No IE time studies / Standard Minute Values (SMVs): Without SMVs, line balancing is guesswork and the 85% target is aspirational, not engineered.
No hourly output boards (§6.4): Supervisors detect underperformance at end-of-day. By then, the shift is lost. The control cycle is 8 hours instead of 1 hour.
Skill mismatch at bottleneck stations: Operators assigned to machine types where they are slower create fixed bottlenecks that no amount of overtime can resolve.
Structural transition gap (§4.2): The facility was designed for batch production but now operates as line-based. Line efficiency disciplines (Takt time, continuous flow) were never installed during the transition.
Governance barrier (§5.2): IE time studies are perceived as requiring MD-level approval. They don't — they are the Finance Executive's existing role (§1.2).
