"A Simplified Approach to IT Architecture with BPMN: A Coherent Methodology for Modeling Every Level of the Enterprise" distills the insights a seasoned IT professional gathered over the course of thirty-five years spent studying, designing, deploying, critiquing, and refining IT architectures. This approach, rooted in models, follows a logical pro...
A precise definition of IT architecture and its relationship to engineering is described. The components used to define architecture are generically defined along with relationships among these components. These concepts are then used, along with a particular architecture viewpoint and system context to document an example of architecture component...
Dynamic business environments require concurrent, distributed, and flexible architectures that must provide an agreeable level of reliability and acceptable level of trust. A three level undisruptive business driven planning process has been formulated using a risk analysis model that provides a justifiable direction for implementing a low risk sol...
This paper defines an enterprise security model that provides a cohesive structure for the definition and implementation of security services. The complete framework is described, but with a focus on subjects, and protected objects and how access is controlled. Multiple layers of security are defined, building upon the “defence in depth” concept, a...
This is a new and simplified methodology for the definition of IT Architectures, and is described in the book "A Simplified Approach to IT Architecture with BPMN" ... one of my published references. The methodology as defined is a starting point, but so much more could be added over time, including more patterns and supporting materials, but most of all tools support is needed. Current work focuses on these aspects and the sort of tool that would best support this new approach. See: http://www.unified-am.com/
