The present invention provides a processing procedure management device which can determine a process procedure by adapting to a performance change of a function engine used for information processing at a high speed.The present invention includes a procedure database 31 which stores a processing procedure and its performance information, a performance history database 32 which stores a performance observed when information processing is carried out according to a processing procedure and a performance observed for each function engine which carries out a processing module that constitutes a processing procedure, a performance observation unit 33 which acquires the observed performance hereof, a future performance calculation unit 34 that calculates a performance at some point in the future for each function engine, a procedure generation unit 35 which reconstructs a processing module based on a performance in the future and generates a new processing procedure, a procedure updating unit 36 which adds a generated processing procedure and its performance information to the procedure database 31, and the procedure solving unit 37 that determines a processing procedure for carrying out designated information processing from the procedure database 31.
