Rational Unified Process (RUP)

 UP

is generally used to describe the generic process, including those elements which are common to most refinements
 UP is also used to avoid potential issues of copyright infringement since Rational

Waterfall Approaches

Unified Process
Waterfall Approaches

Unified Process

Prescriptive
• Insist on all steps being followed exactly

Adaptive
• Allows for change within certain guidelines

Sequential
• Completes each phase one after another and only once.

Iterative
• Completes the entire information system in successive iterations.

Leaves testing to the end of project lifecycle

Early iterations focus on requirements, later iterations on implementation and testing 4

Main Points


If you want to have a Spectacular Failure with the
RUP, there are seven steps that you can follow.

Step 1: Superimpose “Waterfall” thinking
Step 2: Apply the RUP as a Heavy, Predictive
Process
Step 3: Avoid Object Technology Skills
Step 4: Undervalue Adaptive Iterative
Development
Step 5: Avoid Mentors Who Understand Iterative
Development
Step 6: Adopt the RUP in a Big Bang
Step 7: Take Advice from Misinformed Sources

Step 1: Superimpose “Waterfall”
Thinking (1)
 What


is “Waterfall” Thinking?

Follows a fixed order and only start next phase when current phase is completed

 Waterfall

approach drew inspiration from what was known and familiar, such as engineering and construction in other domains, such as building


Do the Requirements, then do the Design, then Construct
