This study introduces a Grasshopper tool prototype that empowers designers, researchers, and managers to evaluate a design's possible impact on users, compare design alternatives and alter them to better support teamwork as a desired qualitative outcome. This prototype, called TALCAT, is part of an approach called Functional Scenario Analysis (FSA) developed in SimTigrate design lab where stakeholders articulate their needs in brief plain-language statements, then the design research team turns these into criteria for design and specific metrics for measuring designs. Here we present the implementation of TALCAT in a number of Mayo primary-care clinic layouts to analyze, compare, and dynamically visualize teamwork affordance of layouts to support informed design decisions. TALCAT allows very rapid assessment of multiple metrics and allows what-if-testing of new designs as well as constructing new metrics. Moreover, it can address the validity issue in the field by providing consistency in data collection across multiple projects
