Study Notes
Definition of a Process Model
- A process model is a structured approach to software development that outlines tasks, activities, and roles.
- It defines the sequence of steps from project initiation to delivery.
- Process model benefits include:
- Planning: Defines project timeline and resource allocation.
- Communication: Facilitates shared understanding among stakeholders.
- Quality Assurance: Ensures each phase meets standards before moving to the next.
- Risk Management: Identifies potential risks early.
- Components of a process model:
- Phases: Distinct stages of development, such as requirement analysis, design, implementation, testing, and deployment.
- Activities: Specific tasks within each phase.
- Milestones: Key points indicating completion of a phase or important task.
Waterfall Model
- Linear and sequential approach where each phase must be completed before proceeding to the next.
- Phases include:
- Requirements Analysis: Defining software functionalities.
- System Design: Outlining system architecture and design.
- Implementation: Writing the code.
- Testing: Identifying and resolving defects.
- Deployment: Releasing software to users.
- Maintenance: Ongoing support and updates.
- Popular for projects with well-defined requirements and minimal expected changes.
Waterfall Model Advantages
- Easy to understand and follow.
- Well-structured with clear milestones.
- Suitable for projects with predictable requirements.
Waterfall Model Disadvantages
- Inflexible to changes once development starts.
- Late discovery of issues as testing occurs after implementation.
- Not ideal for complex projects with evolving requirements.
V-Model
- An extension of the Waterfall model emphasizing verification and validation.
- Integrates testing phases alongside development phases for early defect detection.
- Verification focuses on ensuring the product meets defined requirements.
- Validation ensures the product meets user needs.
- Popular for projects where quality and reliability are critical.
