Productivity
P = Outputs
Inputs
,Productivity Measures
• Partial Measures:
• A ratio of outputs to only one input (e.g.: labor productivity, machine
utilization, energy efficiency)
• Multifactor Measures:
• A ratio of outputs to several, but not all, inputs
• Total Productivity Measures:
• The ratio of outputs to all inputs
Labor Productivity
vb:
• Assume two workers paint twenty-four tables in eight hours:
• Inputs: 16 hours of labor (2 workers x 8 hours)
• Outputs: 24 painted tables
outputs = 24 tafels = 1.5 tafels/uur
inputs 16 uur
Examples partial productivity measures
Multifactor Productivity
• Convert all inputs & outputs to € value
• Output: 200 units produced sell for 12.00€ each
• Input:
• Materials cost 6.50 € per unit
• 40 hours of labor were required at 10 € an hour
200 units x 12€ / unit. . = 2400=1.41
200 units x 6.50€ / unit) + (40 hours x €10 / hour). 1700
Interpreting Productivity Measures
• Is the productivity measure of 1.41 in the previous example good or bad?
, Productivity Growth Rate
• Can be used to compare a process’ productivity at a given time (P2) to the
same process’ productivity at an earlier time (P1)
Growth Rate = p2-p1/p1
Example:
• Last week a company produced 150 units using 200 hours of labor
• This week, the same company produced 180 units using 250 hours of labor
Service - Manufacturing
Services:
• Intangible product
• No inventories
• High customer contact
• Short response time
• Labor intensive
Manufacturing:
• Tangible product
• Can be inventoried
• Low customer contact
• Long response time
• Capital intensive
