Study Notes
Software Engineering
- Software costs often outweigh other hardware costs associated with computer systems.
- Agile software development processes are iterative and responsive to change.
- The Waterfall model is a plan-driven, linear approach to software development.
- In Incremental models, development phases are interleaved; design, specification, and validation happen simultaneously.
- Software Engineering focuses on practical application, while Computer Science focuses on theory and fundamentals.
- The Waterfall model is not suitable for projects with evolving requirements due to the high cost of change implementation.
- System engineering addresses the overall development of a system where software engineering is one component.
- Generic software specifications are controlled by the software developer.
- Change is a constant in large software projects.
- User requirements are intended for users, while System requirements are meant for developers.
- Agile methods prioritize flexibility and rapid feedback rather than detailed upfront documentation.
- Building complete, consistent, and accurate requirements documents is a complex process.
- Requirements consistency means that the requirements should not contradict each other.
- Non-functional requirements are as crucial as functional requirements, and can influence the overall quality and success of software.
- Objectives are measurable statements, while goals are broader and less concrete in measurement.
- Closed interviews use pre-defined questions for a structured approach, while open interviews allow for flexibility and open-ended discussions
