To date, research exploring interpersonal technology-mediated interruptions has focused on understanding how knowledge of an "interruptee's-local-context" can be utilized to reduce unwanted intrusions. However, the value of everyday interruptions are strongly tied to interrupter-interruptee relationships, interrupter's context and interruption content that we refer to as the 'relational context'. This suggests that a fresh approach to interruptibility research is needed that focuses on understanding how the knowledge of this relational context can be used to improve interruption management decisions. To address this concern a theoretical framework and associated research program are presented. The validity of fundamental aspects of this framework is then demonstrated through a study of cell phone call handling decisions. It shows that "who" is calling is used most of the time (87.4%) by individuals to make call handling decisions (N=834) unlike the interruptee's current local social (34.9%) or cognitive (43%) contexts. In addition, a clear disconnect was shown between the influence of local interrupee-context and relational context in terms of call handling decisions, suggesting that interruption management systems that focus only on an interruptee's-local-context will be ineffective. An alternative design approach is described to address these short comings.
