If it makes money, why change?Complacency = irrelevance Change = risk Innovators Dilemma

Intuit Confidential and Proprietary#Innovators Dilemma: If it makes money, why change it? With the technology environment today, you cant rest on your laurels. However, change is a risk. Innovators have to make a case for adapting.9

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.

Galls Law

We cannot replace TurboTax by creating another complex system from scratch.

How we did it

Learning from the Best Wheelmakers


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 1997-2007Andy 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.22

Everything as a Service

Excerpt from Steve Yegges Google+ Rant

1) All teams will henceforth expose their data and functionality through service interfaces.2) Teams must communicate with each other through these interfaces.3) There will be no other form of interprocess communication allowed: no direct linking, no direct reads of another team's data store, no shared-memory model, no back-doors whatsoever. The only communication allowed is via service interface calls over the network.4) It doesn't matter what technology they use. HTTP, Corba, Pubsub, custom protocols -- doesn't matter. Bezos doesn't care.5) All service interfaces, without exception, must be designed from the ground up to be externalizable. That is to say, the team must plan and design to be able to expose the interface to developers in the outside world. No exceptions.6) Anyone who doesn't do this will be fired.7) Thank you; have a nice day!

Everything as a ServiceTechnology that empowers us and others to quickly create amazing, frictionless experiences

Self-service, leveraging the contribution of others, concept to production in minutes

Customer-back, across Intuit and third-party experiences

Powerful, creating durable advantage


24

Build, test and release services and product experiences independently.I can consume someones service without having to convene a meeting.Services Deliver Speed When Teams can work at their own clock speedServices are built for othersThey have a standard contract.They are scalable and secure.They are discoverable & easy to use.

Attack the Monolith

Intuit Confidential and Proprietary#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.26


Implementing Node: Dont 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 Old & New Technology

Intuit Confidential and Proprietary#Bridging the new technology to the old technology Bag on the side vs. Bag in the middleExample: ACA IntuitACA 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.29

Summary

Intuit Confidential and Proprietary#Recap (2 min.)Its 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.31
