Systems Design
Systems Design
The process of defining, organizing, and structuring the components of a solution to serve as a blueprint for implementation.
Analysis -> Design -> Implementation
Analysis -> Design -> Implementation
The sequential phases of creating a new system. Analysis provides the groundwork for design, and design paves the way for implementation.

Study Notes
Systems Design Overview
- Systems design is the starting point for implementation
- Design analysis results are documented
- Design components form the final solution for construction
Analysis to Design to Implementation
- Analysis objective: understand and specify the new system's purpose
- Design objective: detail how the new system will be implemented
- Implementation objective: create a system that meets user needs
Bridging from Analysis to Implementation
- Object-Oriented (OO) Design: detailed OO design models are created for use
- OO advantages: requirement models are extended to design models, avoids reinventing the wheel
- Design models are created to support actual coding
- Agile approach: create models only if needed; simple details can be coded without a design model
Analysis Models to Design Models
- Flowchart showing different models, including requirements models, domain, deployment, class, use case, activity, interaction, system sequence diagrams, and design state machine diagrams related to the system
- Each model fulfills a specific purpose in connecting analysis to design and eventual implementation
Design Activities
- Design activities match the new system's components
- Design activities & Iterations: identify problem and obtain approval, plan and monitor project, discover details, design system components, build, test, and integrate components, complete system tests and deploy solution
Key Design Questions for Each Activity
- System interaction: how the system interacts with other systems and existing technologies
- Information system components and interactions
- User interaction: user interface
- Data handling: capture, structure, and store data
- Component structure: ensures efficient construction and deployment
Design Models
- Project complexity and depth determine model type
- Agile/iteration projects often build models "on the fly", but still use models
- Jumping to programming without design can lead to sub-optimal solutions, rework may be required
Analysis to Design to Implementation Model Flow
- Flowchart linking analysis models (information about things, problem domain class diagram, use case descriptions, system sequence diagrams, activity diagrams) to design models (design class diagram, communication diagrams, sequence diagrams, CRC cards) and programming models (object-oriented program classes with methods)
