A few months ago, we received an enhancement request to add three fields to the equipment master file in RentalMan. The request was to add three alphanumeric fields with a length of eight characters each. While reviewing the request, we started asking ourselves the following questions:
-
If we add three fields, why not a hundred? Why not a thousand?
-
What if the requirements change, as they sometimes do, and the fields need to be ten characters each instead of eight? For that matter, what if they need to be a numeric field or a date field?
