In this chapter, the authors focus on three challenges related to the attributes of the interactive business world and on the related implications for methodology. The first challenge is how to capture the continuity of business relationships, which implies: (1) Taking a two-sided (bilateral) view when researching business relationships, (2) collecting data on content and consequences of business relationships and (3) developing a research design to capture development over time. The second challenge is how to set boundaries and trace network-like structures, which implies: (1) identifying the relevant relationships that appear to affect each other in a network-like manner, (2) capturing interdependences among relationships (how they affect each other) and (3) researching forces generating network dynamics (how these interdependencies are established and change over time). The third challenge is how to observe and research interaction processes in business relationships, which leave little traces and are difficult to record. This requires the attention on (1) the choice of point(s) of observation, (2) the handling of the subjective understanding of interaction and (3) researching how interaction unfolds. The authors conclude with a discussion on the complexity of handling these challenges, and related methodological choices, when ‘research objects’ are interconnected.

The study here examines how business actors adapt to changes in networks by analyzing their perceptions or their network pictures. The study is exploratory or iterative in the sense that revisions occur to the research question, method, theory, and context as an integral part of the research process.

Changes within networks receive less research attention, although considerable research exists on explaining business network structures in different research traditions. This study analyzes changes in networks in terms of the industrial network approach. This approach sees networks as connected relationships between actors, where interdependent companies interact based on their sensemaking of their relevant network environment. The study develops a concept of network change as well as an operationalization for comparing perceptions of change, where the study introduces a template model of dottograms to systematically analyze differences in perceptions. The study then applies the model to analyze findings from a case study of Norwegian/Japanese seafood distribution, and the chapter provides a rich description of a complex system facing considerable pressure to change. In-depth personal interviews and cognitive mapping techniques are the main research tools applied, in addition to tracer studies and personal observation.

The dottogram method represents a valuable contribution to case study research as it enables systematic within-case and across-case analyses. A further theoretical contribution of the study is the suggestion that network change is about actors seeking to change their network position to gain access to resources. Thereby, the study also implies a close relationship between the concepts network position and the network change that has not been discussed within the network approach in great detail.

Another major contribution of the study is the analysis of the role that network pictures play in actors' efforts to change their network position. The study develops seven propositions in an attempt to describe the role of network pictures in network change. So far, the relevant literature discusses network pictures mainly as a theoretical concept. Finally, the chapter concludes with important implications for management practice.
