First Claim
1. A method for conducting time and motion studies where an analyst observes and records data for activities performed by a worker, wherein the analyst records the time and event data utilizing a portable computing device having a memory, the method comprising the steps of:
- generating a setup table stored at a workstation and comprising session identifiers and a list of activities, wherein associated with at least one activity is a parameter having a list of pre-selected values;
transferring the setup table to the portable computing device;
generating a graphical user interface for the portable computing device based on the setup table, wherein the graphical user interface presents the activities to the analyst as selectable options;
selecting an activity being performed by the worker from the list of activities displayed via the graphical user interface;
generating a graphical user interface for the portable computing device based on the selected activity, wherein the graphical user interface is limited to presenting to the analyst the parameters associated with the selected activity; and
recording an activity record in the memory, wherein the activity record includes a time reference that represents an elapsed time for the activity and a parameter value inputted into the portable computing device via the graphical user interface.

Abstract
Systems, methods and computer program products are configured for conducting time and motion studies using a portable computing device having a memory, wherein the internal clock of the portable computing device measures the elapsed time for an observed activity as a user (i.e., time and motion study analyst) identifies the observed activity and any associated parameters, counts, measurements or comments via one or more customized user interfaces displayed on the portable computing device screen. The customized user interfaces are generated from data tables created during setup. The elapsed time, activity name, and the associated parameters, counts and comments are recorded in the memory of the portable computing device as an activity record for subsequent analysis.

10. A system for conducting time and motion studies using a portable computing device having a memory, comprising:
-
a workstation including a setup program that creates a setup table comprising a list of activities, wherein associated with at least one activity is a parameter having a list of pre-selected values;
a communication link connecting the workstation to the portable computing device, for transmitting the setup table from the workstation to the portable computing device, wherein the setup table is stored in the memory of the portable computing device;
the portable computing device includes a data collection program for generating a graphical user interface having at least one selectable activity based on the setup table, wherein the graphical user interface presents only the parameters associated with a selected activity; and
wherein the portable computing device includes a memory in which is stored in an activity record having a time reference that represents an elapsed time for an activity and a parameter value inputted into the portable computer device via the graphical user interface. - View Dependent Claims (11, 12, 13, 14, 15)
