Why Excel Visual Basic _ and NOT Visual Basic? I always answer this question by asking the following question: What would be the point of "Killing A Fly With A Hammer"? Let me elaborate. If a method is available that allows us to achieve the same desired result(s) at LOWER cost, with LESS effort and in LESS time, why should we fail to adopt it? Certain IT persons insist that developing executable applications using the standalone Visual Basic programming language is "better" as it does not limit the user to a particular user application software environment. I concede that this might be a valid point under certain conditions. However, I point out that there are many users who have peculiar needs that do not necessarily require complex solutions. A lot of people today simply want to get their data recording, (re)organisation, and analysis for decision making done quicker and with less effort. They also want to spend as little money as possible to do this. In other words, they want a cost_effective solution that gives them independence from the solution provider in the long term _ without requiring them to undertake laborious skills acquisition immediately. This category of everyday users of technology described above are the ones I believe need Excel VB solutions of the type I describe. One expects that some of these users will over time develop an interest in acquiring advanced skills needed to develop their own solutions in future _ which is why I also encourage them to do so, possibly via self_tutoring, like I did.
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.
For instance if a company had five drink brands in the market but notices that Brand A, which has a profit margin of at least twice the others is in greatest demand, they could (a) focus production efforts on that brand, so that more bottles go out to trade (b) Apply Best Practice/Continuous Improvement initiatives that would result in lower costs of producing each bottle of Brand A so that even though the market price remains fixed, the company is able to earn increasing profit margins per bottle.
At times, they would prefer to click a button that says "Print ABC", or "Print XYZ" report, instead of having to crawl all over the huge spreadsheet(and get "lost" every now and then), to highlight and print different report pages. Using a custom built data entry form to make data entries into 14 different cells in different parts of a table(at the same time/with one click) would, for them, be "heaven" compared to making the entries one at a time.
