Study Notes
Software Processes
- Software processes are a series of technical, collaborative and managerial activities with the goal of building and testing a software system
- There are four main process activities for software systems: specification, development (design & implementation), validation (testing), and evolution.
- The order of these activities can vary depending on the type of software development process being used. For example, the waterfall model uses a sequential approach, while incremental development interleaves these activities.
Software Specification
- The process of outlining the services required and the limitations of the system
- Requirements Engineering is the process of determining these needs and limitations
- Requirements engineering includes elicitation and analysis
Stakeholders
-
Stakeholders are people (or groups) who are impacted by a system and can include:
- Users: People who directly use the system
- Managers: Individuals who oversee the use of the system
- Customers: Those who purchase the system
- Developers: Those who build and maintain the system
- External stakeholders: Entities that can influence the system, such as government agencies or communities
Software Development (Design and Implementation)
- This is the process of translating the system specification into an executable application
- This involves two main phases:
- Software Design: Defining the structure, components, and relationships within the system
- Implementation: Translating this designed structure into actual code
Design Activities
- Architectural design: Determining the high-level structure of the system, including its main components and how they are distributed
- Database design: Designing the data structures and how they are represented in a database
- Interface design: Defining the communication interfaces between components within the system
- Component selection and design: Identifying reusable components or designing new ones to meet specific needs
Software Validation (Testing)
- Verification & Validation (V&V) involves checking that the system complies with its specification and fulfills the customer's requirements
- This includes reviewing the system documentation and implementing system testing
- System testing involves using test cases derived from the real data that the system will work with
Stages of Testing
- Component testing: Individually testing each component of the system (e.g., functions or objects), focusing on individual functionalities.
- System testing: Testing the system as a whole, including testing how different components work together. This includes testing emergent properties, which are properties that only exist when components interact.
- Customer testing: Involving the customer in testing the system with their own data to ensure it meets their specific needs.
Software Evolution
- Software is inherently flexible and changes throughout its life cycle.
- As business needs evolve, so must the software that supports them.
- The lines between software development and an ongoing evolution (maintenance) are becoming increasingly blurred.
Recap
- The four basic process activities in software development:
- Specification
- Development (Design and Implementation)
- Validation (Testing)
- Evolution
