The MGI Use Case Note™ describes the ideal customer profile for a given solution. It helps prospective buyers understand a product’s “best fit” by identifying the size, business models, selling regions, tech ecosystems, sales channels, primary verticals, and more of the target customer. The aim is to help interested parties quickly and confidently narrow the list of suppliers that could meet a particular use case. It is not intended to describe the entire range of possible use cases, nor is it an in-depth analysis of the supplier or solution. (For in-depth analysis of a solution, see MGI 360 Ratings™.)
