For the Marine Stewardship Council (MSC), we undertook a comprehensive review of governance. The MSC Board realised, when it was roughly four years old, that its initial governance structures were unwieldy, insufficiently open and not transparent enough to facilitate the MSC's rapid growth. The MSC established an international governance review panel and selected Z/Yen to facilitate the review, so the review could be independent whilst overseen at board level. It was crucial that the multiple stakeholders in the MSC (funders, supporters, staff, food industry, environmental groups, scientists, certifiers and many other interested parties) were all able to participate in the review. The process included then innovative use of web-based questionnaires (over 50% of responses were web-based) for ease of use and speed of analysis. It also required an iterative approach; an initial survey was followed up with an outline of the possible new structure for comment and shaping. As well as facilitating the consultation, Z/Yen ensured that the review followed due process within the UK's charity law, provided governance models to underpin the consultation and ensured that the lawyers reflected the emerging ideas in the resulting legal drafts.
