Both law firms and corporate legal departments occasionally need assistance evaluating the legal technology market for a particular type of solution and selecting the right tool for a job. This assistance is especially useful to law firms that do not have internal innovation teams tracking the market. Consultants who provide technology procurement services are able to provide advice about which products and solutions to evaluate when looking for a certain functionality or trying to solve a particular problem, how to evaluate these solutions, what questions to ask, how to develop requirements and prioritize attributes of the various solutions. They are often also able to help law firms build a business case for investment and provide advice about running a pilot and driving adoption of the relevant technology.
