Learning Purpose

     


 

Purpose:

To demonstrate a clear linkage between Learning and making Money in Manufacturing Companies,

Purpose:

To demonstrate a clear linkage between Learning and Measurement in Factories,

 

 

also:

To present management levers to increase the rate of making Money,

 

 

and:

To provide a theoretical and emperical underpinning which rationalizes (and makes manageable) the above,

 

 

by using:

The Learning Curve as the central theme.

A Brief History

     




If Cost is a time series, can we fit, predict, and manage it?


In 1936, Dr. T. P. Wright published his affirmative answer:   Cost(t)=Cost(0) * Q-B

where: Q= Cumulative quantity, and B=Slope of the Learning Curve

This remained the dominant view until Dutton and Thomas in 1984 wrote:

Based on our extensive research, B is not a constant, but is based on "causal factors" which are influenced [and, therefore, can be managed - ed.] by the firm’s behavior.

In 1988, Bohn suggested "manageable learning:"   Cost(t)=Cost(0) * e-K * q / ( E *N )

Manageable Learning

     



Cost(t)=Cost(0) * e-K * q / ( E *N )

where:

K is the product of the factors influenced by the firm

 

q is the square root of the cumulative number of experiments, Q

 

E is the quality of the Experimental design

 

N is the total of all of the sources of Noise

 

 

note:

E can be metricized by the average number of experiments it takes to reveal what was being sought in each experiment.

 

 

 

q, K, and N can be further broken down.

Number of Cumulative Experiments

     



q2 = Q = P * D * ( t / C )

where:

q is the square root of the number of cumulative experiments, Q

 

P is the degree of Parallelism ( # of coincident experiments)

 

D is the experimental Duty cycle ( weekly hours experimenting / 168 )

 

C is the experimental Cycle time ( hours between successive experiments )

 

t  is the elapsed time ( the same t as the parameter in the Cost function )

Factors Manageable by the Firm

     



K = T * V * W * S * F

where:

T is the sufficiency of the Technical knowledge and know-how

 

V is the requisite Variety of possibilities ( the probability that the answer is already in the "community" )

 

W is the receptivity of the Working environment to learning

 

S is the cohesiveness of the learning team’s Spirit

 

F is the Fluidity of the learning environment ( the ease with which learners can use tools )
