'It is a capital mistake
to theorize before one has data. Insensibly one begins to twist facts to suit
theories, instead of theories to suit facts.'
- Sherlock Holmes, A Scandal in Bohemia
I’ve always loved
this quote from Sherlock Holmes. I used
to battle this every day (much less now) when I was starting my data analytics journey. Old assumptions die hard. Just because it happened before, or we
observed a fact, it didn’t mean that was the answer forever. New data and new facts can change
assumptions, and if we’re lucky, change our direction if we can spot it early
enough.
Luckily I’m several
years into my data journey, and don’t have to press (as much) when I say we
need to look at the data. I believe it’s
because I’m at the center of an organization that has successfully endured a
cultural shift in regards to understanding the importance of interpreting the data,
using it to make good decisions.
I recently came across
a study published by IBM's Center for Applied Insights titled: Breakthrough
experiments in data
science: Practical lessons
for success. I wish they had published
this when I began my journey, it might have made it a bit less bumpy. I’ve decided to look at the main points and give
my comments on the practical advice from the researchers.
1.
Infuse data science into the
culture
This wasn’t easy, but I agree is of paramount importance. Your organization has to come to a point
where the trust in the data is essential because they use it to make decisions
for their business. Having the mindset
that “how will we capture the data on this new process so we can learn from it?”
will take you a long way to success.
2.
Design a data science capability
This seems like a no-brainer, but it is so important to success. How
are you capturing data? What sorts of governance
have you applied? Have you started with
the end in mind? Data is so valuable,
and so important to good outcomes, that having a good foundation program
capability will set you up for later breakthroughs.
3.
Equip with the right technology
I love spreadsheets. I cut my
analytics teeth using Excel (okay, Lotus 1-2-3) and various add-ins. They work
well, but aren’t the best tool in all cases.
They require a lot from the user in order to manipulate the data for the
desired outcome. I’ve found that statistical
tools like SPSS and Watson Analytics can do a lot of heavy lifting when trying
to analyze data without a lot of (comparatively speaking) work.
4.
Showcase your results
Who doesn’t like to say “I told you so?” Maybe not the best attitude to win over
converts, but you get the idea. There
are so many anecdotal examples that companies run for long times on that it
becomes something not to question. One
thing I’ve learned is that big prizes are to be won when we question orthodoxy. What better way to do it than with data? People don’t know what they don’t know. It’s the data scientist’s job to do just that.
