Abstract: In some examples, a method involves rendering a graphical user interface having an Assignment Map canvas for specifying an Assignment Map, the Assignment Map graphically representing configuration data for a set of one or more user devices. User input specifies a set of conditional logic blocks at respective graphical positions within the Assignment Map canvas, each conditional logic block comprising one or more conditional logic nodes, each conditional logic node having a respective assignment rule and a respective set of Library Items. For each user device, the set of conditional logic blocks are evaluated in an order determined by a relative graphical position of each conditional logic block along a root line within the Assignment Map canvas. Each user device is then configured using respective configuration data generated based on an evaluation outcome of the plurality of conditional logic blocks.
