XLDyn Mission

​The XLDyn mission is to develop system engineering tools that are fully integrated with an intuitive and easy to use graphical interface.  We have two modules developed in Microsoft® .NET 4.5 Framework.  XLSE for authoring OMG™ SysML compliant system models and XL1D for authoring and simulating detailed 1D multi-physics systems models.  The XLDyn technology is covered by three approved U.S. Patents, plus one pending

Motivation for System Engineering

Product success requires meeting or exceeding the customer expectations typically captured as VOC (Voice of the Customer) as well as other Stakeholder input.  VOC and Stakeholder input finds its way to requirements, which at each level of the design are balanced with design parameters.  One group’s design parameter becomes another group’s requirement, and those requirements need to be verified by a variety of methods and tracked over the life of the project.  Traceability from the VOC/Stakeholder input to the final validation is required to ensure success while project status needs to be current and easily available for everyone involved in the project.  Engineers need to define requirements, trace relationships, verify status against targets in one easy to use software tool.

Solution = XLDyn

​The solution to this is XLDyn as it provides the most integrated and easy to use MBSE (Model Based Systems Engineering) software for requirements and verification tracking.  XLDyn has a wide range of functionality needed by Systems and Simulation Engineers, and at the same time provides a “project view” capability that is ideal for managers and teams to keep abreast of project status.  XLDyn is the perfect tool for balancing designs at the system, subsystem and component level.

Why Excel?

​We choose Microsoft® Excel as the graphical user interface because it's a popular, ubiquitous engineering tool. Microsoft® Excel is used not only by engineers, but also by financial analysts and business executives on a daily basis everywhere. The chances are you already use Microsoft® Excel ​and are familiar with Microsoft® Excel's many features. As a new user, you will learn how to use XLDyn™ ​ that much quicker!
