So this is the domain core of the use case.
The second alternative essence is shorter than the other possibilities. It consists
of only four steps. It is more abstract and omits more information. The best
way to fi nd out whether or not this is still suffi cient are the reactions of the other
project participants. Do they all understand the essence, or do you have to explain
what is meant every time?
The way between the purely essential description and a more pragmatic
description, which is normally sprinkled with technical details, is a tightrope walk.
If you move too sharply to one side you risk ??? falling down. ??? Once you ??™ ve understood
the degree of abstraction and the benefi ts of an essential description you
will easily fi nd the right way.
The number of essential steps naturally depends on the domain situation
and cannot be universally stated. As a heuristic: there are at least two steps and
at most eight steps in most cases. You should review the essence if your number
differs a lot.
You will describe each of the essential steps in more detail later on in the
approach.
