Time-Booking

The clock card is required, essentially, for the correct determination of the
amount of wages due to a worker on the basis of time he has put in the factory. It merely
records day by day and period by period the total time spent by each individual worker in the
factory. But it does not show how that time was put to use in the factory—how an individual
worker utilised his time in completing jobs entrusted to him and how long he was kept waiting
for one reason or another due to lack of work, lack of material and supplies, lack of
instructions, machine breakdowns, power failures and the like. These are all vital pieces of
information necessary for the proper collection of cost data and for effective controlling of
costs. For the collection of all such information, a separate record, generally known as Time
(or Job) card, is kept.
