How much is your data team's friction actually costing you?
Most of what you pay your data team is invisibly paid again by the rest of the business: hours lost to broken or misfit data products. That cost is FTE Debt — hours lost to workarounds × fully-loaded hourly cost — and it's the largest invisible line item on most data portfolios.

How do you give your CFO a portfolio view of data spend?
Your CFO can audit any other portfolio in financial terms; data has been the exception. Impact Operations is the capital allocation system that fixes that — three metrics (FTE Debt, PCU-V, CDSI) give CEOs and CFOs a portfolio-level financial view of where data investment is returning value.

Why is my data team always busy but nothing improves?
When your data team is always busy but the roadmap isn't moving, most of their capacity is going to unplanned work that's invisible to leadership. CDSI (Capacity Drain & Shift Index) scores this drain on a 1–12 scale: healthy 4.2–7.2, fragile above 7.2, locked above 9.5.

What is the real monthly cost of a data product?
Most data budgets only capture infrastructure cost. The real monthly cost of a data product, once you add incidents, support, and change requests, is typically 2-4× that. PCU-V (Portfolio Capacity Units, Verified) measures the true carrying cost and gives your portfolio a capacity ceiling you can defend.

How do I measure data team ROI?
Measure three things: the cost the business pays for data friction (FTE Debt), the true monthly carrying cost of each data product (PCU-V), and where team capacity actually went (CDSI). The ratio of FTE Debt displaced to PCU-V is a Portfolio ROI Ratio a CFO can evaluate.

Why is my data team always busy but nothing improves?
Because most of their capacity is going to invisible unplanned work, incidents, ad-hoc requests, support, that never appears in the sprint plan. CDSI measures the gap between what leadership sees and where the hours actually go.

How do I explain data ROI to my board?
Translate engineering metrics into capital allocation language. Boards respond to Portfolio ROI Ratio (FTE Debt displaced ÷ PCU-V), not story points or dashboard counts. Frame the data function as a portfolio of assets the CFO can evaluate.

Should I reduce my data team size?
Possibly, but not before you measure what each product costs to sustain (PCU-V) and what the business loses if it disappears (FTE Debt). Cutting headcount without a portfolio view usually moves the work to the business rather than eliminating it.
