Q

what are the disadvantages of waterfall model?

A
  • no user preview
  • reqs must be known
  • future deliverables are frozen
  • false sense of progress
  • integration happens at the end
  • linear instead of iterative

Q

when to use waterfall model?

A
  • clear reqs
  • clear technology
  • clear product definition
  • creating new system for existing product
  • porting an existing system to new platform
18
Q

which process model is characterized by rigidity?

A

waterfall

19
Q

which process model is characterized by “quick & dirty” methods.

A

structured evolutionary prototyping model

20
Q

what is prototyping?

A

building a software product that displays the functionality of the product but not the actual logic

21
Q

what are the steps in SEPM?

A
  • develop project plan
  • create partial model
  • specify reqs for partial model
  • develop prototype
  • demonstrate prototype
  • repeat
22
Q

what are advantages of SEPM?

A
  • clear signs of progress
  • user feedback
  • accurate end product
23
Q

what are disadvantages of SEPM?

A
  • “code & fix”
  • “quick & dirty”
  • maintainability is overlooked
  • user may want prototype delivered
  • loop may be never ending
24
Q

when to use SEPM?

A
  • unclear reqs
  • new dev’t
  • UI dev’t
  • OO dev’t
  • short demonstrations
25
Q

which model provides high quality with reduced time?

A

RAD model

26
Q

_________ uses minimal planning in favor of rapid prototyping?

A

RAD model

27
Q

what are the phases of RAD model?

A

R U Coming to Class
- req planning
- user description
- construction
- cutover

28
Q

what is used to manage risk of cost & schedule in RAD model?

A

time-box approach

29
Q

what are the advantages of RAD?

A
  • lower cost
  • time box
  • user feedback
  • from documentation to code
30
Q

what are disadvantages of RAD?

A
  • quick response to users
  • commitment to rapid activities
  • requires modularization
  • unachieved closure
  • hard to use with legacy systems
31
Q

when to use RAD?

A
  • reasonably known reqs
  • system modularization
  • time box
  • user involvement
  • low technical skill
  • low performance
  • incremental progress
32
Q

what 2 things does spiral SDLC model combine?

A

risk analysis of RAD & linear sequential flow of waterfall

33
Q

at which stage of the spiral model are all proposed alternatives analyzed for risk?

A

identify & resolve risk

34
Q

at what stage of the spiral model are prototypes built?

A

identify & resolve risk

35
Q

at what stage of the spiral model are features like designing and code reviews implemented?

A

develop next version

36
Q

at what stage of the spiral model does customer evaluation take place?

A

plan next phase

37
Q

what are the phases of the spiral model?

A
  1. define obj, constraints & alt
  2. identify & resolve risks
  3. develop next version
  4. plan next phase
38
Q

what are advantages of spiral model?

A
  • early risk indications
  • frequent cost assessment
  • early dev’t of risky features
  • design doesn’t need to be perfect
  • user feedback
39
Q

what are disadvantages of spiral model?

A
  • unclear milestones
  • requires risk analyst
  • complex model
