Chapter 2: Software Processes
- A software process is a set of related activities leading to a software product.
- All software processes must include:
- Software specification
- Software design and implementation
- Software validation (testing)
- Software evolution (maintenance)
- Process descriptions may also include:
- Order of activities
- Products (outcomes of process activities)
- Roles (responsibilities)
- Pre- and post-conditions
Software Process Categories
- Plan-driven processes: Plan all activities in advance, measure progress against the plan.
- Agile Processes: Incremental planning, easier to adapt to changing requirements.
- Finding a balance between plan-driven and agile approaches is crucial for practical software development.
Software Process Models
- Waterfall Model: Sequential phases (requirements, design, implementation, testing, operation & maintenance). Plan-driven.
- Incremental Development: Interleaved specification, development, and validation. Can be plan-driven or agile.
-
Reuse-Oriented Software Engineering: Assemble systems from existing components (COTS).
- Benefits: Reduced development time and cost, reduced risks.
- Disadvantages: Loss of control, potential requirement compromises.
Waterfall Model: Advantages & Disadvantages
- Advantages: Simple, easy to understand and implement, clear phases, easy management.
- Disadvantages: High cost of documents, no working software until late stages, inflexible to changes, high risk.
When to Use the Waterfall Model
- Use in large systems requiring coordination across multiple sites.
- When requirements are well-understood and unlikely to change.
- When delivery time is not a critical factor.
Incremental Development Model
- Develop, validate, and deliver in increments with each adding functionality.
- Focuses on getting initial system and user feedback.
Incremental Development Model: Benefits
- Reduced cost of accommodating change.
- Faster delivery.
- Easier to get customer feedback.
Incremental Development Model: Problems
- Process not visible or easy to manage.
- Difficult for cost-effective or reliable document generation across versions.
- Structure of system may degrade over time with increments.
Coping with Change
- Change is inevitable in large software projects (e.g., changes in business requirements, technologies, platforms).
- Change leads to rework; costs include analyzing requirements for rework and implementing new functionality.
Approaches to Reduce the Costs of Rework
- Change avoidance: Predict changes during development to prevent larger scale rework.
- Change tolerance: Design process to accommodate changes affordably (e.g., using an iterative or incremental approach).
Coping with Changing Requirements
- Methods for accommodating changes during development.
- System Prototyping: Quick development of system versions to test and clarify requirements.
- Incremental delivery: Successive delivery of system increments to evaluate feedback and incorporate changes.
Software Prototyping
- Initial version of system for validation and demonstrating concepts.
- Used for exploring design options and gathering requirements, validating design decisions.
The Process of Prototype Development
- Establishing prototype objectives.
- Defining prototype functionality.
- Outlining prototype definition.
- Developing an executable prototype.
- Evaluating the prototype (through evaluation reports).
Prototype Development Considerations
- Prototypes may omit certain functionality for faster turn-around.
- Prototypes focus on functional rather than non-functional requirements (reliability, security).
Throw-Away Prototypes
- Should be discarded after development since they're not viable for production use.
- Difficult to meet quality and flexibility standards.
- Difficult to adapt to changing non-functional requirements
Incremental Delivery
- Successive system deliveries in increments.
- Prioritize user requirements, prioritizing and adding early on.
- Integrate each increment into an evolving system gradually improving functionality.
Incremental Development & Delivery
- Develop increments, evaluate incrementality before moving onto next increment.
- End-users can use increments.
- Difficult to implement for replacing systems if functionality of existing system surpasses incrementality.
Incremental Delivery Advantages
- Early value delivery to clients.
- Early user feedback and requirements clarification.
- Reduced risks for complex projects.
Incremental Delivery Problems
- Requirement understanding may be incomplete for all components.
- Difficulty in defining a complete contract.
- Difficulty in identifying common facilities used across multiple increments.
