Study Notes
Ethnography and Requirements Analysis
- Ethnographic methods examine current practices, which may be historically based and potentially irrelevant today.
- Approaches combine ethnographic analysis, focused ethnography, debriefing meetings, and prototype evaluation to enhance requirements analysis.
Stories and Scenarios
- Use scenarios and user stories to illustrate real-world system applications, grounded in practical situations stakeholders can relate to.
- These narratives facilitate stakeholder engagement, driving discussion on their experiences related to system usage.
Case Study: Photo Sharing in the Classroom
- Primary school teacher Jack utilizes an iLearn wiki for a project on the fishing industry, encouraging pupils to gather and share related historical materials.
- Jack seeks a photo-sharing platform, ultimately using KidsTakePics, which allows moderation by teachers, highlighting the significance of stakeholder feedback in system selection.
Interviewing Techniques
- Both formal and informal interviews with stakeholders are integral to requirements engineering (RE).
- Closed interviews follow a predetermined question set, while open interviews explore broader issues, emphasizing an open-minded approach to gather insights.
Challenges in Interviews
- Communication barriers can arise; application specialists might use jargon that confuses requirements engineers.
- Effective interviews depend on prompting discussion rather than simply soliciting direct requests for system features.
Use Cases
- Use cases, a scenario type within UML, identify system actors and interactions, serving as a comprehensive model of system usage.
- Use cases consist of high-level graphical models supported by detailed tabular descriptions, often enhanced by UML sequence diagrams.
Software Requirements Document
- The software requirements document outlines user and system requirements, distinct from design documents, centering on what the system should accomplish.
- It is essential to define requirements clearly to avoid ambiguity during system development.
Requirements Validation
- Validation ensures requirements align with customer expectations, preventing costly fixes after delivery, which can far exceed initial validation costs.
- Key aspects of requirements validation include checking validity, consistency, completeness, realism, and verifiability.
Requirements Validation Techniques
- Incorporate regular requirements reviews, systematic manual analysis, prototypes, and test-case generation to verify requirements effectively.
- Involve both client and contractor personnel in reviews to foster communication and resolve potential issues early.
Review Checks
- Assess requirements for verifiability, comprehensibility, traceability, and adaptability to ensure their robustness and flexibility throughout the development process.
Changing Requirements
- Post-implementation, business and technical landscapes evolve, often leading to new user needs or system interface requirements driven by organizational changes.
- Addressing these changes is crucial for maintaining system relevance and utility in a dynamic environment.
