The assignment was not an accident. Before being redeployed to Benin brewery, I had been involved in "validating" the numerous complex formulas in the custom Lotus 1θι spreadsheet application during its development. The author _ Richard Chambers _ was at the time in charge(as Training Coordinator) of training new entrants, and upon discovering my keen interest in learning, often gave me his laptop to "proof" formulas, links etc. It was he who had told his counterpart in Benin brewery(Joe Sheehy) that I could help out with a problem they were having using the application. And I did resolve the problem _ resulting in my subsequently becoming responsible for the reports collation using the application.
The 80ᚼ Pareto principle is based on Pareto's theory that 80% of the results one gets in a particular endeavour will be mainly due to 20% of areas to which one has applied efforts. In business this principle has been found to be true. Your data, properly converted into appropriate performance indicators, will show you where your largest margins come from. You can then channel more time and effort in that direction.
I believe the foregoing are compelling justifications for choosing Excel Visual Basic over Visual Basic.
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. Cost per Hectolitres brewed(One Hectolitre = 100 Litres), to know if the brewery had stayed within the approved upper limit of spend(plotted as a straight line target across the same period) or not. 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.
