5.
Sometimes it’s more complicated solutions
Worried about whether you can afford a
personal loan? With UK interest rates at record
lows, it’s worth checking to see how reasonable
the cost could be.
Whether you need to borrow to buy something,
or you want to bring your existing debts under
one roof, have a look at these competitive deals
we’ve assembled.
Thanks to our Smart Search tool, you can get
an idea of the loans you’re likely to be accepted
for before you proceed with your application.

Changing the
way we work

24.
Data Science can’t happen in a vacuum
Situational Awareness is needed

25.
Your business already has hypothesis for
what creates value
Actively avoid work on anything else
It’s the Corporate Strategy and Objectives
(everyone is aligned behind)

26.
Measurement of everything gives feedback of not just individual deliverables (fast
loop) but also the organisation’s hypothesis of what adds value (slow loop)

Corporate strategy is broken down into many
options (Epics) for Agile delivery

27.
We reduce Batch sizes of work and
have options to keep flow going

28.
Collaboration is key
Shared Buy-in from Senior management
Organizational behavior structured around the
ideal data-journey model
Shared Priorities
Shared Trust in data
Shared Rewards based on measured outcomes,
not outputs

33.
DataOps was popularised by Andy
Palmer in a 2015 Blog post

34.
DataOps is an independent approach to data analytics
Data Analytics team
moves at lightening speed
using highly optimized
tools and processes
across the whole data
lifecycle
Agile Collaboration to
break down silos and
work on “The Right
Things” that add value
Lean Manufacturing like
focus on eliminating waste
& bottlenecks, improving
quality, monitoring and
control
Iterative project management
Continuous delivery
Automated test and deployment

Continuous Operations: Resources that scale

46.
Chemistry is not about tubes
DataOps is not about tools
(but the right ones help)

47.
Align your spine

Principles
Practices

Values
How do you know it is the best
possible tool?
How do you know that
the Practices actively help the system?
How do you know
which Principles you want to
apply?
“We use _____ to get our work done”
“We DO Self-Service and DataOps
to continuously create VALUE for
the customer and business”
We LEVERAGE Agile and Lean
PRINCIPLES to change the system and
make sure resources work on the right
thing
We OPTIMISE for Speed, Accuracy,
Experimentation/Feedback and
Security.
We are here to SATISFY THE NEED to
help customers save money and the
business to execute it’s strategy
It all starts at Needs. Why does this
system exist in the first place?

Avoid building your own anything or
being on the bleeding edge.
Cost of Delay is high.

Modern serverless and managed
infrastructure makes it easy to create
data products just bring code and data
A single unified platform reduces data
fragmentation, overcomes business silos
and helps enforce consistent governance
