with production or productivity. The computerisation besides being used for keeping pay-rolls and other such office work, will otherwise be used for inventory control. In this field inefficiencies can be reduced and both the working time of equipment and unnecessary holding of parts can be reduced. This can shorten the circulation time of capital and thus contribute to increasing productivity. But this can at best be a very limited contribution to increasing productivity, as productivity will be constrained by the nature of the technology being used. Inventory control can help to bring actual productivity closer to the limits set by technology employed. It cannot, of course, extend the limits of productivity, something that can be done only by the introduction of a superior technology. Electronification, too, does not have much to do with production and productivity. Electronic weighbridges, for instance, may improve financial results but cannot affect productivity, or the contribution to the economy.
