Firms have applied their e-business capabilities to management activities in order to raise the performance of business execution in a global market environment. In this e-business environment, the analysis and management for the performance of a firm’s e-business execution need to efficiently build and improve its e-business capability and competitiveness. This research presents the analysis framework for a firm e-business performance in order to efficiently manage and improve the e-business performance in this environment. The analysis items for a firm e-business performance are developed and extracted from the major components of a general firm performance in previous studies. The generated analysis items were verified by factor analysis and reliability analysis through a pilot test. The developed twelve items were extracted from first twenty items by these analyses. This study developed a 12-item tool that can totally analyze a firm e-business performance in an e-business management environment. The developed tool consists of four analysis factors and twelve items.
