The investigation of singular practices and actions is the bedrock of Conversation Analysis (CA), yet it is not the only approach that CA research can take. This chapter poses a series of analytic questions designed to guide the analyst’s attention towards a complementary mode of analysis, one which takes as its object of study not a singular practice but rather a system of practices, alternative solutions to a recurrent problem of social organization. While this approach has been employed to greatest effect in research on generic organizations of interaction, the analytic techniques are themselves generic and applicable across domains of action. Rather than select a practice or action and ask what forms it can take or what environments it can inhabit, conversation analysts can instead select a problem, an exigency of social interaction, and ask how participants solve it. Alternative practices and actions naturally cluster around the organizational problems to which they serve as possible solutions, and it is this endogenous organization that CA research aims to document. The chapter sketches out and illustrates a range of analytic techniques that conversation analysts have employed in past research and can employ again to discover and investigate organizations of practice.

While the preceding chapters of the Handbook have focused on practical skills in CA research methods, this chapter looks towards the path ahead. A diverse group of conversation analysts were asked to outline possible projects, point readers toward un- or under-described interactional phenomena, and discuss persistent issues in the field. The contributions address future advances in data collection, specific interactional practices, the complex interplay between language and the body, and cross-cultural and crosslinguistic comparisons, among other issues. The chapter concludes with a concise reiteration of the bedrock principle that underpins all CA research methods.

This chapter provides an overview of foundational principles that guide CA research, offered both on the basis of our own experiences as researchers, and from our discussions with other conversation analysts as they authored contributions for the present volume. We begin by briefly sketching of some of the fundamentals of human social interaction, in order to underscore CA’s central focus, the study of social action, and describe some of the basic features of how interaction is procedurally organized. These basic features of interaction, which CA research has rigorously evidenced and which guide our examination of new data, are then shown directly to inform CA as a research methodology. Put another way, it is precisely due to the procedural infrastructure of action in interaction that conversation analysts use and work with interactional data in particular ways. We conclude with advice for readers as they continue to explore the volume’s contents.
