This chapter explores how the concept of social value evolved and the communication and practical challenges arising from new partnerships. It discusses the distinct steps that corporate partnerships tend to go through. Critical 'Fit to Partner' tests will be discussed. The reasons for alliances failing will be explored and a new partnership classification will be provided. Austin identifies distinct phases for partnership collaboration. The proliferation of partnership means there is an increasingly important role for intermediaries to help bring together corporates and non-governmental organizations (NGOs). Many partnerships are for a fixed length of time, typically 3–5 years, with a mid-term review. In working through the core criteria for a partnership there is the need for patience, diligence and enthusiasm. NGOs and corporates should first identify why the partnership is needed and whether mutual understanding can be established and sustained. Both parties need to explore and respect each other's vision and values.
