The chapter defines the menu of tactics for policy advocacy, drawing upon practitioner literature and policy studies theory. The empirical basis for the book is presented, including a survey of 811 nonprofit organizations and 31 case studies that included interviews employing Q-methodology. Q-methodology is a research method to systematically and quantitatively analyze viewpoints on subjective topics, employing factor analysis to identify underlying structures of viewpoints collected from structured surveys. A set of six factors best fit the underlying data, explaining the greatest amount of variation among the nonprofits. A survey conducted with a representative sample of US nonprofit organizations found support for use of these tactics and strategies. Each strategy includes multiple tactics of advocacy activities, as well as short-term and long-term outcomes that the policy advocacy organizations associated with the strategy are seeking. The strengths and limitations of the research approach are briefly summarized.
