I thought it was clear in my original comment that it would require more than one developer before - one for the BI process and at least one for the data-entry component. Given that most BI teams don't have a web developer, that also spreads the process over multiple teams, which can slow down maintenence. And I'm not sure why you think it'd take a whole other developer to manage this tool. BI developers are used to picking up new tools and languages (my BI job requires that I know how to use SQL, python, MDX, and C#, and numerous third-party applications).

And when I'm referring to "old timers", I'm referring to users, not the developers. Why would a user need to understand that snippet? Are we even talking about the same thing?
