It is useful to create a list of all commonly used information in the business to improve productivity and assist staff with client queries, form completion, and other administrative tasks. How often do you waste time searching for the ABN or fax number? Stick it in a handy place and allow it to evolve. Personally I have stuck the chart on the inside of my data entry folder, so it is easily available when data is being entered. There is probably lots more useful data that could be included on the list, and I welcome your suggestions below.
