Given the right circumstances, even good people can go astray as our psychology push us down the slippery slope of questionable behavior.   A little bit of knowledge about the forces that drive us to cheat can go a long way helping avoid bad behavior. Here are some common landmines to become aware of so you can make sure to defuse them as you embark in a new BA project

The problem with many Unified Modeling Language (UML) educational texts is that they present the various concepts each in isolation; so you see a use case diagram for one problem domain, a class diagram for an entirely different problem domain, and you never get to see the important traceability between the diagrams.

In this case study we aim to put it right by working through a single problem from use cases and activity diagrams, through sequence diagrams and state diagrams, to class diagrams and component diagrams. We have arranged the case study as three distinct perspectives or aspects as follows.

The context diagram and the use case diagram are two useful techniques for representing scope. This article describes two other methods for documenting scope: feature levels and system events.
