Modern business constantly strives for maximum efficiency. This has come to mean that every business system is algorithm based. Algorithms feed information to other algorithms, which spit out numbers that are used by the human interface, to make as much money, as quickly as possible. The weak link is that the algorithms rely on computers to work properly, or they stop doing their job. There is rarely an analogue back up system available, so if the computers go down, everything stops. At the company I work for, we have a very good Enterprise resource planning system, that takes input data from all the bits of the company, chews up the numbers, and spits out how many of each thing we make, needs to be made, and sold, in a given time, to maximise income. It relies on the input data being correct, and the computers all working correctly, or it’s a nightmare. That’s the way of the world we live in now though.
