SPECbestand

Specbestand is a Dutch term that refers to a document or file that records the specifications of a product, system, or project. It serves as a reference for what must be delivered, including the essential requirements, features, and constraints. A specbestand functions as a communication tool among designers, engineers, suppliers, and customers, and can be used to guide development, procurement, testing, and verification.

Typical contents of a specbestand include the product name or model, intended use, performance requirements (such as dimensions, tolerances, power, speed, capacity, or throughput), materials and interfaces, interoperability, and compliance with standards. It often also covers testing and acceptance criteria, quality attributes, packaging and labeling, as well as roles and responsibilities, references, and a revision history. The format can vary from a traditional written document to structured data files in formats like CSV, JSON, XML, or YAML, depending on the context and the tools used.

Lifecycle and governance are common features of specbestanden. They are usually treated as living documents that are updated through formal revision, approval, and version control processes. This helps ensure that all stakeholders work from the same baseline and that changes are traceable.

In practice, a specbestand might appear as a product specification in manufacturing, a software feature specification, or a procurement specification in public or private tenders. The exact terminology can differ by sector, with related terms such as technical specification, spec sheet, or bestek also in use.
