Table IV

Research design aspects based on Gibbert et al. (2008)

Methodological aspect	Tactic	Description
Internal validity	Research framework derived from literature Pattern matching Theory triangulation	Analytical constructs employed draw on theoretical insights from the impact value chain model and the role of intermediaries in social value creation Using the analytical constructs, similarities within the groups and differences between the groups were identified (Eisenhardt, 1989)
Construct validity	Data triangulation Review of transcripts by key informants Chain of evidence Explanation of data analysis procedure	Combination of primary and extensive secondary data Secondary data collected was structured in a database, following the guiding questions Cross-checking of facts and information between interviewees, during the data collection Member checks conducted after the data collection to avoid misinterpretation or misunderstandings (Shenton, 2004)
External validity	Nested approach to cross case analysis Case study background Replication logic	One unit and four subunits of analysis All four projects are market-based initiatives (compare), but have different governance structures (contrast) Thick project description in the case file and detailed case background provided in the findings
Reliability	Case study protocol and database	The data collection was conducted according to a set of guiding questions following the analytical constructs and project-specific highlights Development of a case study database with all data sources
