1 Factory Building Symposium on Lean Production January 29, 2007 Austin, Texas

2 Four Seasons Housing, Inc. Middlebury, IN Austin Baidas, CEO and President Level the Load

3 Four Seasons Housing  Started:1994  Location:Middlebury, IN  Home type(s):Primarily HUD Code  Price point:Moderate  Design:Limited customization  Production:10 floors/day  Market area:Northern US

4 Objective: Balance the Line  Eliminate non-value added (NVA) activity  Reduce cycle time variability › Station to station › Floor to floor

5 Strategy 1.Map product flow 2.Analyze data to identify causes of cycle time variability 3.Implement solutions that reduce NVA and control cycle time variability

6 Sources of Variation  Double vs. single floor stations  Variation in complexity from A to B half Tactic: Convert single floor stations to double floor stations

10 Results  Reduced through-put time 27%  All production within facility  Eliminated NVA protection for outside floors  Eliminated NVA moves  Identified real-time data collection requirements  Started a kaizen project list

11 Highlights  Lean initiative driven by business objective  Established lean process  Identified root cause  Listened to the data  Workers contributed mightily

12 Lessons  Lean cannot be forced by one person  Involve employees  Allow team to own the decisions  Lean is a process

13 Going Forward  Refine our lean process  Conduct kaizen events to improve efficiency in departments  Revise plant layout to convert to double floor stations
