Study Notes
Systems Analysis vs. Systems Design
- Systems analysis decomposes a system into its components to study interactions and effectiveness.
- Systems design reassembles components into an improved system, allowing modifications and improvements.
- A repository stores documentation related to systems, including project correspondence, reports, and data.
Model-Driven Analysis Methods
- Model-driven analysis emphasizes visual models to document and validate systems.
- Structured analysis focuses on process-centered techniques for analyzing and defining systems.
- Information engineering (IE) synchronizes data and processes through visual representation.
- Object-oriented analysis (OOA) combines data and process concerns, illustrating objects' structure and behavior.
Requirements Discovery Methods
- Requirements discovery involves identifying system problems and solutions through various techniques.
- Fact-finding methods include analyzing existing documentation, observing systems, and conducting interviews.
- Joint requirements planning (JRP) brings together stakeholders for collaborative systems analysis.
- Business process redesign (BPR) applies systems analysis to improve fundamental business processes.
Accelerated Systems Analysis
- Accelerated systems analysis uses prototypes to identify user requirements quickly.
- Discovery prototyping allows users to respond to preliminary system designs.
- Rapid architected analysis derives models from existing systems and prototypes.
Agile Methods
- Agile methods integrate various systems analysis approaches without imposing a single structure.
- Developers can choose tools and techniques based on project needs, enhancing flexibility in development.
Phases of Systems Analysis
- Scope Definition Phase determines project worth and feasibility of developing a new system.
- Problem Analysis Phase assesses issues and drives toward understanding root causes.
- Requirements Analysis Phase captures user needs and desired functionalities.
- Logical Design Phase defines what the system must accomplish.
- Decision Analysis Phase evaluates the best solution to meet system objectives.
Objectives and Constraints
- Objectives measure success, such as reducing uncollectible accounts or increasing application processing.
- Constraints limit flexibility in defining solutions, like budget or operational deadlines.
- A steering body prioritizes project proposals for optimal organizational value.
Functional vs. Nonfunctional Requirements
- Functional requirements describe specific activities and services the system must deliver.
- Nonfunctional requirements include system features like performance, security, and usability.
Expressing System Requirements
- System improvement objectives can be listed or defined through use cases.
- Use cases outline business scenarios representing required system responses.
Prioritization of Requirements
- Prioritization can be facilitated through techniques like timeboxing to manage system development efficiently.
