in the mono-supplier companyA situation,
support person Sa (contacted by the client)
has to talk to engineer Ea:
client ↔ Sa ↔ Ea.
the intra-companyA Sa ↔ Ea channel (which may
be more involved than that) is, presumably,
where epsilon applies.
and similarly for mono-supplier company B:
client ↔ Sb ↔ Eb.
in the different supplier situation it'd be
client ↔ Sa ←...→ Eb.
the question is what is the inter-companyA↔B
channel ‘←...→’? who is involved? and how
many steps? the chain could be, for instance:
client ↔ Sa ↔ Ea ↔ Sb ↔ Eb.
leading to epsilon² but that's clearly not
the only possibility. (nor do I consider
it even a likely one.) I suspect a more
probable chain is not unlike:
client ↔ Sa ↔ Ea ↔ Eb.
that is, there is an engineer-to-engineer
backchannel, so once you can get through
to that “engineering network” things can
go much more smoothly.
or in short, it does not follow that ‘←...→’
necessarily leads to epsilon².
the above assumes the client only has to make
one call. in the far-too-common case of buck
passing (each company blames the other), then
there are multiple calls by the client (at
least one to each company), which very easily
winds up being far worse than epsilon².
