2. FUNDAMENTAL AND INCIDENTAL
INTERACTIONS
• Most likely a different person or group will be
assigned to design each chunk.
• Because the chunks interact with one another
in both planned and unintended ways, these
different groups will have to coordinate their
activities and exchange information.
• In order to better manage this coordination
process, the team should identify the known
interactions between chunks during the
system- level design phase.

3. There are two categories of interactions
between chunks.
• First, fundamental interactions are those
corresponding to the lines on the schematic
that connect the chunks to one another.
• Second, incidental interactions are those that

arise because of the particular
physical
of functional elements or
becauseof the geometric arrangement of
the chunks.

INTERACTIONS

4. • While the fundamental interactions
are
explicitly represented
showing the
clustering
by the
schematic of
elements into
chunks, the incidental interactions must be
documented in some other way.
• For a small number of interacting chunks
an interaction graph is a convenient way
to represent the incidental interactions.
