What are PERT/CPM charts?

A recognizable event or reference point to track progress.

What is a project milestone?

Project size, human resources, experience, and constraints.

What factors affect task duration?

The longest sequence of dependent tasks; delays here delay the project.

What is the critical path?

The difference between the latest and earliest start times of a task.

What is slack (float) time?

Peer review of a project member’s work during SDLC.

What is a structured walk-through?

Because delays there directly delay the entire project.

What are the steps in risk management?

Features needed in an information system to satisfy business needs.

What are system requirements?

Functional and non-functional.

What are the two types of requirements?

What are common requirement challenges?

Scalability and security.

What additional considerations should be included in requirements?

A method that involves users directly in the development process.

What is Joint Application Development (JAD)?

Better user participation, ownership, accurate requirements.

What are JAD advantages?

Expensive, cumbersome with large groups.

What are JAD disadvantages?

A group-based, prototyping method that reduces cost and time.

What is Rapid Application Development (RAD)?

Incremental system building with continuous user feedback.

What is Agile development?

Agile method with time-boxed sessions and team deliverables.

What is Scrum?

Flexibility, frequent deliverables, reduced risk.

What are Agile advantages?

High skill needed, less documentation.

What are Agile disadvantages?

Interviews, document review, observation, questionnaires, brainstorming, sampling, research.

What are the main requirements gathering techniques?

Select interviewees, set objectives, prepare questions, conduct, document, evaluate.

What are the steps in an interview for requirements gathering?

Asking Who, What, Where, When, How about the system.

What is fact-finding (elicitation)?

Natural language, diagrams (FDD, BPMN, DFD), UML (use case, sequence).

What are requirements representation methods?

Validation: Are the right requirements stated? Verification: Are requirements stated correctly?

What is requirements validation vs. verification?
