The following are all real answers given in organisations in answer to the question:
“How will we achieve our targets?”
“Improvements in service delivery focussing on services which really matter to customers”
“Ongoing training and evaluation of training needs. Increase in internal quality and accuracy checks.”
“Improved system of recording and reporting performance management data”
“Continuous evaluation of customer’s needs and expectations”
“More detailed inspection regimes”
If you ask a silly question, you’ll get a silly answer. The only real way is to “cheat” to make the numbers, distort the purpose of the system to hit the target or redesign the system to improve it. Failing that there is always magical pixie dust.
