prototypedeadline

A prototype deadline, sometimes written as prototype deadline or prototypedeadline, is a scheduled date by which a prototype of a product or system must be completed. It marks a key milestone in many development processes, signaling that a concept must be demonstrable, testable, and ready for evaluation. The concept is used across software, hardware, and research projects to separate early ideas from a tangible, reviewable artifact.

Purpose and scope: The prototype deadline helps align teams, allocate resources, and manage expectations with stakeholders such as sponsors, customers, or regulatory reviewers. It provides a fixed point to assess feasibility, gather user feedback, and decide whether to pivot, extend, or freeze features for later stages.

Setting and management: Effective use requires clear deliverables and acceptance criteria, such as functional demonstrations, performance benchmarks, or documentation. It should be tied to a realistic schedule with risk buffers and dependencies identified. Iterative approaches often use multiple prototype deadlines, for example for alpha or beta prototypes, before the final product deadline.

Relation to broader process: The prototype deadline typically precedes the final shipping or release deadline and is often part of a stage-gate or agile cadence. Misalignment can lead to rushed builds, quality issues, or scope creep; conversely, a well-placed prototype deadline can improve learning and decision-making.
