Higher education institutions (HEIs) need to understand their alumni when drawing strategic relationship programmes. This paper aims to identify clusters of alumni based on their commitment relationship and to analyse factors influencing their intention to collaborate with the HEI. The study took place at a Portuguese university, considering a dataset of 1075 of alumni asserting intention to collaborate. First, a cluster analysis was conducted to identify patterns of commitment relationship. Secondly, a logistic regression was run to identify determinants of intention to collaborate. Both techniques revealed the decisive role of HEI commitment in the process. Relationship advantages and positive feelings towards the HEI were also pointed out as important. Alumni asserted recommendations, further training, sharing experiences and giving help as ways to collaborate with HEI. Regression results suggest that sociodemographic variables such as gender, marital status and volunteering are significantly associated with a probability to collaborate. Results also show that affiliation in sororities/fraternities and participation in extracurricular activities are significantly associated with that collaborative intention. The findings provide clues to support strategic relationship programmes based on consistent marketing campaigns, while bringing value to the literature in the European context, where alumni culture requires real insights to evolve.

高等教育机构（HEI）在制定战略关系计划时需要了解其校友。本文旨在根据其承诺关系来确定校友群体，并分析影响其与HEI合作意图的因素。该研究在葡萄牙一所大学进行，考虑了1075名声称有合作意向的校友的数据集。首先，进行了聚类分析以识别承诺关系的模式。其次，进行逻辑回归分析以确定合作意向的决定因素。两种技术都揭示了HEI承诺在此过程中的决定性作用。人们还指出，人际关系优势和对HEI的积极感受也很重要。校友提出建议，进一步培训，分享经验和给予帮助，作为与HEI合作的方式。回归结果表明，社会人口统计学变量（例如性别，婚姻状况和志愿服务）与合作的可能性显着相关。结果还表明，社团/兄弟会的归属和参加课外活动与该合作意向显着相关。这些发现为在持续的市场营销活动基础上支持战略关系计划提供了线索，同时在欧洲背景下为校友文化带来价值，在欧洲背景下，校友文化需要真正的见识才能发展。结果还表明，社团/兄弟会的归属和参加课外活动与该合作意向显着相关。这些发现为在持续的市场营销活动基础上支持战略关系计划提供了线索，同时在欧洲背景下为校友文化带来价值，在欧洲背景下，校友文化需要真正的见识才能发展。结果还表明，社团/兄弟会的归属和参加课外活动与该合作意向显着相关。这些发现为在持续的市场营销活动基础上支持战略关系计划提供了线索，同时在欧洲背景下为校友文化带来价值，在欧洲背景下，校友文化需要真正的见识才能发展。
