Software process model Flashcards

1
Q

is an imperfect replica of something real, but the model has several advantages over the original:

is less expensive
it can be built more quickly
it is easier to change
it is easier to handle

Q

a simplified description of a software process that presents one view of that process. Process models may include activities that are part of the software process, software products and the roles of people involved in software engineering:

Q

This represents the process as a set of activities, each of which carries out some data transformation. It shows how the input to the process, such as a specification, is transformed to an output, such as a design. The activities here may represent transformations carried out by people or by computers.

Q

Only when one phase is finished does the project team drop down (fall) to the next phase
Fairly rigid approach
Can’t easily go back to previous phases (each phase would get “signed off”)

9
Q

many activities are done now in an overlapping or concurrent manner
Done for efficiency – when activities are not dependent on the outcome of others they can also be carried out (but dependency limits overlap)
- Waterfall is not realistic

Q

Why would corporate manager types like the waterfall life cycle model?

A

Minimizes change, maximizes predictability
Costs and risks are more predictable
Each stage has milestones and deliverables: project managers can use to gauge how close project is to completion
Sets up division of labor

22
Q
  • combination of incremental and iterative
  • the ability to adapt to the change in requirements.
  • client is also involved in the development process
  • iterative and incremental, it follows a cyclical approach improving
    the product incrementally with every loop.
A

Adaptive

23
Q
  • developed piece-by-piece until it is fully completed.
  • based on predictions and planning,
  • The project scope, timeline, and software development cost are determined at the initial phase
A
