This guide outlines a structured framework for assessing the feasibility of potential Geographic Information System (GIS) solutions, including maps, applications, and integrations. It details the Prototype service, which allows organizations to test the viability of their GIS solutions in a controlled environment. The document explains that implementing a GIS solution can present various technical and operational challenges that may not be apparent during early development stages. By utilizing a low-cost, low-risk prototyping approach, organizations can define the scope of their GIS solutions, identify potential challenges, and refine their requirements before committing significant resources. The guide emphasizes the importance of understanding the feasibility and value of a GIS solution early in the process to avoid unnecessary costs and ensure alignment with organizational needs. It also describes the phases of the prototyping process, including initial ideation, building and testing the prototype, and presenting the testing results.
