Lean and cycle 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.

Mike,
Your calculation for takt are absolutely right taking an average demand is the wrong part. We take maybe a six month look ahead in orders that is the customer demand. Takt may change up to 8 times a year on some value streams.
In aerospace we had 9 different aircraft types one would be on a move rate of three a week some one a month each had an individual takt time based on the demand for that  product.
The cycle time of each key stage or process was then evaluated if it was greater than takt you had to in goldratt terms exploit the constraint. You would create a yamazumi or line balance chart to identify the constrained stages from seeing this you can do many things .
Identify Value and Non Value add. eliminate the waste to get below takt. Introduce shifts on some stages or create identical stages called rate tooling. So you never under or overproduce as you are asking because the speed of your line increases and decreases with customer demand by flexing tooling positions and manpower.
Usually you had the luxury of one value stream getting faster as another slows down moving your manpower onto different contracts.
Hope you get this
All The Best

In addition, the United States Government has recently begun to employ lean startup ideas. The Federal Chief Information Officer of the United States , Steven VanRoekel noted that he is taking a "lean-startup approach to government." [40] Ries has also worked with the former and current Chief Technology Officers of the United States — Aneesh Chopra and Todd Park respectively—to implement aspects of the lean startup model into the United States Government . [41] [42] In particular, Park noted that in order to understand customer demand, the Department of Health and Human Services , recognized "the need to rapidly prototype solutions, engage customers in those solutions as soon as possible, and then quickly and repeatedly iterate those solutions based on working with customers." [43] [44] In May 2012, Ries and The White House announced the Presidential Innovation Fellows program, which brings together top citizen innovators and government officials to work on high-level projects and deliver measurable results in six months.
