Edwina Dunn OBE

Edwina Dunn OBE has spent her 40 years in the IT industry analysing great globs of data and turning it into useful business information to guide businesses.  We call that today the analysis of big data.  She started at the US CACI company which used census data to help customers such as banks and building societies.  She left with her husband after nine years and they formed their own consultancy focusing on analysing customer data.  Their big breakthrough was launching the ClubCard customer service for Tesco which catapulted Tesco to the front rank of UK grocery marketing.  They sold the business to Tesco and formed another company.  She is concerned about the ethics of using data and about the role of women in IT.  Today she took time out from her busy schedule to talk to Richard Sharpe about her life and career.
