"Poor" Performers
A statement, that is qualitative and/or quantitative, on the results of a single asset or a single building when compared to others in the same class.

1.  In reference to an asset, an asset that achieves a service life that is less than the modal year on the probability distribution when compared to all other assets of the same class (equal life group).


2.  In reference to a building, the reinvestment funding requirements are higher than the average of all the buildings in the statistical population as a  result of factors such as less durable products, high exposure conditions and poor maintenance practices.



Attributes
Listed below are some of the attributes of "poor" performer asset scenarios:

Examples
Included below are some examples of "poor" performer scenarios relative to asset performance
  • The average 2-ply SBS roof achieves a service life of 25 years but our roof has lasted only 18 years. It is therefore a poor performer.
  • Our boiler failed at 10 years, which is 5 years before the average service life for that type of boiler.

Scenarios

Causes
Listed below are some of the reasons why an asset will exhibit poor performer characteristics:

Analysis
Understanding of high performers requires analysis relative to the following statistical concepts



Management Principles
Included below are some of the asset management principles to be considered in relation to high performer assets.
