Life-Cycle Software Design includes the whole developmentcycle:
Enterprise Architect provides complete traceability from requirements analysis and design artefacts, through to implementation and deployment. Combined with in-built task and resource allocation, Project managers and QA teams are equipped with the information they need to help deliver projects on schedule.

Effective Project Management
Project managers can use Enterprise Architect to:

•Assign resources to elements
•Measure risk and effort
•Estimate project size and complexity
•Implement change control and maintenance procedures
Enterprise Architect's Use Case Metrics capability makes it easy to assess relative project complexity, based on the number and type of use cases within the model, the type of project and capabilities of the development environment.

With experience, use case metrics provide a great way to quickly assess the scope of a project.

High Value, End-To-End Modeling
Enterprise Architect provides full life cycle modeling for:

Business and IT systems
Software and Systems Engineering
Real-time and embedded development

With built-in requirements management capabilities, Enterprise Architect helps you trace high-level specifications to analysis, design, implementation, test and maintenance models using UML, SysML, BPMN and other open standards. Enterprise Architect is a multi-user, graphical tool designed to help your teams build robust and maintainable systems. And using high quality, built-in reporting and documentation, you can deliver a truly shared vision easily and accurately!

Enterprise Architect
Sparx Systems are pleased to announce the release of Enterprise Architect 14.1, a major upgrade that redefines the modeling experience and introduces many exciting new tools and capabilities.
