"The Sequoia System Model facilitiates the use of “best-of-breed” solutions
from competing OEMs and System houses."

Purpose

The Sequoia ITS System Model occurs as a consequence of the Business Model's "functionality" and "performance" requirements; ie. the System Model exists to provide the solution to the needs identified in the Business Model.

The System Model describes the software and hardware needed to implement the solution; thereby completing the loop back to the Commercial Model, by identifying the capital costs of developing and implementing the solution.

Functionality

The "functionality" requirements of the System Model are expressed as "Use Case Realizations". These realizations are the UML (Unified Modelling Language) expression of:

These elements together comprise the Software Architecture of the system solution.

Performance

The "performance" requirements of the System Model are expressed as the "Technical Architecture" of the System Model, which identifies the nature and strength of the hardware components, and their method of aggregation, required to provide a solution capable of achieving the nominated performance.

This architecture encompasses, generally:

and, specifically for an ITS:

Multi-Vendor Integration

Sequoia's System Model incorporates the following detailed design elements:

These 'interface' elements facilitate the concurrent development of component solutions, by independent vendors, potentially spread around the world, with the assurance that all parties are developing to interfaces which are (a) well-defined, and (b) consistent with the system-wide objectives.

Sequoia’s System Model provides a comprehensive and cohesive design solution.
