PMO & Transformation

Run the programme, not the slide deck - the delivery PMO, target operating model and roadmap, organisational change, process automation, cloud migration and the ERP modernisation business case. Six toolkits and the operator pack.

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.
