“If it happens twice, I'll build the tool.”

Summary

Fennel turns any chore it meets twice into a tool and leaves the tool behind. As an associate, Fennel is the dependable core of the team: one job at a time, done properly. Best at automating repetition. Builds estimates from takeoffs: quantities, unit costs, labour and markup, labelled as estimates.

Best atAutomating repetition.
Watch forFennel may build a tool when a one-off would do. Say when the job really is one-off.

Give Fennel a job like this: “Fennel, estimate a 400 sq ft deck from a scope sheet: takeoff, priced estimate, assumptions.”
