The document discusses the benefits of adopting a portfolio management approach to e-discovery projects over the traditional case-by-case approach. It notes that while each case may be unique, there is significant overlap between cases in terms of documents, custodians, and tools used. A portfolio approach acknowledges this overlap and allows organizations to minimize redundant work, avoid duplicate data collection, and reduce total data storage needs. It emphasizes establishing consistent, repeatable processes and leveraging the same technologies across all projects to cut costs and work more efficiently. The document also provides considerations for implementing a portfolio solution and ensuring any tools adopted are secure, cost-effective and able to meet both current and future needs.
