Build a requirements brief
Keep requirements, evidence and open questions together. Entries stay in this page’s memory until you leave or reload; this worksheet does not submit them. Download a text copy for your own review. Do not enter confidential or controlled technical information.
Connect the requirement to the material
Once your team has defined the application requirements, review the exact product’s available documents. Ask about packaging, lot evidence and unresolved sourcing questions; an industry listing is not an application approval.
