In practice, both maintenance engineers on site and maintenance managers should have a clear idea of how the maintenance plans are being carried out, and they will be improved continuously in the future. In this paper, the House of Maintenance Management (HOMM) is proposed to describe that what should be included in, for maintenance management. With HOMM, a continuous improvement process PDSA (Plan, Do, Study, Act) for maintenance management could be implemented. Focusing on mining industry, the details for mapping HOMM are discussed for the roof, ceiling, walls, floor, doors & windows, separately. Additionally, how to support decision making with this HOMM map has been demonstrated with a case study.
