Using equivalent graphics and natural language, OPCAT provides system engineers, architects, analysts, designers, product managers, customers, and engineers from different disciplines, with an innovative comprehensive, consistent, conceptual modeling language and environment.

Founded on Object Process Methodology (OPM) and systems theory, OPCAT provides a unique software environment for complex systems development and lifecycle support.

OPCAT

Systems are becoming increasingly more complex and multidisciplinary, with many stakeholders involved at different managerial levels and development stages. This situation makes it is ever more difficult to sustain agile development of complex systems and products of superb quality.

OPCAT provides system engineers and architects, product and project managers, customers, and engineers from all the pertinent disciplines, with a comprehensive modeling and lifecycle support solution that features a dual graphics- and natural language-based conceptual modeling language that is intuitive yet formal, easy to understand and quick to learn. The underlying Object-Process Methodology with its bi-modal language greatly facilitates communication among stakeholders (managers, customers, developers, and subcontractors) and across engineering disciplines (software, hardware, human factors, etc.) throughout the entire span of the system's lifecycle.

OPCAT unique state-of-the-art solution incorporates the following features:

• Single model that enables clear and concise expression of hardware, software, humans and regulation.
• Complexity management by refinement/abstraction mechanisms that include in-zooming/out-zooming, unfolding/folding and suppression/expression.
• Animated system and product simulation for design-level conceptual debugging and effective early error avoidance or trapping, resulting in huge tangible time and money savings down the road.
• Automated documentation, code generation and automatic document referencing mechanism.
• Import and validation functions for system evolution that follows configurable organizational development policies.

OPM

Object-Process Methodology (OPM) is a comprehensive approach to conceptual modeling for system development, evolution, and lifecycle support. OPM incorporates the static-structural and dynamic-procedural aspects of a system into a single unifying model. OPM features a clear, compact, and concise set of symbols that form a language for expressing the system's building blocks and how they relate to each other both structurally and dynamically.

OPM represents the two things that are inherent in a system: its objects and its processes. Objects are what a system or product is, and they may have states. Processes express what a system does - how it transforms the objects, where transformation means generation of new objects, consumption of existing objects, or change of their state. The OPM model shows the structural relation and procedural links between the system's building blocks at any needed level of detail. The single model provides for clear and expressive animated simulation of the OPM model, which greatly facilitates design-level debugging.

OPM has another fundamental advantage: it represents the system simultaneously in both graphics and a (subset of) natural language. The two representations are completely interchangeable and convey the same information in cognitively complementary modes. The advantage in this approach lies in appreciating the human limitation to the understanding of complexity. As systems become more complex, the primary barrier to success is the ability of the human systems engineers, architects, analysts, and designers to understand the inherent complexity of the interrelationships. By representing the system in both textual and graphical form, the power of "both sides of the brain" (the visual interpreter and the language interpreter) is engaged.
