Coating Development Decisions: Preserve Rejected Options and Their Reasons

Keep a concise record of why a development option was rejected or deferred. Without that history, a later team can repeat the same trial or revive an unsuitable idea because its original limitation is no longer visible.

Updated · NANOLAB Knowledge

The key distinction

The record should distinguish evidence-based rejection from a temporary commercial choice. An option may fail a requirement, remain untested or simply be outside the current scope. Those statuses have different meanings and should not be collapsed into a vague note that the sample was not good.

Practical checks

  1. Identify the option and the requirement or decision involved.
  2. Record the relevant observation and the reason for the outcome.
  3. State what new evidence or changed condition would justify reopening the option.

Example

Illustrative example: a bottle configuration is deferred because the intended filling equipment is unavailable, not because the package is technically unsuitable. A later project with different equipment may reasonably reconsider it. A precise decision record preserves that possibility without erasing the original constraint.

Scope and limits

Do not write speculative causes as established failures or discard inconvenient data. This guide does not require retaining every informal conversation. Preserve the decisions that materially shape the approved product and make their evidence understandable to someone joining the project later.
