Custom spreadsheet solutions which survive long after the developer has "left the scene", are often those which users accept because they discover it _ among other benefits _ makes their work quicker and easier to do.

Sometimes people don't really care about learning(or using) all the "cool' advanced functions, formulas and techniques in the spreadsheet application they use for their work. They just want to punch in their relevant raw data _ at any time _ and immediately see the computed results generated by the spreadsheet in a manner that can facilitate their important decision making.
