Systems and methods for communicating proposals in a task determination system are provided. The task determination system can generate in real-time a set of proposals corresponding to a task. The set of proposals are generated based on a task type and a member profile associated with a member for whom the task is being performed. The task determination system generates a ranking of the set of proposals based on suitability metrics between the task and the set of proposals. Based on the ranking and these suitability metrics, one or more proposals are selected for presentation to the member. The member profile associated with the member can be updated in real-time as the member interacts with the one or more proposals.
