How Can We Improve This Article?

The charts below (Towels & linen and Energy are used in this example), displays whether your plan shows year-on-year (YoY) improvement, considering the activity levels.   The plan values for each month are divided by a relevant productivity measure such as guest nights or hotel area in square meters and compared to the same calculation for the same month last year. It shows improvement (a reduced cost per guest night) where the blue line is lower than the gray one.  Note that the blue line will update as you make changes in the data table on this page. You can also switch between alternative charts by selecting the gray dot below the chart. Hovering over any value will display the exact value shown for that month.

The same applies when choosing Chemicals, Food waste, Water and so on.
