The savings _ from using your "in house" expertise _ in terms of money and man_hours alone, will quickly justify the investment you make in "developing the needed skills" _ especially, when you compare what you spend with the cost of purchasing a commercial software application _ or even engaging the services of an Excel VB developer.
VBA is therefore different from the Standalone Visual Basic program used(by professional programmers) for developing commercial quality software applications _ though it borrows many of the latter's features. Think of Excel VBA as being the standalone Visual Basic software, built into Excel for the benefit of Excel users who are not necessarily programmers, but who are keen to exert more control over the application. So, Excel VB offers any interested users the necessary tools to make the application deliver more functionality. The final product is still an Excel document, but with extra functionalities added using VBA.
To elaborate further: A one_page Variable Costs Analysis report sheet automatically generated by the custom spreadsheet application I earlier described, was a powerful tool used by top management to quickly assess performances of individual breweries. Among other benefits, the report made it quite easy to realistically compare sister breweries in different locations(even across countries) based on common denominators. Apart from summarising brewing/packaging materials in two groups _
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.
