The document outlines 4 steps for successful data mapping and identification during discovery: 1) Conduct a thorough investigation of where potentially responsive data is located; 2) Understand who has access to the data as these individuals can help locate additional data sources; 3) Consider data retention, destruction and archiving policies to prevent accidental data loss; 4) Identify hard copies of documents that may supplement electronic data. Taking these steps to map out a data acquisition plan can increase the value of the discovery process and the likelihood of case success.
