If you're a SMB looking for a cost-effective solution with a great team to support you in implementation, Impraise is a great solution! As you scale, or if your reviews are complex with various cycles during different timelines, this may not be the right tool for you. All and all, they provided flexibility to ensure our folks had productive feedback conversations 2x/year, and also gave folks the optionality to ask/give real-time and regular feedback above and beyond reviews.
Transparency about the capabilities of their system. We would have never chosen WingSpan had we had a clear picture of the limitations of their system.
Ease of use - as an administrator we found it to be difficult to work with. Of course, improvements may have been made in this area since we used it last.
Impraise is a strong tool for smaller teams given their high-touch customer service and flexible product. As you scale and need more integrated, complex solutions, a system like Workday may make more sense for your business.
