I discovered Enterprise Architect while teaching Rational in Stockholm in 2001, and was an immediate and enthusiastic convert. Even back then it offered me a remarkable combination: of precision, collaboration and flexibility at a very low cost. Since that time 

“Sparx Enterprise Architect is the best, most complete tool I've ever used.”

I use Enterprise Architect for ba modeling activities. I use class diagrams for business domain models, state diagrams for workflow, activity diagrams for business process, use cases and actor diagrams. I add text for each element. 

My team and I have been active in enterprise agile projects since the mid-nineties. We have assembled this broad knowledge and experience in our agile Accelerated Delivery Platform (ADP). 

Sparx Systems has done a great job with their implementation of my rapid delivery methods as part of the Zachman Framework add-in to their Enterprise Architect modelling tool, and has delivered great functionality in a very short timeframe.

I’d like to congratulate you and your staff on delivering what I consider to be probably one of the most valuable software products in support of systems engineering in existence, Enterprise Architect.

“I've used Enterprise Architect for years, and recommend it to my clients considering for UML modeling tools. It's is a great tool, it provides all the essential features and more at a very reasonable price. The ability to store your model in a shared database is a tremendous timesaver.”

“EA lets you describe the parts and pieces of what you want to build, and how they are interrelated. It then draws the pretty picture of what you're planning to build… or creates a web site of the model with a single click… or creates a word processing document… or exports to an XML file… or plugs into Eclipse… or generates stub code and DDLs… or… well, you get the picture.”

“I would have to say that EA has one of the most comprehensive and exhaustive feature sets of any UML lifecycle tool at any price. The performance is fast and everything is conveniently located in a single interface. Thanks for a great product at a price that is accessible to everyone!”

“I tried using Rational Rose the other day for the first time after using EA -- and it was amazingly weak by comparison. You've got a very capable product at 1/15th the cost!”

“Thank you, You have a great product.”

“Enterprise Architect has been a surprisingly effective and easy to use UML tool. EA has made easy work of a variety of business process modeling and software development projects accomplished for our customers. For a relatively new tool, EA is quite reliable and, best of all, handy. Our customers have been very impressed with the quality of documentation produced by EA. 

“I love this tool. I've been more productive within the first 30 minutes of installing than I ever have with Visio.”

...Can I say how impressed I am with Enterprise Architect, particularly with the scope of functionality and its support for modeling the entire development lifecycle, including multi-user/team aspects .

To be honest, EA is a fantastic product… the price you charge is way below what it is worth!

I have used many UML tools, from Rose, Together Control Center, Embarcadero and Quest, to Poseidon and other open source tools and your product is the best - hands down. The feature set is so rich it takes a team to exercise it all!

Sparx Systems seems like much more of a 'developer company's company'. By that, I mean that the forums appear to be full of examples of EA designers and developers immediately addressing customer problems and needs. You just don't find this kind of accessibility from many of the well-known vendors.

I wanted to tell you that I have been using Enterprise Architect for several months now and am continually blown away by it. I have used nearly every UML tool on the market at one time or another -- from Rose, XDE, and Together to MagicDraw, Eclipse, Poseidon, and ArgoUML -- and find that nothing can compare to the power, ease-of-use, and rock-bottom price of Enterprise Architect.

It's... great! My decision to purchase EA was confirmed within 20 minutes. I opened up EA and expressed a core design without reading one line of the excellent documentation. In my book, that's the sign of a great product. I have used many other CASE tools for UML... EA eclipses all of them.

I bought EA a few weeks ago after looking around for a UML tool and EA seemed to have it all - great functionality, rock bottom price. I've been using it for the last week or so developing a logical model and this tool is so easy to use and offers an incredible depth of functionality. EA is, without a doubt, the developer tool bargain of the century.

I think that Enterprise Architect is a comprehensive, feature-rich and easy to use integrated design tool. It is a developer's dream come true, with an excellent cost-quality advantage and definitely will benefit any organisation which is interested in unleashing the power and benefits of OOA/D using UML.

Enterprise Architect greatly helps expedite X12 modeling initiatives for both existing EDI transactions and new and emerging CICA messages. We expect it will continue to benefit our development activities and its value to X12 cannot be overstated.

The Association for Retail Technology Standards (ARTS) has selected Enterprise Architect as its tool of choice to develop and share their work on UnifiedPOS 2.0 model, as well as WS-POS 1.1, Business Process Modeling maps and various XML Schemas.

We are using Sparx Enterprise Architect to model the development of an energy station for transport, over a period of five years, using best practice technology development, and outsourced ICT data centre infrastructure for electricity, hydrogen and CO2 metrics. Sparx EA allows us to model complex information flows around the production and supply of renewable energy for both the electricity grid, and for powering up hydrogen and electric vehicles.

Although my project' languages may be C#, Java, or C++, the one thing that remains a constant is my use of SPARX EA. To effectively execute my roles of Enterprise and Software Architect I must have SPARX EA as my primary tool.

I've been using Enterprise Architect for 9 years now and it is my preferred UML modeling tool. I often use EA for constructing UML class models during interactive modeling sessions with customers. As they articulate the requirements, I construct a class model before their eyes. When we finish, I suggest that they buy a copy of EA, if they don't have it already. It's a great situation -- EA provides me with a professional tool for constructing models and my customers with a low-cost tool for maintaining models.

I found EA incredibly powerful and above all, flexible. The documentation that it produces is excellent ... It significantly reduced the amount of duplicated work that I had to do. ... I would now find it hard to justify the expense of Rational or Popkin's products. An excellent product at a reasonable price with impressive, after-sales, personal technical support.

Enterprise Architect (EA) is one of the best tools in the software modeling space in today's market. It offers both, a comprehensive set of languages and powerful cross modeling capabilities that can combine multiple modeling platforms in one diagram, model, or project. As a result, time-to-market, expenditure reduction, and asset consolidation are a few, yet, outstanding benefits of EA. In addition, the powerful EA nimble features contribute incalculable technological and business value to our firm and to the rainbow of clients we serve in a variety of industries.

We find Enterprise Architect a quality tool that offers good functionality for an excellent price. Enterprise Architect offers possibilities, which more expensive tools not always offer. The integration of a design environment and project management support, the option to calculate project estimates, glossary support and the possibility to store defects and solutions related to maintenance makes Enterprise Architect a valuable tool. It is the integration of these functions we like best.
