Study Notes
Software Processes
- Software processes are the activities involved in producing a software system.
- Software process models are abstract representations of these activities.
- General process models show how software processes are organized.
- Example models include the waterfall model, incremental development, and reuse-oriented development.
Coping with Change
- Change is inevitable in large software projects.
- Business changes, new technologies, and platform changes all lead to new requirements.
- Changes lead to rework (eg., re-analyzing requirements), and costs to implement new functionality.
- Strategies to handle change include change avoidance (anticipating possible changes) and change tolerance (designing for accommodating changes).
- System prototyping and incremental delivery are two common approaches to handle changing requirements.
Software Prototyping
- Prototypes can be used to test assumptions and show some key features to stakeholders.
- Prototypes help refine requirements earlier in the process.
- Prototyping can reduce the cost of rework in later stages.
- Prototypes can be throw-away (designed for evaluation) or evolutionary (evolving to a final system).
- Prototypes usually do not include non-functional requirements like reliability or security.
- Prototype development involves establishing objectives, defining functionality, building a prototype, evaluating, and reporting on evaluations.
Incremental Delivery
- Incremental delivery develops the system in increments and evaluates each before proceeding to the next.
- Incremental delivery is typically used in agile methods.
- Evaluation is typically done with the user/customer.
- Deploying increments for use by end-users allows for more realistic evaluation.
- Incremental delivery may be challenging for replacement systems where increments will necessarily have less functionality than the existing system.
- Process steps usually include: defining requirements, assigning to increments, designing architecture, developing system increments, validating increments, integrating, validating, deploying, and checking if the final system is complete.
Boehm's Spiral Model
- Boehm's spiral model is a risk-driven software process framework that uses iteration and risk management.
- The process is represented as a spiral.
- Each loop represents a phase in the process.
- The model combines change avoidance with change tolerance to account for risks in the project.
- The model explicitly includes risk management activities.
Rational Unified Process (RUP)
- The Rational Unified Process (RUP) is a modern, generic process model with sequential phases (inception, elaboration, construction, and transition).
- RUP's phases are performed iteratively, enabling incremental development.
- RUP activities (requirements, analysis, and design) are separated from the phases themselves.
