How many 'things' do you find yourself re-doing and it takes up so much brain power each time you do. Simple tasks, admin tasks, basic functions but each time you do it, you do it from afresh each time.
Think about the return on the investment...consistent training, ongoing review against benchmarks & standards set, consistent outputs, higher service levels, better client retention, but also consider the personal aspects...less frustration, less headaches, less repeat, repeat, repeat and more LEVERAGE!
