Autonomic computing (AC) is a new domain, based on AC theory to design autonomic system is not perfect and implement process is more difficult. Especially, there lack tools and models to test the autonomic system. According to above-mentioned reason, this paper mainly discusses dependability of autonomic software. We proposed a model to analyze autonomic maturity of software: First introduces software autonomic characteristics, autonomic manager; Second, summarizes the software complexity, relation between the autonomic and the complex; Third discusses problems of software autonomic and resolve technology. Finally analyses validness of the model. In the future, it is to be optimized in the application.
