life cycle
waterfall:
Linear;
each stage gets done;
before going on to the next stage the previous stage has to be finished ;
Reports are produced at the end of each stage.
-
-
spiral:
fewer stages;
heavy client involvement ;
highly adaptive to change;
Evaluation informs design iterations.
advantages
-
can learn from experience, so how many staff is needed or how long the project will take.
prototyping, able to change things
disadvantage
difficult for large projects, it's difficult for everyone to follow
-
requirements are incomplete at the beginning of the project, which could lead to problems later on
RAD:
similar to spiral but requirements are defineded, however the stages are small and are rapidly repeated.

Agile programming:
Not a specific life cycle, because it’s collaboration and people more then process and tools.
people create a solution to a problem
