Avolution Abacus is a highly flexible tool for enterprise architecture modelling and for analysing the models using pre-defined metrics.
The main features of Abacus that gives it a competitive advantage includes:

A meta-meta-model that is customisable at any time, including adding or changing component types, attributes and relationship types.
This feature is invaluable as many clients have their own favourite concepts and elements that they wish to model and in most cases other older established EA tools have fixed meta models that prevent this.

Powerful import and export to Microsoft Excel, Visio, PowerPoint and Word
This feature is also excellent since most organisations starting out with Enterprise Architecture modelling using office applications. Indeed some office applications such as Excel are oftne used to present the models.

Import and export via XML/XMI
This is important for sharing models with other case tools

Customisable charts and graphs
The charting and visualisation features are very useful for presenting important information to senior executives.

Evaluation tools
There are five pre-built evaluation tools that are excellent for analysing the enterprise architecture models in terms of Performance, Total cost of ownership, Modularity, Openness and Reliability.

* The Performance simulator uses discrete event simulation to calculate the theoretical load and response of your architecture. There are a series of outputs from this simulator, the most obvious of which are the Bandwidth and Response Time properties.
* The Modularity evaluator calculates the number of incoming and outgoing connections for each component.
* The Total cost of ownership evaluator calculates the Total Cost of Ownership (TCO) for the architecture.
* The Reliability evaluator calculates the mean time between failure of the system and availability of the system given the structure of the components and connections and their properties.
* The Openness evaluator determines the degree to which an architecture and its elements are 'open', that is, the ability of the system to handle replacement of components with minimal impact.

Implementation Libraries with pre-defined metrics
This is a feature that is not found in other EA tools. The Implementations contain pre-defined data about existing COTS applications, infrastructure and connections that are used in the evaluation tools

Abacus supports numerous Enterprise Architecture meta models and notations including:
