What problem are we solving?
Typical situation with centralized data teams

Somehow, we didn’t dare to touch the centralized
paradigm of a “single source of truth”

Data as a product

Domain Data
Product
What is my market?
What are the desires
of my customers?
What “price” is justified?
How to do marketing?
What’s the USP?
Are my customers happy?
Applying domain-driven design…
13
Data products belong inside
domains. A domain will
usually contain many data
products that can be used
both within and outside its
domain.
Types of data products:
source-aligned, consumer-
aligned, or aggregate data
products.
Data products don’t operate
in isolation.

Data Products
Domain Teams
Teams own one or more
data products, depending
on the complexity. They
usually sit within a domain.
Teams have long-term
ownership for data
products.
From
● THE data team
● Data pipelines
● Producing data
● Data engineering team
● Data lake / warehouse
It’s a mindset and a language shift,
not an architecture (well, mostly)
To
● WHICH data product team
● Data domains with data experts
● Owning and serving data
● Cross-functional data product teams
● Data product experience platform
Spreading a mindset
Incubate
16
To begin, incubate
a small slice of the
overall operating
model to establish
some of the
foundational
capabilities and
learn from them.
Spreading a mindset
Sustain
17
As the foundations
become
sustainable further
data products can
be introduced.
With each new
products coming
on line the teams
can also begin to
grow.
Spreading a mindset
Sustain
18
As teams learn and
the platform begins
to mature, the
development of
further data
products begins to
accelerate
Spreading a mindset
Scale
19
As data products
scale and mature
the ecosystem
establishes with
increased
interconnectivity
creating new
possibilities for
deeper insight and
collective
knowledge across
the organisation
Thank you!
