The 7 Habits of Highly Effective Performance Teams [PerfNow 2019]

Over the past year, I've talked with companies of all types – retail, media, travel, software, and more – and all sizes – from SMBs to huge enterprises. I was inspired to see how different organizations approach creating a robust performance culture.

• Prevent regression
• Reduce gatekeeping
• Increase investment from the business

In this talk at the performance.now() conference in Amsterdam, I shared tips and best practices gleaned from scores of conversations with people and companies who are leading the way down the path to performance.
