This book offers a practical guide for policy advisors and their managers, grounded in the author’s extensive experience as a senior policy practitioner in New Zealand’s Westminster-style system of government. This second edition has been substantially revised and updated. It provides an expanded, step-by-step approach to stakeholder analysis and prioritisation in relation to an agency’s own strategic frame; it aligns and integrates theory about the public interest, public value and anticipatory governance; and it updates a “fair go” multi-criteria decision analysis matrix with the latest iteration of the N.Z. Treasury’s Living Standards Framework.
