An Asset Portfolio is a collection of assets.  Asset Management. is the organizational capability that manages the lifecycle of the portfolio including: strategy, planning, organizing, acquiring,maintaining, upgrading, and divesting.  There are three principal asset management capabilities:

Human Capital Asset Management (HCAM^®),
Technology Capital Asset Management (TCAM™)
Physical Capital Asset  Management (PCAM™). 

All assets in the enterprise are either in the business of creating Throughput or creating Assets.  Therefore, there is no “overhead.”  Assets derive their value from the organizational capability for which they were acquired.  Therefore, the investment in assets has a value — and therefore a ROI.

Although this approach addresses the performance of all tangible and intangible organizational assets, human capital is the most misunderstood and “under-worked” asset — creating significant opportunities for productivity improvement in most organizations, industries, and countries.

HCAM^® is the management system that produces the right human capital to do the work required to execute the capability.  This is a fully integrated approach to the performance management, rewards, culture, and leadership designed to optimize the ROI in human capital.  This paradigm clarifies how to make investments in human capital that generate value in business terms.  See IHRIM Journal article, “Managing Human Capital as a Real Business Asset”.

Core Asset Management Systems:

HCAM^®  --  Human Capital Asset Management
PCAM™ -- Physical Capital Asset Management
TCAM™ -- Technology Capital Asset Management

Definition of Core Assets:

• Human Capital: The human capital of an organization is not people.  People own their human capital and invest it in many different areas of their lives: family, community interests, hobbies or sports, and work.  Therefore, a company's human capital asset, is the sum of talent, energy, knowledge and enthusiasm that people invest in their work. 
• Physical Capital:  The tangible things that we need to do our work that includes expenses such as plant and equipment, facilities, desks, chairs, phones, and computers, etc.
• Technology Capital:  Product and process technology (both intangible and tangible assets) - where as product technology includes patent formulas, product designs, etc; Process technology includes the "methods that delineate the steps in the process".
