SE3 UML

Question 1

What is the software development life cycle

Answer 1

process of building or maintaining software systems

Question 2

Give 3 examples of a traditional software methodology

Answer 2

V-Model
RUP
Waterfall
Spiral

Question 3

What are the typical phases of a traditional software process

Answer 3

Requirements, Analysis, Design, Implementation, Testing, Maintenance (Waterfall)

Question 4

Define the characteristics of a traditional software process

Answer 4

sequential, on-going documentation, predetermined processes, know all requirements beforehand

Question 5

Identify an agile development process and briefly explain its purpose

Answer 5

an agile development process such as the Unified Software Development Process(USDP) is based on the idea of incremental and iterative development

the phases of the development life cycle are revisited repeatedly and adjusted accordingly

Question 6

Identify the characteristics of an agile development process

Answer 6

iterative and incremental
early customer involvement
iterative development
self organising teams
adapts to change

Question 7

Name 6 agile development methods

Answer 7

Crystal methodologies
DSDM
Feature driven development
lean software development
scrum
XP

Question 8

Features of agile methodologies

Answer 8

emphasis on teams
working software
customer collaboration
responding to change

Question 9

Features of traditional methodologies

Answer 9

focus on documentation(contracts)

plans, process and tools

Question 10

What are the phases in an agile methodology

Answer 10

Inception, Elaboration, Construction, Transition

Question 11

What are some of the problems with the traditional life cycle

Answer 11

developments are rarely sequential
users often do not know what they want
errors in design may not be obvious until very late in the project
is not the best model for modern development tools
addresses technical rather than user needs

Question 12

What is the USDP

Answer 12

Developed by the team that created UML
Embodies best practice in system development
Adopts an iterative approach with four main phases
Different tasks are captured in a series of workflows

Question 13

What are the characteristics of USDP

Answer 13

Iterative and incremental development
Component-based development
Requirements-driven development
Configurability
Architecture-centrism
Visual modelling techniques

Question 14

What are the 4 phases of USDP

Answer 14

Inception
Elaboration
Construction
Transition

Question 15

Describe the USDP process

Answer 15

Composed of Phases, workflows and Iterations
Phases - Inception, Elaboration, construction, Transition
Workflows - Requirements, Analysis, Design, Implementation, Test

Within each phase activities are grouped into workflows
The balance of effort spent in each workflow varies from phase to phase
Within phases there may be more than one iteration

Question 16

What are some characteristics of the Waterfall Life Cycle

Answer 16

In a waterfall life cycle project the phases and the workflows are linked together
In the Requirements phase, only Requirements workflow activities are carried out
All Requirements activity should be completed before work starts on Analysis
In an iterative life cycle project it is recognised that some Requirements work will be happening alongside Analysis work

Question 17

What is the Agile Manifesto

Answer 17

Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan

Question 18

Name some approaches to software development

Answer 18

Structured methods (SSADM, etc.)
Computer-aided software engineering (CASE)
End-user development (inc. 4GLs)
Application software packages & outsourcing
Prototyping
Rapid Application Development (RAD)
Dynamic or Agile methods (DSDM, etc.) 
Web services
Object-oriented development
