Last updated 2026-06-07 - Playbook expanded to a 15-page operating handbook - a readiness self-check, the "past the point of deferral?" estate diagnostic, the five options each with its trap, the brownfield/greenfield/selective asset-vs-liability test, the business case both sides with the cost-of-not-acting frame + a worked 5-year TCO + the data-remediation line, the weighted scorecard with a worked result, the RISE/commercial deep-dive, the one-page board decision, data-first phasing + the dual-running trap, choosing the SI, the seven failure modes as a symptom-to-fix catalogue, the people side, the first 90 days, objections, and a worked example throughout (Meridian, a €400M manufacturer on ECC) - plus templates + a glossary.

Transformation & SSC/GBS

Offshoring, GBS rollouts, and BPO transitions - from kickoff to BAU exit, plus the pre-implementation decisions that come before them. A full operator course and seven standalone toolkits - transition delivery, process automation, org change, PMO, target operating model, cloud migration and the ERP modernisation business case.

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.
