Exploring business-architecture

Exploring business-architecture

No thanks…
Endless PR intro-slides…?
so let’s do the intro another way…

Hi.
(Yeah, it’s been a while
since I looked like this...)
I’m Tom.

…enough of an intro?
Okay, let’s get on with the show!

what’s that…?
Business-architecture?

- b-o-o-o-r-ing…
It’s the architecture of
‘stuff what business does’

…“can I go to sleep now, please?”…

Nah, c’mon, let’s have
a bit of fun
with this!

…though before that,
we are gonna have to be
just a little bit boring…
(sorry…)

Meet this guy…
(He’s named Charles Hoy Fort.)
(see https://en.wikipedia.org/wiki/Charles_Fort for more about him)

…famed for collecting records and facts
about the anomalous and the weird…
…such as rains of fishes and frogs…

“Whatever theory you have,
there’ll always be something
that doesn’t fit”
and as a journalist and researcher,
his basic principle was…
- sounds kinda familiar, maybe?

What name in your system?
Typical UK-style name-structure for database:
•Title (mandatory: select from picklist)
•Forename (mandatory: 30 characters max)
•Middle-name (optional: 30 characters max)
•Surname (mandatory: 30 characters max)
•Suffix (optional: select from picklist)
Easy, right? – well, let’s take a real example…

UK-style name:
•Mr Pablo Diego Ruiz

UK-style name:
Full legal birth-name:
•Pablo Diego José Francisco de
Paula Juan Nepomuceno María
de los Remedios Cipriano de la
Santísima Trinidad Ruiz y
Picasso

UK-style name:
Full legal birth-name:
•Pablo Diego José Francisco de
Paula Juan Nepomuceno María
de los Remedios Cipriano de la
Santísima Trinidad Ruiz y
Picasso
You probably know him as:

…oops…
Okay, how’s about we try
something simpler?
Driver’s licence, maybe?

Driver’s licence, please?
Real simple, right?
Hmm… maybe
not so simple
after all?
The same for
everyone, surely?
Hensel twins’ driver-licences >>

Driver’s licence, please?
On the flight: One ticket, one seat,
two passengers, two passports
In the car: Two drivers behind
the wheel, each legally liable

…which kinda messes up
our nice so-certain
system-design…
- rats…

“Whatever theory you have,
there’ll always be something
that doesn’t fit”

So how do we find these
‘things that don’t fit’?
- and how do we design for them, too…

Short answer:
Raid the kids’ toy-box!

https://www.amazon.co.uk/Viga-Wooden-Train-Set-49-Piece/dp/B00486QD0S/

Toy-train as
service-metaphor…

…who or what are the various
uses / users of the service?

…how do those uses intersect?

…how might those uses conflict?

…what decisions
need to be made?

…what scheduling /
prioritisation do you need?

…what infrastructure
tolerances do you need?

…how does it interconnect
with other services?

…what disruptions
could careless
users cause?

…what disruptions could the
service cause for others?

…how, where, with what must it
intersect without connecting?

…how might others impact
your infrastructure?

…what impacts could that
have on service-delivery?

…what are the hazards,
potential sources of disruption?

…what happens
when
external risks
eventuate?

…what happens when
the service itself fails?

…what disruptions
could failures cause?

But where does
context come from?
- and why does anything happen?
(in business, anyway…)

A tension exists between what is, and what we want.
The vision describes the desired-ends for action;
values guide action, describing how success would feel.
Why anything happens

A service represents a means toward an end
– ultimately, the desired-ends of the enterprise-vision.
The nature of service

Services exchange value with each other, to help each
service reach toward their respective vision and outcome.
Relations between services

“We create an architecture
for an organisation,
but about an enterprise.”
“We create an architecture
for an organisation,
but about an enterprise.”
Tom Graves, Mapping the Enterprise, Tetradian, 2010
Why architecture?
Organisation aligns with structure, enterprise with story.
We need a balance of both for the architecture to work.

“An organisation is bounded by
rules, roles and responsibilities;
an enterprise is bounded by
vision, values and commitments.”
“An organisation is bounded by
rules, roles and responsibilities;
an enterprise is bounded by
vision, values and commitments.”
Tom Graves, Mapping the Enterprise, Tetradian,
2010
What architecture?
Organisation aligns with structure, enterprise with story.
We need a balance of both for the architecture to work.

If the organisation says it ‘is’ the enterprise,
there’s no shared-story - and often, no story at all.
Whose story?

The minimum real enterprise is the supply-chain
- a story of shared interactions and transactions.
Whose story?

The organisation and enterprise of the supply-chain take
place within a broader organisation of the market.
Whose story?

The market itself exists within a context of ‘intangible’
interactions with the broader shared-enterprise story.
Whose story?

The story is not solely at the whole-of-business level
- we can generalise it to any type or level of context
Whose story?

Services link together in chains or webs, as
structured and/or unstructured processes, to deliver
more complex and versatile services or stories
Supply-chain or value-web

…which brings us to…
a matter
of perspective!
- yeah, which way we look at things does kinda matter here…

Perspectives and journeys
Service-delivery is a journey of interactions
where ‘inside-out’ (the organisation’s perspective)
touches ‘outside-in’ (the customer’s / supplier’s perspective)

Outside-in…

“Customers
do not appear
in our processes,
we appear in
their experiences”
Chris Potts, recrEAtion, Technics, 2010

Every service has its own myriad of stakeholders
Whose story?

A stakeholder
is anyone
who can wield
a sharp-pointed
stake
in our direction…

Who are the stakeholders?
(Hint: there are a lot
more of them than we
might at first think…)

Narrative and story
help us to identify
what needs to happen
- including the exceptions
and uniquenesses…
The role of narrative:

What kind of story?

IMPROVISED
(guidelines and principles)
ANALYSED

“All the world’s a stage”…
Stories underpin every action…

Stories are fractal…
…recursion and fractality within systems and stories
CC-BY-NC-SA gjshepherd via Flickr

Stories within stories, everywhere…

…will User-Story or Job-Story
be enough for all of this?
Short-answer:
useful, no doubt, but probably
not enough on their own
- we’re going to need a broader approach…

Extras are kind of

- they’re not part of the story as such,
but the scene won’t work well

Tom Graves, The Enterprise As Story, Tetradian, 2012

Each segment of a story
is a scene…
- each scene should have
a distinct begin, middle, end
and outcome…

…what’s the story in the scene?

In short…
…we must pay attention
to the story as a whole!
- not just the easy bits…
Context, context, context…

Practical:
Use the NOTES checklist
to assess the story
and its context
What are the respective
needs, trade-offs, drivers?
Identify what is needed to balance the
relations and priorities of all stakeholders.

“The world* is made of stories”
• The enterprise is a story – an overarching theme
• Enterprise as an ongoing story of relations
between people – the actors of the story
• Enterprise-story comprised of many smaller stories
– the scenes or story-lines (aka ‘processes’)
• Enterprise-story takes place in a setting – the stage
and its context, location, props etc
• Stories thrive on tension, conflict and uncertainty
– whereas machines generally don’t…
*‘the world’ including – perhaps especially – the business-world…

It’s easier to engage people
in the architecture
if they can have fun
whilst they’re doing it!
