Lecture4: Software Development Approaches Quiz

What was the main issue with early ad-hoc development approaches?

• Excessive user participation

• Lack of structure, leading to inconsistent results

• Overemphasis on documentation

• Rigid planning

The Waterfall model is BEST described as:

• Iterative and flexible

• Linear and predictive

• Adaptive to changing requirements

• Focused on prototyping

A key disadvantage of the Waterfall model is:

• High user satisfaction

• Inflexibility to requirement changes

• Excessive collaboration

• Lack of documentation

Structured methods aimed to improve development by:

• Eliminating user involvement

• Breaking processes into smaller, manageable chunks

• Avoiding data analysis

• Using only prototyping

SSADM (Structured Systems Analysis and Design Method) focuses on:

• Only functionality

• Functionality, data, and events

• Ignoring stakeholder input

• Agile principles

A criticism of SSADM is that it is:

• Too flexible

• Too prescriptive, limiting developer creativity

• Lacks focus on data

• Excludes testing

ETHICS emphasizes the importance of:

• Ignoring organizational culture

• Combining technical and human factors

• Using only predictive approaches

• Eliminating user feedback

The Soft Systems Method prioritizes:

• Strictly technical solutions

• Understanding unstructured human interactions

• Frozen requirements

• Avoiding stakeholder input

The Spiral Model is known for:

• Linear execution

• Iterative cycles with risk analysis

• Avoiding prototyping

• No user involvement

Prototyping helps to:

• Delay user feedback

• Reduce uncertainty through early testing

• Increase documentation backlogs

• Eliminate iterations
