Although the results obtained ment of that particular airport APM system. for that one particular airport cannot be assumed to be universally applicable, there is again industry experience that 3.3.1 Measurement Factor: Cost indicates such results can at least be deemed typical. Thus, an abbreviated version of that approach is presented in this As previously stated, cost, or more specifically, the quest chapter without any specifics applicable to that airport. for the lowest cost, is the apparent primary reason for airport The intent is to offer a general outline of an analysis that can authorities recently departing from the historic contractual be usefully adapted and emulated by other airports in their model of sole sourcing ongoing O&M services. Thus, in com- quest to objectively evaluate procurement methodologies for paring the four contractual procurement options, cost is an ongoing O&M services. important measurement factor.
