The document introduces the services marketing triangle, which consists of internal marketing, interactive marketing, and external marketing. Internal marketing involves training and communication with employees to enable them to deliver the promised service. Interactive marketing refers to the direct interaction between employees and customers. External marketing is aimed at end-users, and involves pricing, promotion, and communication to attract customers and set expectations. The triangle framework can be used to assess a service organization's performance across these three areas and identify strengths and weaknesses.
