To realize an autonomic system and method of improving the quality of a piece of software and solving problems with respect to operations in stages of a software life cycle. There are provided a pattern catalog 20 in which information on execution environments 11 to 14 in the stages of the software life cycle and information on patterns of design applicable in respective the stages of the software life cycle are stored, a pattern combination search engine 30 which searches the patterns with respect to each of the stages in the pattern catalog 20 on the basis of predetermined conditions including a design objective, and a pattern application agent 40 which applies some of the patterns found by searching performed by the pattern combination search engine 30 and controls the operation in the execution environments 11 to 14. Patterns which accord with the design objective are automatically selected to autonomically improve the quality of the piece of software. If a problem is found, an application of patterns obtained by searching performed by the pattern combination search engine 30 is again tried to autonomically solve the problem.
