The project will use real-world data from clients of participating NPOs, who have agreed to collaborate. For the integrated DLV model, three types of data sources will be needed: First, we need longitudinal donation history data for individual donors, i.e., when and how much did donors contribute in the past. Second, we need marketing data from the NPOs, i.e., when did an NPO communicate with the donor, the communication channel (e.g., telephone, email), the content of the appeal, and related costs. Third, we need data on non-monetary elements, e.g., on donor referrals, or voluntary work. Data from all these three sources need to be merged.
Before estimating the data, it is necessary that data from different NPOs is first synchronized. Typically, NPOs have different data management systems, such that the data structure and labeling may vary substantially. Our first accomplishment has been to develop a common data frame for the model estimation to be feasible. The DLV model will be calculated based on existing CLV (Kumar 2018).
In order to assess the external validity of the developed DLV model, a field study will be conducted in collaboration with one of the NPOs. The validation study is a marketing campaign, and the purpose is to compare different targeting strategies with respect to donor response. The campaign will be provided to 1) a randomly selected donor group (no targeting); 2) a donor group selected based on DLV with monetary elements only, and 3) a donor group selected based on the integrated DLV model. Differences between these three groups will demonstrate the DLV impact on future donor response.
