The Hidden Cost Pattern
The Consequence
Business units consume services without cost visibility. Zero incentive to optimize. Shadow infrastructure proliferation.
Example: A department buys a departmental email solution for $8/user/month because they don't know corporate email 'costs' $50/user/month.
The Solution
Showback model makes IT costs visible. Chargeback model makes them financially real.
Cost made visible
20% reduction in unnecessary shadow services within 12 months. Visibility alone changes some behavior.
Cost made real
30–40% reduction plus genuine behavior change. Business units optimize because their own budget is on the line.
Organizations that show IT service costs: 20% reduction in unnecessary shadow services within 12 months. Organizations that charge back: 30–40% reduction plus behavior change.
The Resistance
Business units will complain they're being 'charged for overhead.' Reframe: They're not being charged for overhead. Overhead costs existed before; now they can see what they are and choose to optimize.
“We made IT costs visible through showback. Business units immediately asked why their email costs were different. That question-asking drove optimization we never could have imposed.”
