SCOH: AM Definition 2006 In order to fulfill its mission, the member departments need a common definition for asset management. What follows are the current definitions of asset management. It is motioned to combine these meanings into a single definition for use by the entire transportation community and to replace any previous descriptions. AASHTO s Asset Management Guide definition: A strategic approach to managing transportation infrastructure FHWA, Office of Asset Management definition: Am is a systematic process Highways Subcommittee on Maintenance Definition (July 2005). AM is a strategic and systematic process Motion New Definition to Supersede Previous Descriptions Transportation Asset Management is a strategic and systematic process of operating, maintaining, upgrading, and expanding physical assets effectively throughout their lifecycle. It focuses on business and engineering practices for resource allocation and utilization, with the objective of better decision making based upon quality information and well defined objectives. 8/7/2009 AASHTO SCOM/TRB MMS 2009 9

Maintenance Activities & Data
MM CHARACTERISTICS Definition CATEGORY MM CHARACTERISTICS Tactical activity to create day-to-day work orders What is managed? Materials, people, equipment, budgets, work orders When? What it does? Daily, weekly, monthly yearly operation Assign activities, track goods and materials, create work orders, etc. Who does it? How? Key focus: typically, Districts in a DOT, or local road agencies Budgets historically set by Chief Engineers decision and/or the annual budget food fight 8/7/2009 AASHTO TRB MMS SCOM/TRB 2009 AgileAssets MMS 2009 Inc. 13
MM Process Phase Activities 1 Asset Valuation Not typically expressly done 2 Performance Goals & Measures 3 Condition & Performance Assessment Largely Engineering focused. Equipment, resources, efficiency. Some Safety Inspection based 4 Alternative Analysis Undertaken on a qualitative basis; B/C used for Fed; May manually generate alternatives 5 Trade-off Analysis Performed by executive on a program basis from knowledge and experience 6 Program & Budget Review Management annual budgets, thru to, monthly monitoring programs, etc 7 Monitoring & Feedback Appropriate data access levels across programs; continuous improvement 8/7/2009 AASHTO TRB MMS SCOM/TRB 2009 AgileAssets MMS 2009 Inc. 14
