Sherri Adame, enterprise metadata management leader at Cigna, describes Cigna’s data lake project in terms of its data governance journey and provides insights into some of the business pain points/drivers, organizational change, and best practices associated with Cigna’s new data governance process.
By 2015 – when they were already 4 years and 100s of data sources into deploying their enterprise data lake – CIGNA’s Chief Data Office realized they had a “swamp” problem.
Business users were struggling to find data in the lake and understand what it meant. CIGNA’s cyber risk team was worried sensitive data might be making into the lake without appropriate encryption and access controls. And the multitude of teams whose job it was to get new data into the lake, including data architects, stewards, modelers and BI experts, were having a hard time working together efficiently to deliver new data into the lake fast enough to meet the business’ needs.
The problem was metadata – or more specifically lack of it.
CIGNA’s data lake was well stocked with data but lack of metadata describing that data was creating a wide range of usability, access, security, transparency, and governance problems.In this presentation Sherri Adame, enterprise metadata management leader at Cigna, describes Cigna’s data lake project, outlines their use of Podium Data’s data lake management platform, and provides insights into some of the business pain points, organizational change, and best practices associated with Cigna’s new metadata driven data governance process.
