Throughput at IBM corporate cafeteria checkout stands was slow, and
there was a concern with petty theft. People were hiding candy in
areas the cashier could not see, and they were spending excess time
counting change and putting it away before moving on.
Through detailed time and motion studies and system redesign, we
improved cashier throughput at all IBM corporate cafeteria facilities
by designing and integrating a new commercial point of sale workstation
and checkout configuration.
Solutions to this problem involved user surveys, requirements definition,
field analysis, time-line task analysis, detailed system design, and
integrated system prototype fabrication and evaluation.
