Abstract: A method includes the steps of diagnosing existing conditions of long-term capital assets, equipment or fixtures, providing a performance warranty on the long-term capital assets, etc. The performance warranty is negotiated and signed prior to on-site inspection so as to transfer from owner to a provider the risk of maintaining performance of the long-term capital assets, etc. during a performance warranty term and within a standard or performance. Optionally, the performance warranty includes a condition warranty which guarantees conditions of the long-term capital assets, equipment or fixtures by component at the end of the performance maintenance warranty so as to guarantee the long-term capital assets, equipment or fixtures will operate for another extended period after the performance warranty, without performing by the provider any further maintenance thenafter.
