This article is meant for those individuals/businesses who sometimes experience a need to use their spreadsheets in the (somewhat "impersonal"?) manner described above, to get the results they want. That need would often arise out of their lack of requisite skills to get the spreadsheet to behave the way they want _ or limited time to devote towards incorporating necessary automation to make it do so.
To experience the type of automation I refer to, you can email FREE demos of sample automated Excel VB driven spreadsheet applications like Ƒ) a Training Tracking Database(TM), ƒ) a Fiveƕ) Year Income & Expense Monitor(TM) or Ɠ) an Export Packing List & Invoice Generator(TM) to yourself using the file mailer on my website.
The visiting head of the technical function only needed to look at the most recently plotted point on the chart (relative to preceding ones) for a Key Performance Indicator like.

Discussions would then take place based on identified "Exceptions"(which could be "good" e.g. savings made or "bad" e.g. monetary loss due to materials over_used), and "Actions To Be Taken" to correct or maintain observed performances agreed upon.
You can choose to learn how to do it yourself _ or call in someone(an Excel VB Solutions Developer for instance) who knows how. Again, this would be dependent on your purpose, how proficient you are, and/or how much time you have at your disposal. Ultimately, even if someone develops a custom application for you, it should happen with YOUR guidance at every point to ensure that it does EXACTLY what you want it to do, and that you can easily _ with your developer's support/coaching _ learn how to make modifications to it in future, without needing to call back your developer.
