| Decomposition | • Decompose the complex task into several simple mini tasks [15]. • Divide and describe tasks due to high granularity [21]. | • Provide guidance on task decomposition. |
| Communication | • Foster an open and supportive communication channel [9]. • Foster efficient crowdsourcing mechanisms [24]. • Appoint employees familiar with the project as copilots to coordinate registrants and answer questions [33]. • Focus on continuous communication, timely reply, and coordination [33]. | • Implement computer-assisted translation or auto-translation mechanisms [13,15]. • Improve the construction of task forums. |
| Schedule | • Pay attention to the progress of crowdsourcing tasks, timely modify and repost the failed tasks. | • Employ empirically machine learning techniques to identify risk tasks automatically. |
