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.
