About Gorilla Logic

Founded last year by the former executive management of Sun Microsystems’ Java Technology and eBusiness Consulting Practices

We provide tools, methodologies, and services to simplify the eBusiness application development process

66% of IT projects are not a success, representing $55 Billion of U.S. project waste – Standish Group

Poor requirements gathering, analysis and management lead to 60-70% of G2000 project failures in the U.S. - Meta Group

Outsourcing exacerbates requirements gathering problems due to geographic, language, cultural and other barriers

We can help bridge the gap between business and IT!

The Gorilla Logic Design Edition:Truly Agile Modeling

The interactivity and risk-reduction of iterative, rapid prototyping

Helps domain modelers to:

– visualize their designs

– validate requirements with end users

– communicate functional specifications with developers and testers

With the design rigor and clarity of model-driven development

When the delivery team is not co-located with users

The Gorilla Process

Advantages of the Gorilla Execution Engine

Standards-based

– Little incremental effort for immediate results

Users can “drive” the application simulation and suggest improvements

– “I’ll know it when I see it”

– Verify functionality before coding begins

No effort is lost to create a prototype

– the result is a complete and correct functional specification

The ultimate means of communicating functionality

No need to change modeling tools

So, how does it work?

This is the source code

Our sales force automation application – Our sales force automation application – Go SellGo Sell

Directly Executed model, fully functional app

Go Sell is a complete Contact Management/Sales Forecasting application.Time to model: 4 hours. Time to implement: 12 seconds.Time to model: 4 hours. Time to implement: 12 seconds.

With Gorilla Logic,

The Model Is The Code.

Executable Domain Models The domain model contains the most important part of

business systems: Business concepts!– Relationships, Ownership

– Business rules

– No implementation structures

And yet, in the traditional view, a domain model is:– A picture in a document on a shelf

– Incomplete, ambiguous, imprecise, out-of-date

– Only code is “real”, because it really does something

Gorilla Logic view– The domain model is the program

– Executable, verifiable, testable

A Few key features of the Gorilla Execution Engine

Transaction management

Support for complex Business Rules

User interface generation and customization

Interactive shell for debugging

XML message model mapping

Gorilla Logic Delivers!

The business specifications are the program– The Gorilla Execution Engine directly executes

highly declarative business model diagrams

– The only product that generates complete systems from business-centric UML domain models, instead of line-by line creation of huge bodies of code

Verify functionality before any coding begins

Enables cost-effective IT development without the risk of failure

Project References

"I was very impressed with the ability to get feedback from customers on a design immediately. Gorilla Logic's offering has the potential to be a high-value, low learning curve toolset not just in Inception but throughout the software lifecycle. "

-Tim Seltzer, Senior Java Architect, Sun Microsystems Inc.
