2. NEEDLES IN A HAYSTACK<br />

a trimester’s delay should decrease exponentially with time. In other<br />

words, delivery delays hurt the most at the time of introduction. <strong>Later</strong><br />

on, further delays cost less. This result should not come as a surprise to<br />

business people.<br />

What may surprise most people is the second case, improving the<br />

performance in order to keep the same price. The performance enhancements<br />

required from a trimester’s delay go through a bell-shaped<br />

evolution. Naturally as shipments are delayed the performance must be<br />

increased. This increase is larger every year as we approach the middle<br />

of the learning curve. From then onward, however, the product will require<br />

less and less improvement in its performance for comparable<br />

delays. This can be understood in terms of the MIPS/$ growth curve<br />

starting to flatten out after that date, and consequently a slippage in delivery<br />

would require a smaller improvement in performance than it<br />

would have previously.<br />

The Industry Learning Curve<br />

Most industrial knowledge has been acquired on the job. As a consequence,<br />

such knowledge is characterized by unquestionable validity but<br />

also by a lack of analytical formulation. Unquestionable truths are intriguing<br />

because they signal an underlying law. In my search for<br />

guidelines for successful business decisions, I found that mathematical<br />

manipulations of the logistic function yield pairs of relationships between<br />

price and time, performance and time, or price and performance.<br />

While I was carrying out those manipulations I stumbled onto a fundamental<br />

piece of industrial knowledge: the economies of scale.<br />

Economies of scale say that the more units you produce of a product<br />

the less it costs to produce a unit. Production costs decrease with volume<br />

for a variety of reasons: automation, sharing overhead, reducing<br />

material costs through wholesale prices, and general process optimization<br />

resulting from experience acquired while producing. A major part<br />

of the cost reduction can be attributed to learning in some way or another.<br />

The concept of economies of scale is taught qualitatively in business<br />

schools by means of the volume curve, which shows that costs per unit<br />

decrease as a function of the volume of units produced. This curve<br />
