Payback Period: 0.4 months (12 days)
Even with highest implementation costs, ROI is exceptional

Note: This example shows typical downtime costs at manufacturing facilities. Implementation costs vary significantly between open-source and proprietary
solutions—research specific options and calculate your own TCO.

Conservative vs Aggressive Estimates

Conservative Scenario (Use for Executive Approval)

Assume:

30% downtime reduction (vs 50% typical)
20% maintenance savings (vs 30% typical)
30% quality improvement (vs 50% typical)
10% energy savings (vs 15% typical)
Higher implementation costs (top of range)

Even conservative estimates typically show 6-18 month payback.

Aggressive Scenario (Stretch Goals)

Assume:

60% downtime reduction
40% maintenance savings
60% quality improvement
20% energy savings
Lower implementation costs (bottom of range)

Aggressive scenarios show 1-3 month payback and >2,000% 5-year ROI.

Recommendation: Use conservative estimates for budgeting, track actual results, and be pleasantly surprised.
