Lecture 12

Question 1

What is the ‘Software Process’?

Answer 1

A structured set of activities required to develop a software system.

Question 2

What do software processes generally involve?

Answer 2

• Specification
• Design
• Validation
• Evolution

Question 3

What is the ‘Waterfall’ model?

Answer 3

Sequential (non-iterative) design process.

Question 4

What is incremental development?

Answer 4

The incremental build model is a method of software development where the product is designed, implemented and tested incrementally (a little more is added each time) until the product is finished. It involves both development and maintenance.

Question 5

The V model is similar to what?

Answer 5

Agile software development process

Question 6

What does User Centered Design (UCD) strives for?

Answer 6

• end user is given credence throughout the entire design process, often through direct participation
• requires discipline, empathy and humility
• continual validation of assumptions, refinement of understanding of user context, needs and desires relevant to the system being designed

Question 7

What are some tools available for UCD?

Answer 7

• Meetings
• Focus groups
• Card Sort
• Interview
• Data analysis
• Usability test
• Paper prototyping

Question 8

Why does agile and UCD clash?

Answer 8

“Agile teams are more proficient in executing the development process, but the compressed timescale forces some to abandon user research and degrade the resulting user experience.”

Question 9

How to prevent UCD and agile issues

Answer 9

• Stay “one story ahead” of development
• Use ‘Lean UX’ tools (sketches and mockups)
• Apply ‘discount usability’ techniques

Question 10

The Rational Unified Process (RUP) emphasizes what?

Answer 10

Distinctly phased and iterative development

Question 11

At the core of RUP, what tool is used?

Answer 11

UML for all phases.

Question 12

What are the six engineering disciplines in RUP?

Answer 12

• Business modelling
• Requirements
• Analysis and design
• Implementation
• Test
• Deployment

Question 13

What are the three roles in RUP?

Answer 13

• Configuration and change management
• Project management
• Environment

Question 14

The four phases in RUP are?

Answer 14

1. Inception
2. Elaboration
3. Construction
4. Transition

Question 15

Define the Inception Phase in RUP.

Answer 15

understanding context, preliminary identification of needs, preliminary risk assessment

Question 16

Define the Elaboration Phase in RUP

Answer 16

building more sophisticated, complete understanding of needs. Targeting high risk elements, deriving executable candidate architecture. “Mile wide and inch deep” view of the system.

Question 17

Define the Construction Phase in RUP

Answer 17

developing and testing components, integrating components into codebase. Manufacturing phase vs. creation of intellectual property. High cost, high risk, high inertia.

Question 18

Define the Transisition Phase in RUP

Answer 18

beta testing, refining system details, deploying system

Question 19

What are the six best practices of RUP?

Answer 19

• Iterative development
• Requirements management
• Use of Components
• Use diagraming
• Quality assurance
• Change management
