The diagnosis and prescription was very customized to my business (not just generic, plug and play consulting feedback) All the targets and outcomes were outlined ahead of time to be measurable - which made an ROI outcome very easy to define and measure against. I also appreciated that there was a level of pragmatism in their approach - not just saying "well, the book says..." but really digging in deep to understand my unique business needs - many times the 'Book answer' is a good one, but there can be 5-10% context differentiation that makes your exact use case slightly unique. They never ignored that critical 5-10%.
