AI-Ready Operations
The operator layer for putting AI agents into production - readiness, use-case selection, an AI governance register, an agents-in-production tracker, an AI CoE handbook and AI vendor TCO. Govern the agent, don't just buy it.
Why this is operator-grade
Built by Petko Petkov - a 15-year enterprise IT operator who has sat on both the vendor-distribution and buyer-operator sides of the table. Every Vihren Labs product is built from real scenarios: real SAP T-codes, real regulation article numbers, real cutover-night failure modes. Not consultant theory - the templates the operator wished existed when the system had to work on Monday morning.
About the makerThe thinking behind it
Your AI agent will amplify your data problems, not fix them
An AI agent is an amplifier - point it at fragmented, duplicated, or stale data and it scales the confusion, fluently. Why bad data no longer looks broken but looks persuasive, why enterprise systems were never built for autonomous decisions, and the three readiness questions - identity, completeness, source of truth - to answer before you deploy an AI agent on anything that matters.
Governance, not agents: the operating model most AI programs skip
Most AI agent projects don't fail on the model - they fail on the operating model: no decision rights, no use-case gate, broken data, runaway cost, no owner after launch. Why the first question isn't 'which agent should we buy' but 'who owns this, and how do we decide', and what an AI Center of Excellence actually is - a thin function with a charter, a GO / PILOT / PARK gate, eval standards, a risk register, and run-and-maintain ownership across the agent lifecycle.
