The first unit of a product took 832 hours to build,and the learning curve is 75%.How long will it take to make the 30th unit? (Use at least three decimals in the exponent if you use the logarithmic approach. )

What cautions are in order when using learning curves?

The learning curve may not be permanent;it can be disrupted by changes in process,personnel,or product.

Learning curves have a variety of purposes,which can be placed into which of these broad categories?

Your firm has a contract to make 20 specialty lenses for night vision equipment.The first one took 40 hours.Learning is expected at the 85% rate.How long will it take to finish all 20 units?

The first unit took 10 hours and the fourth unit 8.1 hours.What is the improvement rate?

It took 18 hours to complete the first two products with an 80% learning curve.How long did the second product take?
