What data can we dispose of? Organizations need to keep data for 3 reasons: 1) it has business value 2) it has legal obligations 3) it has compliance mandates. All else is eligible for disposal. #dataeconomy
Seems to me that different kinds of data has different value characteristics; Some data is kept to reduce risk (legal or business), some data is retained to help reduce costs; and some is kept to help drive revenue.
As a best practice, we have seen companies: - estimate impact on the business through an ROI and TCO analysis - calculate ROI for each project - reuse the ROI metrics (e.g. % cost savings or revenue increase) to estimate impact on future business
