The document discusses the potential second coming of enterprise architecture (EA) and whether emerging approaches could help re-establish its practical business relevance. It notes that mainstream EA practices have high consensus but little evidence, while emerging practices have low consensus but need a stronger evidence base. The document explores whether EA is losing momentum due to issues with scope, perspective, or lack of relevance to business problems, and poses questions on whether emerging EA approaches could help address these challenges and renew its influence.

… spiritus mundi …
Things fall
apart; the centre
cannot hold;
Mere anarchy is
loosed upon the
world.
Surely some
revelation is at
hand;
Surely the
Second Coming
is at hand.

… nothing is invincible …
“There's a strong product pipeline
coming through the integrated
innovation, and we should be able to
show people not only that we correct the
things they think are tough about
software today, but really bring in
scenarios that they never would have
expected, that we could solve and make
it as efficient as we will.”
(Bill Gates, July 2003)
“... a move from tightly coupled systems
to more loosely coupled
interconnections”

Mainstream practices
have high consensus
but little systematic
evidence.
Emerging practices
have low consensus,
therefore need a
stronger evidence base.

… a connecting principle …
Is mainstream EA perhaps losing
momentum and influence?
Is this a consequence of scope and
perspective?
Or is it because of a lack of relevance
to practical business problems?
So what’s the alternative?
Can emerging approaches to EA help
to re-establish practical business
relevance?
