From there, we explore the tension between qualitative and quantitative data, uncover the motivational role of data in marathon training, and ask whether clients actually want to talk about training at all.Discover the unexpected metric The Body Shop uses to measure success and get to grips with the difference between leading and lagging indicators. At the end of it all we wrestle with the conundrum of how to use data when some of the things that matter most to workers are the hardest to measure.Let us know in the comments what you measure most frequently.Don't forget to like and subscribe to stay up to date with all our episodes.
