Two manufacturers have very different learning rates;one is under 70% while the other is over 80%.What factors might lead to such a gap?

A firm that successfully pursues a steeper-than-industry-average learning curve and manages costs down may still fail if,by underestimating a strong competitor,it fails to gain the added volume necessary for the learning curve to exist.

You are about to undertake manufacture of a labour-intensive electronics component.The first unit took 300 hours.You are not sure whether the learning rate is 70% or 80%.The initial phase of the contract calls for 6 of these components. a.How much time will it take to complete all six at 70% learning? b.How much time will it take to complete all six at 80% learning?

A small manufacturer that offers "hand crafted" furniture has developed a new style of desk that they believe will be very successful in the marketplace.It is expected that the first desk will take about 60 hours of craftsmen's time to complete.They expect a 90% learning curve for this desk. How long will it take to make the 20th desk? The firm is considering accepting an order for 25 desks.How many hours of labour will this require for all 25?

If the learning rate for a process is 80%,that same process has a 20% ________.

Your firm has expertise with a special type of hand-finished furniture.The learning rate is known to be 82%.If the first piece of furniture took 6 hours,estimate how long it will take to complete the third unit.

Learning curves are based on the premise that people and organizations become better at their tasks as the tasks are repeated.

Companies pursuing a learning curve strategy must increase

Failure to consider the effects of learning can lead to ________ of labour needs.

The learning curve rate is

A defence contractor has just started producing turbines for a new government contract.The first turbine took 7000 hours to produce.If the learning curve is 90%,how long will it take to produce the 10th turbine? (Use at least three decimals in the exponent if you use the logarithmic approach. )

The fact that human activities typically improve when they are done on a repetitive basis is described by a

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 10th unit? (Use at least three decimals in the exponent if you use the logarithmic approach. )

A certain product under development took 200 hours for the production of its 2nd unit and 180 hours for its 4th unit. a.What is the learning rate? b.How much time did the first unit take? c.How much time would the production of the 10th unit take? (Use both the logarithmic and the Table E.3 approach.Do the two versions agree?)

The earliest industrial application of learning curves came from a report by ________.

When learning curves are plotted on ________ scales,the "curves" become straight lines.

Joe's Manufacturing is considering bidding on a small order for 5 units.Based on similar products that they have made in the past,they believe that the first unit will take 500 labour hours.They also believe that there will be an 80% learning rate.How many hours of labour should Joe include for his bid?

Which one of the following courses of actions would not be taken by a firm wanting to pursue a learning curve steeper than the industry average?
