A complex system that works is invariably found
to have evolved from a simple system that
worked. A complex system designed from
scratch never works and cannot be patched up
to make it work. You have to start over,
beginning with a working simple system.
Gall’s Law
We cannot replace TurboTax by
creating another complex system
from scratch.

Its great to be here – thank you for having me
Briefly describe your role, background, number of years with Intuit
Technology’s case for change:
The business ecosystem in 2016 moves fast
Today we work in an industry where businesses constantly get disrupted; we need to be agile in order to stay competitive
Applications are moving from desktop to cloud
Big Data is changing technology experiences
Complex user experience
Innovator’s Dilemma: If it makes money, why change it?
With the technology environment today, you can’t rest on your laurels.
However, change is a risk. Innovators have to make a case for adapting.

TRANSITION TO TURBO TAX PRODUCT
HERE TO TALK ABOUT A PRODUCT YOU MAY HAVE HEARD OF – TURBO TAX
BUT FIRST I WANT TO TAKE YOU BACK - BACK TO 1993
CLICK MOUSE FOR 1993 BANNER TO DISSAPEAR
PRESIDENT CLINTON WAS IN OFFICE –
SEINFELD, THE X FILES AND ROSEANNE RULED THE TELEVISION
PETE SAMPRAS WON WIMBELTON
JURRASIC PARK RULED AT THE BOX OFFICE
AND AMERICA FELL IN LOVE WITH BEANIE BABIES
OH, AND THIS WAS ALSO THE YEAR TT WAS FIRST MADE AVAILABLE
TurboTax
We’ve moving to the cloud - e.g. QBO 1 million + subscribers
TurboTax
Built on a 20 year old technology stack
Mobile, web, desktop - with high mobile usage
Advancing our technology was a necessity:
TurboTax has 3 generations:
1st generation – Digital tax forms
2nd generation - Interview-based tax filing questions
3rd generation - Personalized experiences
Advancing our technology was a necessity:
Ex: If you’re an 18 year old barista from NYC, do you collect CA railway requirement?
We need to build product of the future on a platform of the future
Easier said than done

Solving tax is complex.

2 failed prior re-platforming experiences at Intuit, and we’re now on a multiyear journey
Aaron Levie CEO and co-founder of Box… 100M terabytes in the cloud, successfully pivoted from consumer to enterprise by focusing on delighting end customers and providing control for IT.
Rick Dalzell was the CIO of Amazon from 1997-2007…
Andy Jassy at Amazon since 2003. Has led since the early days. Estimated to be $5B this year up from $3.1B last year. Moving faster than any of the competitors.
Existing technology limitations make it very difficult (and often impossible) for us to deliver high-quality, innovative, and responsive products at scale so we can build a durable advantage
Our objective is to lead a technology stack refresh that delivers breakthrough experiences and explosive growth by enabling our workforce to deliver the best work of their lives – and making tax prep obsolete.
Implementing Node: Don’t talk about the benefits, show it
The proof is in the code. We needed to prove Node.js would work, so we ran an experiment.
Intuit “Pirate Ship” example: We built the narrowest slice of tech stack and created a “pirate ship.”
By building an E2E experience in 2 months with PM, PD, UX, and engineers, we proved it would work.
Bridging the new technology to the old technology
Bag on the side vs. Bag in the middle
Example: ACA Intuit
ACA was a new topic for TY 14. We had to ask ourselves: Do we use old or new technology? We took a risk, and decided it would go on the new stack. It allowed us to prove we can build something better on the new stack.
End user example using ACA.
Recap (2 min.)
It’s difficult to create a complex platform from scratch. Start simple and it will evolve to complex.
Break up the monolith one service at a time with Node.js.
Over-communicate the burning platform to developers.
