3. Hi-Tech Housing  Started:1991  Location:Bristol, IN  Home types:HUD Code and modular  Price point :Mid to high-end  Design:Substantial customization  Production:2 to 4 floors/day  Market area:Midwest

4. Partition Build  Wall build cycle time too long  Not keeping up with wall set  High visibility area

5. Partition Build  Replenishment  Equipment  Appearance No designated storage locations and consumed floor space A place for everything acts as a visual for material handlers Two wall tables, one rarely used Focus resources on one expanding jig Disorganized and dirty appearance Painted, resealed and cleared makes it obvious when something is out of order Then Now
