TL;DR: The results imply that the flexibility of the Web and Web search engines allows different users to complete different search tasks successfully, however, the search techniques used and the efficiency of the searches appear to depend on how well the individual searcher fits with the specific task.
Abstract: Users' individual differences and tasks are important factors that influence the use of information systems. Two independent investigations were conducted to study the impact of differences in users' cognition and search tasks on Web search activities and outcomes. Strong task effects were found on search activities and outcomes, whereas interactions between cognitive and task variables were found on search activities only. These results imply that the flexibility of the Web and Web search engines allows different users to complete different search tasks successfully. However, the search techniques used and the efficiency of the searches appear to depend on how well the individual searcher fits with the specific task.

TL;DR: In this paper, the authors propose that group members' shared task representations play an important role in this respect, because groups are often insufficiently attuned to the task's information elaboration requirements.

TL;DR: In this article, the effects of group size and task characteristics (production, discussion, and problem solving type tasks) on group performance and member reactions were assessed, and it was found that dyads tended to be most satisfied and dissatisfaction increased in approximately linear fashion for larger groups.
Abstract: The effects of group size (2 through 7 members) and certain task characteristics (production, discussion, and problem solving type tasks) on group performance and member reactions were assessed. Subjects were students at two universities who performed three 15-minute tasks. Results showed that size had negligible effects on performance characteristics and strong effects on member reactions. Dyads tended to be most satisfied, and dissatisfaction increased in approximately linear fashion for larger groups. Type of task strongly affected both performance characteristics and member reactions. Contrary to expectations, there were no substantial interactions between size and task type in predicting member reactions or group performance. Several implications of the results were discussed: (a) the uniqueness of dyads in comparison to other groups sizes; (b) the question of what is the "optimal" group size; (c) the means by which the strong effects of task type may take place; and (d) questions raised by the finding that some substantial differences were obtained for subjects run at the two different universities. Many of the most obvious-and most potent-determiners of group behavior are, ironically enough, also among the least investigated and least understood in the group psychology field. Several reviewers (e.g., Golembiewski, 1962; Collins and Guetzkow, 1964; McGrath and Altman, 1966) have documented the dearth of systematic knowledge about two such factors: group size and the nature of the group task. Clearly, both group size and task characteristics should make differences in the ways people interact in groups and in the kinds of reactions they have to the group experience. The scattered empirical work which has in

TL;DR: In this article, a method is described for managing a plurality of tasks to be carried out by a majority of personnel, each of the tasks having identified task details relevant to the task and each task having a task personnel who will be directly involved in carrying out each task; allocating sole responsibility for each task to a task controller, and transferring task details to and/or between task personnel and controllers such that task details are provided to and accessible by only the task controller and the task personnel for the task.
Abstract: A method is described of managing a plurality of tasks to be carried out by a plurality of personnel, each of the tasks having identified task details relevant thereto, in which the method includes: identifying task personnel who will be directly involved in carrying out each task; allocating sole responsibility for each task to a task controller, and transferring task details to and/or between task personnel and controllers such that task details relevant to a task are provided to and accessible by only the task controller and the task personnel for the task; wherein recommendations for modifying task details relevant to a task can only be made by task personnel for the task, and wherein a task or task details for a task can only be modified by the task controller for the task and/or an administrator; the method utilises a data processing assembly operable under the control of program means embodied on a machine-readable storage medium that provides a task management system for coordinating the plurality of tasks, and the task management system includes: transfer means for transferring the task details to and/or between the task personnel and controllers; recommendation protocol means for establishing a protocol that the recommendations for modifying task details relevant to a task can only be made by the task personnel for the task, and modification protocol means for establishing a protocol that the modifications to a task or the task details for a task can only be made by the task controller for the task and/or the administrator
