Unified Process

Question 1

What is iterative development

Answer 1

series of short mini projects - iterations

each iteration gives a tested, integrated and executable system

Question 2

Steps in iteration development

Answer 2

requirements
analysis
design
implementations
integration and system test

Question 3

What is the output of an iteration

Answer 3

not experimental prototype but a production subset of the final system
each iteration tackles new requirements and extends the system

Question 4

key ideas of central unified process ideas?

Answer 4

iterative development is number one
tackle high risk items early
continuous engagement of uses
core architecture in early iterations
test
apply use cases continuously
model with UML
carefully manage requirements
control changes

Question 5

name and explain the unified process phases

Answer 5

Inception - define project scope
elaboration - plan, specify features, baseline architecture
construction - build it
Transition - transfer to user community

Question 6

what are artefacts

Answer 6

docs, diagrams, code that track progress
everything is optional
best kept electronically on website

Question 7

which artefacts can be started/created at inception phase

Answer 7

use case model
vision
supp specification
glossary
SW dev plan
development case

Question 8

waterfall vs agile

Answer 8

waterfall - well documented, traceability, change control, few risks, sequential, late integration and testing
Iterative - little documentation, light process, risk driven, continuous integration and testing

Question 9

prototyping framework

Answer 9

build system to clarify requirements

Question 10

Rapid application development framework

Answer 10

well defined 60-90 day projects

Question 11

incremental framework

Answer 11

deliver increasing functionality at each iteration

Question 12

spiral (boehm) framework

Answer 12

similar set of tasks applied for each turn of the spiral

Question 13

component based framework

Answer 13

aimed at producing and reusing OO components

Question 14

Agile framework

Answer 14

embrace change and adapt to it and keep things simple

Question 15

Process model

Answer 15

framework of tasks applied during software engineering

Question 16

How do iterative methods attempt to reduce risk

Answer 16

bringing out versions early

Question 17

Benefits of iterative development

Answer 17

early reduction of risk
early visible progress
early feedback
managed complexity
get robust architecture
handle evolving requirements
allow for changes
learn and apply lessons withing dev process

Question 18

What does prototyping help to investigate

Answer 18

technical issues
work flow and task design
screen layouts, UI, information display
difficult, controversial, critical areas
match between engineering and customer specification

Question 19

benefits of prototyping

Answer 19

helps to investigate different things within the project
demonstrate proof of concept
more concrete than a narrative

Question 20

Why should we prototype

Answer 20

enable evaluation and feedback
improves communication between a team
testing ideas out - encourages reflection
answer questions
explore alternatives

Question 21

Horizontal prototype

Answer 21

wide range of functions, little detail

e.g. test UI before backend is developed

Question 22

vertical prototype

Answer 22

provide a lot of detail for a few features/functions

Question 23

Throw away prototypes

Answer 23

address high risk issues - uncertainty in requirements, UI design, alternative implementation strategies, tech platform
Only enough effort to help address specific issues
great for trying alternative ideas

Question 24

Evolutionary prototypes

Answer 24

early version of the actual software
will evolve into the final product
quality is important
can be put to limited use
implementing and validating well understood requirements

Question 25

How to make sure that the system works on demo day

Answer 25

no last minute code changes
demo a stable version
rehearse entire demo
resist temptation to change the demo
test any peripherals that are needed

Question 26

how to prepare for a demo

Answer 26

list and test tasks that will be demoed
plan what to say
plan what to say during each test
ensure that each team member participates
rehearse and time the demo
think of questions and prep answers for them
