(2) design your product eg. make diagrams with UML
(3) realize the product
(4) vefify and test your product and fix errors
(5) deliver your product
(6) maintenance your product at customer site
There is a modification which allows you to step from one action back to the previous one if you detect some mistakes.
This process is very static and you have to focus mainly on acquiring the requirements because its difficult and expensive to do the whole process again if your customer istn’t satisfied.
