An often overlooked aspect of service delivery in business‐to‐business settings is the issue of service quality among internal organizational units. Yet, in practice many organizational departments are service providers primarily to customers within the organization. For example, management information systems, human resources, and purchasing departments all share an important function supporting other employees as they perform their jobs. Managers of those internal service functions are becoming more concerned with delivering high levels of service quality to their internal customers. This article explores the dimensionality of customer service quality as perceived by a set of internal customers of an organizational buying unit, and examines the potential for segmentation of internal customers. Managerial implications and recommendations are presented to aid organizations desiring to improve internal service quality.

Improving glycemic control across a primary care diabetes population is challenging. This article describes the development, implementation, and outcomes of the Diabetes Care Collaborative Model (DCCM), a collaborative team care process focused on promoting effective insulin use targeting patients with hyperglycemia in a patient-centered medical home model. After a pilot, the DCCM was implemented in 18 primary care practices affiliated with an academic medical center. Its implementation was associated with improvements in glycemic control and increase in insulin prescription longitudinally and across the entire population, with a >1% reduction in the proportion of glycated hemoglobin >9% at 2 years after the implementation compared with the 2 years prior ( P < .001). Facilitating factors included diverse stakeholder engagement, institutional alignment of priorities, awarding various types of credits for participation and implementation to providers, and a strong theoretical foundation using the principles of the collaborative care model.
