A system and a method are disclosed for self-organizing ad-hoc workflow. In one implementation, the present disclosure describes a self-learning system that monitors input conditions and monitors user steps in executing the ad-hoc workflow. When a new user executes the ad-hoc workflow process, the system receives a group of values for a set of input parameters, determines whether the received group of values has a matching group of values in a database, locates groups of values in the database with at least one matching value of the received group of values, determines a closest match between the received group of values and the located groups of values in the database using importance weights of input parameters in the set of input parameters, and selects the workflow associated with the closest match of the received group of values.
