What is PEXA
Eliminates the ambiguity and discontinuity between upstream and downstream artifacts, which had been the problem for conventional methods of analysis, design and implementation.

Provides a method of derivation and validation of artifacts, deliverable consistently from upstream to downstream.
- Sort out the artifacts based on predetermined abstract classification (stereotypes)
- Artifacts are verifiable both by customers and SEs
- Artifacts are managed by list (catalog), and all projects are manageable by the same configuration
- Due to clear relationship between the artifacts, the impact of design changes can be automatically extracted
- Tools to monitor artifacts and to support the creation of cross-reference lists
- Independent from specific industries or types of business
- Independent from specific development environment (OS, programming language, etc.)
- Applicable to projects that do not assume the application of the PEXA Engine
