following discussion takes things down to the next level of detail.
What is an activity?
especially in an STP context, can be defined as the implementation of a
number of business rules. This is illustrated in the following figure:
What are business rules?
Business rules can
be treated as analogous to bits of code or parts of an algorithm – the
behaviour of the system in certain cases.
How do we choose the right business rules?
challenge is to make the rules operable in a generic environment (this is
after all one of our key business drivers – to make schedules generic and
reusable as possible ). In the above figure, some rules will only apply in
certain specific cases, but we want to make the activity definition as
generic as possible.
Therefore rule sets have applicability in much the same as we found
dependency earlier. In fact we can thus formulate an “applicability tree”
to determine at what level to apply the rule set.
This is illustrated
in the following figure where this Rule Set applies to UK Debts
