Having carpenter’s tools (even the best tools) does not mean someone can build a house. Likewise, training someone to read a spreadsheet does not mean he or she can build a financial plan for their department. Or, knowing how to prepare a presentation does not mean he or she can convince customers to do business with you. Sharpening people’s skills does not automatically mean they can deliver results.
Specifically, what are you doing to orient staff development to increasing effectiveness? Yes, results? Do you know what works? How? Do you know what doesn’t work? What now?
