Important Background information:
The most well known kind of technical (internal) economy of scale arises
because the capacity of a small set of technical units frequently rises
in greater proportion than their cost as the set of technical units
becomes larger. This technological relationship is of prime importance
and is known as the six-tenths rule.
The “six-tenths rule” stated mathematically is:
C2 = C1 [Y2/Y1]0.6
Where:
C1 is the total cost of a small set of technical units
C2 is the total cost of a larger set of technical units
Y1 is the capacity of a small set of technical units
Y2 is the capacity of a large set of technical units
In the six-tenths rule a technical unit is the unit cost of say:
A software package
A personal computer
A microprocessor
An oil tanker
An EPOS
