You will find this article of considerable reading value, if you belong to at least ONE of the following spreadsheet user categories: Owners of Small Businesses _ Restaurants/Bars, Hotels, Hospitals, Factories, Consultants etc; Decision Makers/Job Holders in Corporations _ Materials Managers, Sales/Marketing Analysts, Financial Analysts/Accountants, Project Engineers; And Anyone desiring to make BETTER sense _ and use _ of data!
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.
In addition, an Excel VB developer( who in many cases will tend to be a user turned developer, and is therefore likely to easily see things from your perspective) _ unlike a programmer _ is more likely to be positively disposed to working with you to ensure the application meets your practical needs. S/he will readily understand that the final application is meant to help solve a real problem(s), and will therefore build it to match those expectations.
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.
