It's not enough to have a professional with the technical skills to solve your problem. s/he also needs to have the right attitude and background/experience _ else the relationship will not work. This is where an Excel VB resource is more likely to add value to you. Most Excel VB Developers have backgrounds in management, accounting, engineering and other fields, which further equips them to be useful to you in "thinking up" better ways to apply your spreadsheet automation to get the most value for your business. You therefore need to choose the right developer, with the appropriate background to match your needs.
This last point in my opinion is ONE major benefit you must seek to extract, if you choose to engage the services of a developer. S/he should be able to help you develop (in_house) expertise needed to maintain the application AFTER s/he is gone. If you fail to ensure this, all your cost_savings from using the application might end up being spent paying the developer to maintain the application over time in the future!
Variable Costs Control/Reduction was a strategy that worked extremely well for the company. Most memorable for me as a brewer, was the manner in which huge monetary savings/profit gains were made by successfully implementing variable cost reduction initiatives. For instance, a brewing ingredient switch was made to a more readily available local alternative which was many times cheaper, resulting in phenomenal savings and progressively increasing profit earnings even though the price of beer produced was not raised. This practice was routinely applied across the brewing and packaging processes in line with a well thought out plan.
I am keen to encourage individuals and organisations to explore using advanced MS Excel formulas and functions, in conjunction with Excel VBA programming, to develop customised spreadsheet applications that will solve typical problems end_users encounter daily in trying to record/analyse data and generate reports.
