This chapter describes a methodology for investigating lived experience, and explains the underlying philosophy and procedures for generating, analysing and interpreting data. I used this methodology to research psychosocial factors affecting enactment of pro-environmental values by sustainability managers. I situated the research subjects in the dynamics of their work settings and the socio-cultural context in which they and their organisations are embedded. The methodology is transdisciplinary, integrating Interpretative Phenomenological Analysis with frame and metaphor analysis, and draws upon systems thinking concepts as well as theories of psychological threat and coping, needs, emotion and embodied cognition. The methodology enabled me to identify and model multiple cross-level factors. An example of analytic commentary is included, demonstrating the nuanced in-depth insights that can be generated with this approach.
