Rules (4)
rule
Rule: three thresholds before claiming an information edge — volume to clear noise, clean data, an actual decision someone will act on (and timeliness before commoditisation)
rule
R4 — Budget 20-30% of build effort annually for maintenance from day one; assign a metric-definitions owner; audit quarterly and archive any dashboard unopened in 30+ days
rule
R5 — Budget for pipeline maintenance from day one; if the client can't commit to upkeep, rent the managed version instead of building one
rule
R4 — Commit to a documented input-refresh schedule before shipping any customer-facing calculator; if you won't, don't ship it

Clubcard data-quality lesson — multiple users on one card produced false positives in mining (the "garbage in" warning from the best-documented winner)

Dashboard rot: data sources change schemas, metric definitions drift across departments, organizational attention wanes; custom/embedded builds carry the heaviest ~20-30%/yr maintenance burden
reference
Custom-embedded 3-year TCO converges on $300K-$630K (multiple, mostly vendor sources) with 20-30% annual maintenance; hidden costs are multi-tenancy/RLS, performance at scale, perpetual maintenance
reference
Refresh cadence: real-time matters for operational exception use (logistics ETAs, manufacturing downtime); daily suits most SMB KPIs; refresh frequency drives cost (Power BI Pro 8/day vs Premium Per User 48/day)
