Abstract: Techniques are described for assigning users to swarms based on skill and generating recommendations for increasing skill proficiency. In some implementations, a request specifying a set of requirements for completing a task includes at least one required skill, optionally in combination with a required minimum proficiency value(s). Metrics can be generated based on statistical analysis of instances in which a task is at least one of: (i) assigned to a user who is not associated with a required skill, (ii) assigned to a user whose proficiency value is below a required minimum proficiency value, or (iii) assigned after a delay due to unavailability of a user who is associated with a required skill. The computer system can identify a first skill for improving the metrics, identify a user for becoming associated with the first skill, and send a notification recommending an online learning resource relating to the first skill.
