A computer identifies a location that is associated with a task, included in a first list of tasks, based on a first information. The computer determines a first travel time from a second location that is associated with a mobile device to the first location based on a second information. The second information indicates an amount of travel time that is associated with a route from the second location to the first location. The computer generates a plurality of permutations of the tasks included in the first list of tasks. The computer selects a permutation from the plurality of permutations based on the first travel time. The computer generates a second list of tasks using the selected permutation. The organization of the tasks included in the second list of tasks reduces the travel time that is required to complete those tasks.
