Our method · SSI
Strategy breaks in the gaps between belief, design and people
Strategic Synergy Integration is the method behind every practice. It asks leaders and staff the same questions across nine areas, reads where their answers differ rather than averaging them, and names the one gap where the organisation is furthest apart. That gap anchors the work that follows.
How SSI worksIllustration: the named gap differs for every organisation.
