These apply to all reviews but require extra attention now:
1. Take sufficient time to consider why you want the review/search. Clearly define what you need that a current roster agency or internal group can’t provide. What is working and not on both sides – client and current agencies.
2. Clarity on what type of agency you need and the focus such as data driven, digital first, etc.
3. Think about the long list of agencies that might fit your needs. (Use haystackonline.com as a start point) For media, if you need a global agency of scale, there are a finite number. But for other types of agencies there are thousands and unless your knowledge of the market is current, you need time to explore the universe directly or with help.
