What is Applied IT

To remind ourselves what Applied Information Technology is, we need to go back in time to the start of the 1980’s. At the start of this decade we witnessed the creation of two innovative products which gave birth to the information technology industry. The first product is the Apple II microcomputer, which introduced the world to the concept of personal computing. The second product is Visicalc, the spreadsheet software. Visicalc is the original spreadsheet. Nothing of it’s kind existed before.

The combination of these two products brought computing into business management. The Apple II made computing affordable. Up until the early 80’s, computing was a privilege of academia, the military and extremely rich corporations. The machines were huge mainframes which were utilised on a time share or booking system. What ever resources you used, you were billed for. The apple II was different, it sat on your desk and was all yours for just $3000.

Visicalc screenshotVisicalc is the invention of a Harvard Business school student Dan Bricklin. Bricklin wanted a method to make financial calculations as effective as possible. The most effective way at the time was to use large blackboards ,some even spanning several rooms, which were divided into a matrix. Each cell in the matrix was identified by coordinates. Here is the back breaker. If you changed or added any values to any cells. This meant you had to recalculate potentially hundreds of cells on the blackboard. This meant rubbing out values and then chalking in the new values, hoping that you have got your math right. Visicalc became the virtual blackboard with instant answers, and no more rubbing out and chalking in of values.
Visicalc enabled experimentation and “What if Scenarios”. Calculations now take seconds rather than hours. This allowed the business manager to model the finances of the business and quickly make commercial decisions based on how the model reacts. “What happens when my supplier increases costs during summer months?”, “What will my operating costs be when I increase production by 5%?”, these are the sort of questions that could be answered in seconds.

In my view, this is the essence of information technology. This is information technology being applied. An everyday task has been revolutionised and made trivial. The benefits are clearly visible:
