Electronic discovery is the process of identifying, preserving, reviewing and producing electronically stored information that is relevant to a lawsuit. It involves getting electronic systems in order to mitigate risks and expenses from initial creation of information through final disposition. The key steps in electronic discovery are identification, preservation, collection, processing, review, analysis, production, and presentation. Selection of retention software and electronic discovery solutions depends primarily on cost considerations such as identifying systems, preserving files and metadata, processing data, enabling searches, and producing documents for external review.
