Very similar analytics work takes places in the telecom industry with respect to customer churn. However, this typically requires a large data size for it to be accurate. So, I wonder how many companies are large enough to benefit from it. On a larger note, I wish "managers" used other simple means like talking to people openly about their aspirations, instead of blindly following the processes laid out by the company. Thankfully I don't work in such a place - but most big corps could just do better on the attrition rate if they made their appraisal process more employee friendly, focussed on encouraging a open culture and reduced needless hierarchy.
