perstage

Perstage is a term used in multiple industries to describe a design and management approach in which work proceeds through a sequence of discrete stages, with activities, checks, or resources applied at each stage and outputs passed to the next. The term is not standardized, and its exact definition varies by context.

Etymology: The word combines per- meaning through or at each with stage, signaling a recurring, stage-by-stage progression.

Applications and usage:

- In manufacturing and logistics, per-stage processes emphasize stage-wise inspection, quality control, and capacity planning, allowing traceability of parts and decisions at each step.

- In software development and data processing, per-stage pipelines divide work into stages (for example, ingestion, validation, transformation, loading), with validation checks and error handling at each stage.

- In project management and governance, per-stage budgeting or decision gates divide a project into phases, with authorization required to proceed to the next stage.

Advantages: Improved traceability, risk management, and quality control through explicit stage boundaries; easier pinpointing of defects or bottlenecks.

Limitations: Lack of formal standardization leads to inconsistent usage; terminology may overlap with similar concepts such as pipeline processing or stage-gate models.
