The Process of Customer Engagement: A Conceptual Framework
Abstract
Traditional measures of customer satisfaction have been criticized for failing to capture the depth of customer responses to service performance. This study seeks to redirect satisfaction research toward an approach that encompasses an understanding of the role of commitment, involvement, and trust in the creation of engaged and loyal customers. A conceptual framework for segmenting customer-brand relationships based on the extent to which customers are either new or repeat purchase customers of a specific service brand is proposed. The approach provides a deeper and more complete understanding of the nature of customer-brand relationships and the processes by which engagement may be developed and fostered among differing customer segments.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
