Our ambition

Unlocking the full potential of Lean Six Sigma
Our ambition is to develop professionals capable of unlocking the full potential of Lean Six Sigma and turning it into meaningful and lasting value.

Qualified LSSx.0 Trainers

Consistent quality also depends on the people delivering the training.
We select experienced professionals with strong practical backgrounds, then train and certify them according to our requirements before accrediting them as LSSx.0 Trainers.
Only accredited LSSx.0 Trainers are authorised to deliver our programmes, helping ensure consistent, high-quality delivery across countries and learning formats.

Pascal Grenouilleau Black Belt

Med utdanning innen termisk teknikk og maskinteknikk tilbrakte jeg 25 år i energibransjen – hovedsakelig olje og gass – i Frankrike og internasjonalt, før jeg gikk over til rådgivning og opplæring for fem år siden. Gjennom min karriere har jeg bistått mikrobedrifter, SMB-er og mellomstore selskaper innen et bredt spekter av sektorer, inkludert industri – som energi, luksusvarer, bilindustri og næringsmiddelforedling – samt tjenester innen helse- og omsorg, lobbyvirksomhet og forsikring. Som sertifisert Lean Six Sigma Black Belt bidrar jeg nå med mer enn 30 års industriell og ledelsesmessig ekspertise for å hjelpe organisasjoner med å oppnå rask og bærekraftig fremgang.

Fra Lean Management til Six Sigma Black Belt er hvert program vi tilbyr bygget rundt en strukturert tilnærming til kontinuerlig forbedring. Deltakerne får praktiske verktøy, en grundig metodikk og et resultatorientert tankesett. Våre kurs kombinerer reelle casestudier, praktiske øvelser og aktive læringsmetoder for å forankre ferdigheter gjennom praktisk bruk, og gjøre hver deltaker i stand til å bli en nøkkelbidragsyter til transformasjon.

Det som driver meg i dag, er muligheten til å dele disse utprøvde problemløsningsmetodene, beriket med praktiske eksempler fra reell erfaring. Målet mitt er å gi deg verktøyene du trenger for å snu utfordringer til muligheter og lede prosjektene dine med effektivitet, grundighet og gjennomslagskraft.

Simon Tarea Black Belt

Som sertifisert Lean Six Sigma Black Belt-trener og -coach har jeg jobbet mer enn ti år innen rådgivning, inkludert fem år med utrulling av Lean i forsyningskjeder for tjenester i legemiddelindustrien. Siden 2020 har jeg fokusert utelukkende på opplæring og coaching, med én klar prioritet: å sette mennesket i sentrum for prestasjonen.

Jeg har en mastergrad i biomedisinske vitenskaper fra UCL, en mastergrad i ledelse fra IAG–UCL, og en profesjonell coachingsertifisering fra BAO. Jeg har lært opp mer enn 1,000 personer og coachet over 100 ledere, toppledere og entreprenører. Min tilnærming kombinerer engasjerende pedagogiske metoder med praktiske verktøy, forankret i troen på at varig transformasjon kun kan oppnås gjennom ekte individuelt engasjement.

Med en brennende interesse for læring ble jeg også sølvvinner i det franske mesterskapet i Mind Mapping i 2019, og jeg spesialiserer meg på produktivitet, konsentrasjon og effektiv læring. Disse ferdighetene gjør meg i stand til å hjelpe kravstore, høysensitive og multipotensielle individer med å oppnå klarhet, effektivitet og energi, samtidig som de kombinerer yrkesmessig prestasjon med personlig balanse.
