These flashcards cover key concepts, practices, and methodologies discussed in the CSIT 317 lecture on Systems Analysis and Design.

What is the main challenge faced by most IT departments regarding project demand?

The demand for projects exceeds their ability to supply them.

Who is responsible for selecting projects that provide the highest possible return on IT investments?

Chief Information Officers (CIOs).

What percentage of IT projects are typically not strategic to the business, according to AMR Research?

2–15% of IT projects.

What is Project Portfolio Management (PPM)?

The process of selecting, prioritizing, and monitoring project results.

What are common reasons for project rejection despite positive feasibility?

Lack of budget, ongoing restructuring, or strategic misalignment.

What are the main phases of the Systems Development Life Cycle (SDLC)?

Planning, Analysis, Design, Implementation.

What is the primary focus of the V-Model in project management?

Testing at every development stage.

What are weaknesses of Waterfall development?

Strict sequential phases, long delivery times, late user involvement, limited flexibility.

What methodologies are part of Rapid Application Development (RAD)?

Focuses on speeding up analysis, design, and implementation phases.

What is the key characteristic of Iterative Development?

The project is divided into sequential versions, each delivering fundamental requirements.

What type of prototyping emphasizes thorough analysis before implementation?

Throwaway prototyping.

What are the characteristics of Agile Development methodologies?

Streamlines SDLC using iterative, programming-centric approaches with short development cycles.

What should be considered when selecting a project methodology?

Project characteristics such as user requirements, technology familiarity, system complexity, reliability needs, time schedules, and visibility.

Which methodology provides early prototypes for feedback?

System prototyping and throwaway prototyping.

What project characteristics favor using the V-Model methodology?

Projects requiring high reliability.
