10 Performance Analysis in the EIS

11 The mission behind Performance Analysis Know your enemy as you know yourself and you need not fear one hundred battles; know yourself but not the enemy, for every victory gained you will also suffer a defeat; know neither the enemy nor yourself and you will succumb in every battle. (Sun Tzu, 652)

48 Case Study 4 Team GB Centralised PA Capture 2012/16 Stafford Murray and Dr. Deborah Sides

49 PA in Team GB House Aim: To Provide (or enhance) PA support to Team GB Sports Centralised capture from OBS feed Made available in variety of ways to suit sport Some sports not allowed to film! Allowed more detailed analyses (HD Footage) Captured what is usually impossible! (Home Advantage)

50 PA in Team GB House 40 Live TV/OBS Feeds 23 Sports using service 16 Capture Stations 17 Hard drives 8 Staff 6 Dissemination Stations 18 x 18 hour days 1 Server 2,500 hours of footage A lot of stressed staff and coaches!

51 PA in Team GB House Did it work? Feedback very positive can actually attribute 4 gold s from service objectively, plus many others subjectively. Next time?

52 Conclusions Applied but science based Questions perennial answers annual Performance Gap driven not technology Soft skills key to success
