Defining an Operations Systems Architecture
CHANDLER, ARIZ., June 17, 2013 - Information systems provided by industrial software vendors are evolving constantly with new features and implementation strategies. The complexity and variety of available options make it difficult for many manufacturers to adequately discuss and compare software alternatives that may or may not meet their requirements.
Vendors typically promote architectures that are supported by the products or solutions in their suite or toolbox. If a manufacturer does not have a clear vision for the architecture of its operations systems, it often adopts the vendor's approach. This approach may be the best fit for the system being developed; however, in many cases it is not or the vendor's solution is not configured correctly.
In the absence of a target "To-Be" architecture, the vendor approach is inevitable. With the increasing reliance on system agility and associated operations management capability, the need to raise the bar is evi-dent. Best-in-class manufacturers must be able to understand their production processes and structures as a foundation for actual process improvement. Once understood, the As-Is and target To-Be architectures serve as a common basis for the discussion and mapping of alternatives.
This paper presents techniques for describing operations systems and engaging stakeholders in projects based on product-independent architectures with examples.
Taking this approach changes the game in vendor negotiations from product-centric evaluation to one in which operations system capability is the focus of discussion. The product selection process includes requirements and alignment to key design principles. Vendor responses are compared against a common operations model and strategy to build pragmatic MOM architecture.
A series of state-of-the-art enterprise and solution architecture concepts are presented, which can be used as a starting point for developing an operations systems architecture (OSA). This architecture can then be used to guide any project, from the smallest upgrade to the largest enterprise solution.
