Follow one question through the records.
This is a simplified example of the method, not a client result and not a software demo.
01 / The question
Where did the job economics change?
Start with one completed flooring installation job and a practical question: why did it contribute less than expected?

02 / The records
Bring the relevant records together.
Quote, material, installation, other direct cost, and callback records converge around one job. Billing stays visible, but separate from the direct-cost calculation.

03 / Expected result
The quote set a $5,000 direct contribution.
The $12,000 revenue basis less $7,000 in quoted direct costs is the starting expectation—not a claim about net profit.

You should be able to see why.
Important results stay tied to the records and calculation behind them. Missing information stays missing. It is not quietly treated as zero.

Questions, not feature lists
Questions RBA helps investigate
The work starts with a business question whose answer is scattered across operating
records.
01Where did job costs outrun the quote?
02Are material increases reaching customer pricing?
03What completed work still needs billing review?
04Where did actual labor differ from the estimate?
05Which repeat jobs are becoming less economical?
Broader operating contexts
Close to the work. Grounded in the records.
01
Manufacturing & specialty builds
Quoted versus recorded job economics across material, labor, and other direct costs.
02
Equipment dealers & industrial distribution
Purchasing, pricing, service, parts, and billing relationships around the work.
03
Field service
What was sold compared with the time and direct costs required to deliver it.
04
Installation businesses
Quotes, approved scope, material, installation cost, callbacks, and billing.
