Customer churn and Retention

In any business competitors are always looking to grab your customers, and many customers are on the lookout for a better deal. Customer attrition rates range from 7% to 40% annually in various industries. Slowing this customer "churn" rate by as little as 1% can add millions of dollars to any sizable company's bottom line.

My reply to Avinash Kaushik comment on how useless web analytis reports are

Reports are useless partly because data modeling engineers and business analysts (producing database schema, UIs and Dashboards) can't communicate well with top management or internally, and end up producing tons of random alarm emails that nobody read anymore.

We are running a test, posting made-up, anonymous stellar analytic resumes (from non-existent people) on job boards, to see whether it attracts recruiters and hiring manager.
