Attendance may be for private purposes, which is not associated with an organization, such as keeping a personal travel log, or it is for business needs, which is part of organizational attendance and sometimes associated with multiple organizations. Therefore, the recording, sharing, and analysis of attendance data require elaborate management. The HAO attendance system is a lightweight and mobile attendance platform. It takes the user and organization as two starting points and is driven by HAO intelligence consisting of human intelligence (HI), artificial intelligence (AI), and organizational intelligence (OI). This study builds the knowledge graph of the HAO attendance system and puts forward the closed-loop authority management structure of the HAO attendance system, supplemented by the privacy authority management method from coarse-gained to fine-gained level to ensure refined attendance management and protect the users’ privacy, thereby promoting the intelligent transformation of a new-generation attendance system. For organizational attendance analysis, a four-element scoring method and a four-element attendance reporting method are designed to calculate employee attendance scores, generate accurate and comprehensive attendance reports, provide decision-making support for organizations, and inspire the vitality of both organizations and individuals, so as to build intelligent organizations with organizational intelligence.
