Semistandardization

Semistandardization is a strategy in standardization practice that formalizes a subset of elements as standardized while leaving others deliberately variable. In contrast to full standardization, it targets core interfaces, data representations, and procedures that must be interoperable, while permitting local adaptation of noncritical components. The concept appears in manufacturing, software engineering, information governance, and policy design, where the aim is to achieve interoperability and scale without suppressing innovation.

Methodologically, semistandardization relies on identifying a core set of standards, creating modular architectures, and establishing governance and conformance mechanisms. It often employs reference architectures and open standards for stable interfaces, while treating other elements as configurable or customizable. Implementation can involve standardization bodies or industry consortia that publish core specifications and provide testing and certification.

Advantages include reduced integration costs, faster time-to-market, and clearer interoperability boundaries. It also supports customization and local optimization. Challenges include potential fragmentation if the nonstandardized parts diverge, the overhead of managing evolving core standards, and the risk that the core becomes insufficient as needs change.

Examples include automobile platform programs that standardize engine interfaces while allowing region-specific tuning; software ecosystems that standardize APIs and data formats but allow feature differentiation; and enterprise IT where a shared service catalog uses core service interfaces but customizable workflows.
