The enterprise data warehouse (EDW) at Intermountain Healthcare went live in 1998. The EDW at Northwestern Medicine went live in 2006. Dale Sanders was the chief architect and strategist for both. The business inspiration behind Health Catalyst was, in essence, to create the commercial availability of the technology, analytics, and data utilization skills associated with these systems at Intermountain and Northwestern. Lee Pierce assumed leadership of the Intermountain EDW in 2008. Andrew Winter assumed leadership of the Northwestern EDW in 2009, and transitioned leadership of the EDW to Shakeeb Akhter in 2016. This webinar is a fireside chat among friends and colleagues as they look back across their healthcare IT decisions to answer these questions:
What did we do right and what did we do wrong?
What advice do we have for others in this emerging era of Big Data?
What does the future of analytics and Big Data look like in healthcare?

I learned what was right by first doing what was wrong.
Luckily, I watched others do what was wrong and learned from them
without suffering their wounds as mine.

What did we do right?
โข Hired a balanced combination of social skills, domain skills (clinical and financial),
and technical skills
โข Good balance of centralized/decentralized development of these skillsโฆ 60/40 split
What would we have done differently?
โข Overlooked the cultural issues of โdataโโฆ threatened legacy source systemsโ
teamsโฆ Intermountain the IDN vs Northwestern the AMC
โข Too much dependence on matrixed technology resources, esp DBAs and Sys
Admins who were skilled in transaction databases, not analytics
What are we thinking about the future?

What did we do right?
โข Hired amazing data professionals - dedicated, smart, committed - treated them right
โข Embraced early support from business and clinical leaders that allowed us to start
early: Dr. Brent James, Dr. Homer Warner
โข Partnered with & empowered the data analysts to be primary producers of analytics
โข Engaged business leaders in Data and Analytics strategy and execution
What would we have done differently?
โข More thoughtful and coordinated growth, hiring of data analysts across the business,
earlier job description standardization and smarter growth
โข More bold steps to organize analytics as centrally managed, locally deployed
What are we thinking about the future?
โข Improved data literacy for leaders = how to ask for analytics help, how to use
insights to improve decision making and change business processes = value

What did we do right?
โข Small, highly skilled team at the start resulted in agility and faster product to market
โข Multiple tangentially related functions developed within the EDW team that resulted
in self-sufficiency
โข Recruited EMR Application Analysts with exposure to Business Intelligence
What would we have done differently?
โข Develop additional roles to accommodate growth and scale with the organization
โข Recruit clinical and operational SMEs to assist with understanding of data
What are we thinking about the future?
โข Develop specialized roles in order to scale for future growth
โข Blur the lines between EDW & Analytics via hybrid resources

The primary goal of Data Ops is to achieve Customer Satisfaction with DataAssets &Analytical
Solutions across the enterprise
โข Standardization: Establish standardized tool sets and
processes to increase productivity of data teams
โข Cross-Functional Teams: Break-Down silos within data
teams (EDW/Analytics) by establishing cross-functional
teams consisting of Data Architects, Analytics Consultants,
Report Writers, ETL Developers and Data Scientists
โข Customer-Focus: Increased alignment with customer
focus and priorities by establishing customer-centric
product teams to serve data needs for operating units and
system functions
โข Value-Add: Provide continuous delivery of analytical
insights to enterprise customers in order to establish a
data-driven culture

โข Purchased and implemented Tableau
โข Resisted ongoing pressure to move data to canonical data models (i.e. Oracle genomics)

vs. value realized
โข Build more meaningful working relationship between EMR vendor(s) and healthcare analytics
programs, focus on opportunities to deliver value through analytics
