The aim of this paper is to reflect on the evaluation of DELTA, a distributed learning resources repository. We employed scenarios and claims analysis techniques so as to derive assessable evaluation goals. These goals were related to three quality dimensions: quality of use, pedagogical effectiveness and acceptability for the end-users. We employed a set of six quantitative and qualitative research methods and triangulated the results obtained. The results demonstrate that DELTA met around half of the evaluation goals. This project was an opportunity to reflect on the degree of fitness for purpose of our methods. Two of the qualitative methods employed (user diaries and pedagogy workshop) were particularly effective in the triangulation process.
