Method and system for collecting activity-data

A system for collecting activity-data of a user executing a task including at least one activity, the system comprising:

• a hardware user-device having one or more sensing modules to track a location-data;
• a hardware database-server for storing a client-data;
• and
• a server arrangement communicably coupled with the user-device and the database-server, wherein the server arrangement is configured to:
• assign a user a task comprising at least one activity related to a client;
• track the user-device to determine the location-data of the user-device associated with the user;
• retrieve the client-data from the database-server, the client-data comprising at least a client name and an office address of the client;
• determine a change in the location-data of the user-device;
• generate the activity-data based on the change in the location-data, wherein the activity data comprises data related to the at least one activity comprising one or more of a start time of the activity, an end time of the activity, a completion time of the activity, and a nature of the activity, and wherein generating the activity data comprises:
• initiating a correlation of the location-data with the client-data by employing machine learning techniques and generating the activity data if the correlation is successful;
• and
• if the correlation fails, processing a prompt-response generated by a manual-input at the user-device, wherein the prompt-response is generated based on a prompt for the nature of the at least one activity related to the client provided by the server-arrangement to the user-device.
