We use adoption and usage data on the client, and firm-client interactions across 4 technology generations of new-age products/services from 13 developed and emerging markets over an 8-year period to describe how the multigenerational services ( MGS) adoption behavior influences direct (purchases) and indirect (references and feedback) global client engagement, and how this relationship is moderated by product/service failures and cultural factors. We propose metrics to measure the number of generations adopted ( MGD), the number of products and features within a generation ( MGF) and the adoption time between generations ( MGT). We find that client usage revenue ( CUR) is enhanced by higher multigenerational depth and features combined with lower adoption timing. However, CUR varies due to differences in the needs of the client’s own customers, failures, and culture. A higher direct engagement affects the reference and feedback behavior that is moderated by cultural differences in individualism, power distance and masculinism. For a typical client in the US and Canada, a one-unit improvement in MGD and MGF, and a one-year improvement in MGT enhances client usage revenue by $8.15K, $5.20K, and $2.31K per client, respectively, versus a corresponding enhancement of $4.82K, $3.64K, and $1.62K, respectively per client for Columbia and Mexico. We provide several implications for executives who manage multigenerational innovations across countries regarding client engagement, launching MGS, market-entry, and failure recovery.
