We all make decisions based on evidence, whether hard data or personal experience. But are we really interpreting that evidence correctly, or are we basing decisions on hunch and opinion?

In HR and L&D, proponents of evidence-based practice (EBP) encourage us to gather the best available evidence from multiple sources and to weight it appropriately. On this week's GoodPractice Podcast, EBP-enthusiast Mark Hendy joins Owen Ferguson and Ross Garner to share his experience with EBP, as well as tips to get you started.

If you'd like to share your thoughts on the show, you can find Mark on Twitter @MarkSWHRF, Owen @OwenFerguson, and Ross @RossGarnerGP.
