Key
Hypotheses as they are formed and concluded
through this research |
|
| 1. |
To re-define Lean requirements for
wood processing companies, specific components of lean production
must be identified and quantified. Then, quantitative models may be
developed and quantitified and encoded in an industry-specific Lean
Index (LI). -Done- |
| 2. |
LI can be modeled as a function of macro-level factors
and micro-level factors. For validation of individual models, correlations
must be established to test the equivalency of LI(macro) to LI (micro).
-Done- |
| 3. |
Lean may be modeled based on the lag times of material
moves through the process. |
| 4. |
Primary wood processing is leaner than secondary
wood processing. -True- |
5. |
Lumber drying is the least lean operation in the
hardwood industry. -True- |
6. |
"Leaner" does not necessarily mean lower
cost. |
7. |
"Leaner" does not necessarily mean lower
inventory. -True- |
8. |
"Leaner" operations exhibit higher throughput. |
| 9. |
A supply chain of integrated sub-contractors is
leaner overall than a single vertically integrated company. |
| 10. |
Energy usage is a critical component of "leanness"
in wood products operations. -True- |
| 11. |
Pull production results in leaner operation than
push production for a given facility. |
