programming, and Agile frameworks.
- Increments deliver functional slices through cross-discipline work.
- Phases include inception, elaboration, construction, and transition.
Inception Phase (Iterative/Incremental)
- Identifies project scope, risks, and high-level requirements (functional and non-functional).
Elaboration Phase (Iterative/Incremental)
- Delivers a working architecture mitigating top risks and fulfilling non-functional requirements.
Construction Phase (Iterative/Incremental)
- Incrementally builds the architecture with production-ready code.
Transition Phase (Iterative/Incremental)
- Deploys the system to the production environment.
Extreme Programming (XP)
- Software development methodology improving software quality and responsiveness to changing customer requirements.
- Agile development approach advocating frequent releases in short cycles for increased productivity and adapting to new customer needs.
Business Analysis
- Identifying business needs and determining solutions (system development, process improvement, organizational change, or strategic planning).
- Carried out by business analysts (BAs).
- Overlaps with requirements analysis/engineering, focusing on organizational changes for strategic goal achievement.
Business Analysis Examples
- Enterprise/company analysis: Understanding business needs, strategic direction, and initiatives.
- Requirements planning/management: Planning the requirements process, prioritizing implementation, and managing change.
- Requirements elicitation: Collecting requirements from stakeholders.
- Requirements analysis: Developing and specifying detailed requirements for implementation.
- Requirements communication: Ensuring stakeholder understanding of requirements and implementation.
Joint Application Design (JAD) Sessions
- Participants: Workshop facilitators, business analysts, system analysts, process analysts, project leaders, development team members, business managers, and IT members.
- More expensive and cumbersome than traditional methods but fosters user ownership and support. Potential for interpersonal conflict. Most effective in small, focused projects.
- Improves accuracy of requirements, understanding of common goals, and commitment to project success.
- Part of the Dynamic Systems Development Method (DSDM) prototyping lifecycle.
- Workshop where knowledge workers and IT specialists define and review business requirements.
- Helps resolve difficulties between knowledge workers and IT specialists regarding the new system.
Four Key Steps in JAD Sessions
- Define session objectives: Clarify the purpose, desired outcomes, and participant roles.
- Prepare for the session: Conduct pre-session research, create an agenda, arrange logistics, and prepare participants.
- Conduct the JAD session: Facilitate the session, manage the agenda, ensure consensus, and keep the meeting on track.
- Produce documents: Record information from discussions, review with participants, and finalize documents promptly after the session.
