Abstract: A server for managing overall supply chain and data management and a client for initiating data collection are provided as part of a system. The client can perform data collection operations on the basis of tasks, subtasks and workflows. Tasks can be based on supply chain processes. As data collection is performed, the client is updated to indicate appropriate additional operations that can be performed. Server can be used to design and maintain tasks and operations and can also be used to supply these tasks to the client. Client and server can cooperate in validation of collected data and update of overall supply chain operations accordingly. The system can also be used for carrying out operations other than data collection, such as supply tracking.
