Q

what is the SDLC

A

the system development life cycle

the entire process, all activities that are part of sys analysis, design, programming, testing, implementing, and maintaining the sys

AKA: all activities to build, launch, and maintain an information system

Q

characteristics of the predictive approach of the SDLC

A

assumes project can be planned in advance and info sys can be developed according to the plan

requirements are well understood

Q

characteristics of the adaptive approach of the SDLC

A

iterative model

assumes project is more flexible and must adapt to changing needs as project progresses

requirements and needs are uncertain

Q

how are phases completed in waterfall

A

sequentially with no overlap or iteration

once one phase is complete, fall over waterfall and dont go back

Q

cons of the waterfall method

A

design must be completely specificed prior to programming

length deliverables

possible changes in business enviorment between requirements and implementations

Q

what is the difference with modified waterfall

A

assume predictive planning and sequential phases, but recognizes that projects phases must overlap..influencing and depending on one another

Q

what do iterations allow you to do

A

iterations can be used to create a series of mini projects that address smaller parts of application

19
Q

what are some key benefits of iterations

A

project can adapt to any changes as it proceeds

parts of the system are available early on for user evaluation and feedback which helps ensure that the application can meet the needs of the users

most diff problems identified and addressed early in project

20
Q

what is a walking skeleton

A

a complete front to back implementation of the new sys but with only the bare bones of the functionality

21
Q

is agile a complete methodology

A

no

22
Q

which 3 methodologies incorperate agil principals

A

UP

XP

scrum

23
Q

What are the 4 phases of UP SDLC

A
24
Q

in UP, what is a discipline

A

a set of functionality related development activities

25
Q

In the rational unified process RUP what are the dynamic aspects of the process

A

cycles, phases, iterations, and miletones

time

26
Q

In the rational unified process RUP what are the static aspects of the process

A

activities, artifacts, workers, and workflows

static

27
Q

what is the inception phase

A

establish the business case for the system and delimit the proj scope

28
Q

what phase is the actors of the system identified

A

Inception phase

29
Q

which phase are these the outcomes of

A

inception phase

30
Q

What is the purpose of the elaboration phase

A

to analyze the problem domain, establish a sound architectural foundation, develop project plan, and eliminate highest risk elements of the project

develop “mile wide and inches deep” view of the system

31
Q

what is the most critical of the four phases

A

Elaboration phase:

must decide whether or not to commit to the construction and transition phase

32
Q

what is the phase that these are the outcomes of

A

elaboration phase

33
Q

Goal of the construction phase

A

All remaining components and application features are developed and integrated into the product with all features thouroughly tested

34
Q

what is the main transition with the outcomes of the elaboration phase and the construction phase

A

transition from development of intellectual property to development of deployable products

35
Q

what phase are these the outcomes for

A

construction phase

36
Q

What is each phase in RUP further broken down into

A

an iteration

37
Q

defintion of an iteration in the RUP

A

complete developmetn loop resulting in a relase of a:

executable prodct which is a subset of the final prodct and grows incrementally from iteration to iteration

38
Q

what are benefits of the iterations in RUP

A

Risks mitigated earlier

change more manageable

higher level of reuse

project team can learn along the way

better overall quality

39
Q

what is the goal of the transition phase

A

to transition the software product to the user community

40
Q

what are these the outcomes for

A

transition phase

41
Q

What are the 4 values of XP

A

communication

simplicity

feedback

and courage

42
Q

XP has a 3 level approach in a circle with rings format

what are these 3 rings and what do they consist of

A
43
Q

very basic defintion of scrum

A

intense effort involving entire team for definied peroid of time

44
Q

3 things you are asked in daily scrum meeting

A
45
Q

what SDLC are we using for our project
