The Repertory Grid method is based on Alternative Constructivism, a psychological theory by G.A. Kelly. Kelly postulates that people evaluate situations with the help of subjective assessment factors. According to Kelly, these assessment factors determine our perceptions and influence our decisions heavily.
The Repertory Grid Methodology enables the researcher to elicitate and understand these assessment factors in a structured and scientific way. The repertory grid is a qualitative in depth interview. It combines an open approach to data collection with the possibility to analyse the data with statistics.
The computer-based repertory grid instrument e-VAL was developed jointly by GIZ and nextpractice. It was designed for the purpose of evaluating development cooperation interventions. Being an open and qualitative interview method, e-VAL allows to systematically collect opinions - thus complementing the measurement of quantitative indicators with other M&E instruments.
The results of an e-VAL application allow for a comparison of perspectives and assessments of the project team, partners, intermediaries, target group or other stakeholders. They assess the development cooperation intervention by formulating and applying their own criteria for success - what's "good" is not prescribed by a questionnaire but is the individual's choice.
