Methodology and methods are only part of the story of choosing a research framework. The way you go about collecting and interpreting data is strongly influenced by how you interpret knowledge and truth. This is about the epistemology. In simple terms, epistemology is the theory of knowledge and deals with how knowledge is gathered and from which sources. In research terms your view of the world and of knowledge strongly influences your interpretation of data and therefore your philosophical standpoint should be made clear from the beginning.

When planning for a practice-based enquiry or small-scale study you will most often be confronted with the choice between an action research or case study approach. Here is a simplified exploration to get you started.
When preparing a practice-based enquiry or research you will need to ask yourself how you will answer your research question or test your hypothesis. The methodology and methods section of a proposal or write-up lays out these ground rules and approaches you take.
Pink's understanding of ethnography is broader than that of a study relating to the culture or society of humans. Really, ethnography in Pink's view is a phenomenological study of life world and in the book she offers ways of accessing this life world through a range of channels. Pink suggests including the human senses at all levels of research. This book offers great justification for a less conventional approach to research; an approach where openness to what happens is paramount.
