Procurable products can be identified through trade shows, technology committees, transition teams, consultants, and manufacturers. Using whatever technical assistance is deemed appropriate, purchasing agents must evaluate the utility of the technology in terms of how it will work in a particular facility, how it will aid operations and what changes it will necessitate, and how well it will hold up under stress. In purchasing, requests for proposals allow the purchaser to evaluate thoroughly the system before issuing a contract and permit an analysis of quality as well as price. Prequalifying contractors may benefit the purchaser by assuring that the low bidder will be qualified and able to provide an acceptable end product. In addition, there must be compatibility between the product and its installation. Installation companies should be selected on their own merits in terms of such criteria as service response time, financial capability, and adequacy of the service organization. Complete product and performance specifications describe the purchase and are critical in settling disputes if purchaser expectations are not met. Finally, system tests should be conducted after installation, and contract should cover warranties, training, and maintenance. 2 photographers.
