Since the release of PEAF v2 in 2010, it became apparent that some
things that PEAF contained, applied not only to the Enterprise Architecture
domain but to the wider Enterprise Transformation domain. For this reason, POET
was created and the things in PEAF that applied to the whole Enterprise
Transformation domain were moved into POET. In addition, because POET now
considered the wider Enterprise Transformation domain there were new things
that were added to POET.
PEAF v3 was then created by taking the things from PEAF v2 that were
purely concerned with the Enterprise Architecture domain, adding more things,
and restructuring the content to conform to the new structures that POET had
None of this was pre-planned.
A quote from Douglas Adams expresses it nicely:
“I may not have gone where I intended to go, but I think I
have ended up where I needed to be.”
