Lean cycle of service

Cycle time is the time it take to complete your task or piece of the process (washing, loading or drying).
Takt time is the pace at which you need to produce to meet customer demand. It is available working time divided by customer demand in that period of time. Say if you have 5 working hours available to do laundry and you have 10 customers a day that need your services, your takt time is 5/10=. So you need to deliver a clean load every .5 hrs, or every 30 minutes. It is solely a calculated time based on your available working time and customer demand. It has nothing to do with your cycle time which is how long it takes you to perform a task.
The time to wash might be 60 minutes or might be, 90 minutes. In which case you can use your cycle time to calculate how many machines you should have or people washing (if hand washing).
In this case you would CALCULATE the number of resources you need:
(cycle time) / (Takt time) = # of resources needed. In this case 60 / 30 = 2. So you would need 2 machines to meet your takt time.

Facilities (land, buildings, equipment) provide the physical capability to add value and create products. The most common manifestation of facility planning (or lack thereof) is the Plant Layout . An effective layout incorporates and enables the manufacturing strategy on which it is based. Lean strategy starts with workflow and workflow is the result of process and layout. Mr. Lee has authored two books and many articles on Plant Layout and Facility Planning. His approach is organized, practical and systematic.

By creating burn-up lines based on the CFD, you can make rough predictions based on your WIP and Throughput. This allows you to estimate if you’re on track with your planned work and whether or not you can expect to finish the work in a set amount of time. Using a burn-up on a CFD is similar to how a  burn-down chart  functions in the Scrum methodology, while providing additional flexibility. (Tip: Burn-ups work best when applied to a short time period; projecting an average over a longer timeframe will produce tidy, but highly inaccurate forecasts.)
