You're getting dangerously close to my favorite design approach - which
really starts with requirements elicitation - namely, Ian Graham's SOMA
method(ology). He advocates considering the system as interacting with
people (or other computer systems) via a series of (abstract) messages. The
messages convey some data and a request, the return provides data or
confirmation or whatever. It is the responsibility of various tasks to
accomplish the golas of the messages.
These tasks may - or may not - end up getting implemented by some set of
objects in the O-O sense.
This could tie in to your earlier post in that a person asks the system for
certain data (reports) - that might when generalized become a requirement.
