Capture Demand for New Projects

Why

Pipeline items — new products, migrations, scaling events — represent 20–50% of next-quarter spend changes. Without standardised capture, forecasts are blind trend-line extrapolations and Finance loses trust in cloud economics. A $200K unexpected service launch discovered only in quarterly reviews is a planning failure, not a cost failure.

What

Establish a quarterly demand intake process with a standardised template that captures cost estimates for new cloud initiatives. The output is an aggregated planning summary that feeds into forecasting and budgeting.

How

Create the Demand Intake Template

Use a shared spreadsheet, Confluence page, or ServiceNow catalogue item. The format matters less than doing it consistently every cycle. Required fields:

FieldExampleWhy It Matters
Initiative NamePayment Service v2 MigrationLinks to business value
OwnerJane Smith (Eng Lead)Ensures follow-up on estimate changes
Target Go-LiveQ2 2026Times the impact for budgeting
Cloud Provider(s)AWSSelects the right estimation tools
Key ServicesEKS, RDS PostgreSQL, S3, ALBPinpoints cost drivers
Expected Scale50K TPS peak, 2TB storage/moCore input — underestimating doubles bills
DurationPermanent (production)Affects commitment decisions (Spot vs RI)
Estimated Monthly Cost$18,000–$22,000Use ranges, not single numbers
Confidence LevelMedium [architecture not final]Guides buffer size in forecasting

Use cloud-native pricing calculators (AWS Pricing Calculator, Azure Pricing Calculator, GCP Pricing Calculator) for estimates. You don’t need perfect numbers — a range with a stated confidence level is infinitely more useful than no estimate.

Define Governance Roles

Product / Eng LeadsProvide initiative details, own estimate accuracyQuarterly intake, monthly refresh
FinOps PractitionerFacilitate intake, validate estimates, aggregatePer intake cycle
Finance ApproverReview aggregated plan vs budget, flag risksEnd of quarterly planning
Executive SponsorEnforce participation, resolve disputesQuarterly kickoffs

Run the Quarterly Intake

Collect demand signals from all business units. Aggregate into a planning summary:

This becomes the INPUT to Forecasting.
