03 — The JBKR Method
Every project — on any front — follows the same path: from problem to continuous operation, with scope and success metrics defined before any code is written
Discovery
1–2 weeksWe map the problem, the systems involved and the data available — starting from the free 30-minute assessment.
You get: Scope, success metrics and an honest estimate
Proof of concept
2–4 weeksWe build the smallest version that proves the value — one workflow, one integration, one chatbot over your real documents — before any large commitment.
You get: Working prototype with your real data
Production
scope-dependentWe evolve the proof of concept into production with security, tests and telemetry. Nothing ships without a measurable quality bar.
You get: System live, documented and monitored
Continuous operation
monthly plansOngoing support under the monthly plans: monitoring, data-driven improvements and fast response when something changes — including in your legacy systems.
You get: Continuous evolution with same-business-day response
