Requirements Engineering - Lecture Flashcards
What is Requirements Engineering (RE)?
RE is the practice of identifying and analyzing stakeholder needs, documenting these requirements, and managing the scope of the project.
What is the purpose of RE?
RE ensures that the developed system meets user expectations and functions as intended.
Name at least two reasons why RE is essential.
EXAMPLES:
- Prevents costly failures by identifying potential issues early.
- Enhances stakeholder satisfaction by aligning deliverables with expectations.
- Improves project success rates with well-defined, validated requirements.
- Rigorous RE processes are essential in safety-critical applications like aviation, healthcare, and automotive.
What do functional requirements cover?
What the system should do (user login, data storage, retrieval, etc,. . .)
What do non-functional requirements cover?
System attributes and performance criteria (e.g., system must handle 1000 simultaneous users, response time should be under 2 seconds).
What do system requirements cover?
Technical specifications for the system environment (e.g., hardware specifications, software environment).
What do user requirements cover?
User interactions and expectations (e.g., intuitive UI design).
What do business requirements cover?
High-level goals that the system must achieve (e.g., increase market share by 20%, improve customer satisfaction).
What is the goal of feasibility?
To determine whether the project is viable from a technical, operational, legal, schedule, and financial perspective.
Name at least 4 elicitation techniques.
Interviews, workshops, surveys, focus groups, observation, document analysis, prototyping, and automated requirement extraction.
Name three analysis techniques.
Use cases, MoSCoW, and Conflict Resolution.
Name three specification techniques.
Software Requirements Specification, User Stories, Models and Diagrams.
What is the goal of validation?
Ensure requirements are correct, complete, and feasible before development begins.
Name three validation techniques.
Requirements Reviews, Prototypes, Testing.
What are the benefits of Model-Driven Engineering (MDE)?
Enhanced communication through graphical representations.
Better alignment between business goals and technical solutions.
Facilitates early detection of conflicts and inconsistencies.
