Study Notes
Software Development Models
- Incremental Development: Allows for quick delivery of working systems.
- Reuse-Oriented Development: Systems are built from existing components.
- Integration and Configuration: Based on software reuse, systems are built by integrating existing components.
- Commercial-off-the-shelf (COTS): Refers to pre-made software applications that can be purchased and used.
Types of Reusable Software
- Stand-alone application systems (often COTS): Configured for specific environments.
- Object collections packaged for integration: Developed with frameworks like .NET or J2EE.
- Web services: Designed according to service standards, available for remote invocation.
Reuse-Oriented Software Engineering Key Stages
- Requirements Specification: Defines the system needs.
- Software Discovery and Evaluation: Identifies suitable reusable components.
- Requirements Refinement: Adapts requirements to the available components.
- Application System Configuration: Sets up the system based on chosen components.
- Component Adaptation and Integration: Modifies and combines components as needed.
Advantages & Disadvantages of Reuse
- Advantages: Reduced cost and risks of development, faster delivery.
- Disadvantages: Inflexible requirements due to limitations of reused components, loss of control over the evolution of reused system elements.
Software Validation
- Verification and validation (V&V): Ensures the system meets its specifications.
- System testing: Executes the system using real data to confirm functionality.
Stages of Testing
- Component Testing: Independently testing individual components (functions, objects, or groups).
- System Testing: Testing the entire system, focusing on integrated functionality.
- Customer Testing: Using real customer data to ensure the system meets their needs.
Software Evolution
- Software is inherently flexible and changes: Requirements evolve, necessitating software updates.
- The line between development and maintenance is blurring: More systems are built on top of existing software.
Change Impacts
- Change is inevitable in software projects: Due to business needs, technological advancements, and platform updates.
- Change costs include rework and new functionality implementation: Reanalyzing requirements adds to the cost.
Methods to Reduce Rework Costs
- Change anticipation: Planning for potential changes early on to minimize rework.
- Change tolerance: Designing the process to accommodate changes easily and cheaply.
Managing Changing Requirements
- System prototyping: Creating a basic version to test customer requirements and design choices.
- Incremental delivery: Delivering parts of the system for feedback and experimentation.
Benefits of Prototyping
- Improved system usability.
- Better alignment with users' needs.
- Enhanced design quality.
- Easier maintenance.
- Reduced development effort.
Process Improvement Cycle
- Process measurement: Collecting data to establish a baseline for comparison.
- Process analysis: Evaluating the existing process to identify weaknesses and bottlenecks.
- Process change: Implementing changes based on analysis to improve process efficiency.
Process Measurement & Metrics
- Quantitative data is preferred: Measuring attributes of the process or product.
- Metrics should be used to assess improvements: The goal of improvement is to optimize organizational objectives.
- Common metrics: Time taken for activities, resources used, and the number of events (e.g., defects found).
SEI Capability Maturity Model
- Initial: Uncontrolled process.
- Repeatable: Defined procedures for product management are established and followed.
- Defined: Defined procedures and strategies for managing the process itself.
- Managed: Strategically defined quality management strategies are implemented.
- Optimizing: Process improvement strategies are defined and used to continuously refine the process.
Key Points: Software Processes
- Activities involved in creating software: Processes are defined by how these activities are organized.
- General Process Models: Frameworks like waterfall, incremental development, and reuse-oriented development.
- Requirements Engineering: Defines the system's specifications.
- Design & Implementation: Converting requirements into executable software.
- Software validation: Ensuring the system meets its specification and user needs.
- Software Evolution: Adapting software to changing requirements.
- Coping with Change: Prototyping and incremental delivery help manage change.
- Iterative Development: Allows for changes without disrupting the entire system.
- Process Improvement: Agile approaches focus on reducing overhead, while maturity-based approaches emphasize better management and practice.
- SEI Capability Maturity Model: Defines maturity levels based on good software engineering practices.
