Mastering Variety in Industrial Production, Issues a Challenge for Industrial Architectures and Drives the Requirement for Platform Strategies

For many businesses, variety (or choice) is core to the strategy where its effect cascades down to the execution level (as well as upstream in the B2B value chain.) The operational challenge of variety (or variability) is that it can create waste and inhibit velocity. The challenge and opportunity is with companies, especially as they move to unified value chains (multi plant manufacturing). “How do you manage this Variability, so that production consistency, agility and increased production output are achieved?”

“Standardization is not a business goal – it is a means to an end.
The goal of business is to make a profit.”

Thus, any standardization effort must distinguish between the different types of variety in a way that maximizes profit without constraining the business strategy. Thus, the business challenge can be summed up (using the Food & Beverage example illustrated on the above) as follows:

• Mastering necessary variety: More brand choices drive the number of order line items (SKUs) and master recipes, which in turn drive the resulting plant-level recipes that must accommodate the variations in process equipment as well as ingredients. This type of variety is necessary and must be mastered in order to survive and succeed against the competition. Other “necessary variability” are material composition variance from different suppliers or regions, raw materials will vary. Location delivery in skus due to language, for example, the same product will have to be delivered to different countries in different language or different quality requirements. All must be mastered to optimized production.

• Accommodating unavoidable variety: Situations like M&A make it difficult to standardize on any single automation vendor, where “rip-and-replace” isn’t economically viable despite engineering’s desire for a more homogeneous environment. The growing one in this area is the “changing workforce” how do have a system that can accommodate a changing, (rotating) workforce while maintaining timely decisions and consistency in actions.

• Eliminating unnecessary variety: Anything other than the above two scenarios would be eligible for standardization.

This challenge is driving companies to adopting “platform strategies” that abstract the variability and can absorb variability while provide a platform of services that enable standards to be built on. Providing the architecture for “sustainable innovation” through managed standards that can evolve over time. The word of standards can be operational models in supervisory for alignment of context and structure, as well as operational actions to guide users through tasks in a consistent way. Also, configuration of control strategies should be over multiple vendors, where common control standards for process can be deployed over multiple controllers but managed in structured way.

Does this mean one platform? NO, not for the industrial landscape different layers of the industrial operations landscape have different roles. Providing different services and different ability to absorb variety, but the common services between these platforms must enable them to “tightly aligned but loosely coupled”.

 As we have pointed out the key to success in this dynamic but changing world is the ability to “Master Necessary Variety” in your business, while “Accommodating Unavoidable Variation”, eliminating all other variation for efficiency.
