Insightful article from Training Magazine outlines a number of considerations for hiring a training consultant.
Two things stood out. First, begin with a pilot project. At a lower cost and lower risk, a pilot project can project the value, cost and time of a larger project. Second, when asking for referrals, ask for 3 people, then ask for another 3. Call the second set of three. The second set may not have been given the “heads up” and provide more insightful feedback. Any consultant will have 3 clients to vouch for them, but are rarely prepared to name 6 references.
