Before the sample: define your needs
A clear surface, task and assessment setting make the sample discussion more useful.
Use scenario
Describe where and why you will use it. Specify the surface finish, soil type and cleaning agent; leave unknown details open.
Assessment plan
Define the conditions and what you want to observe. Do not confuse observations with technical test results or suitability approval.
Project scope
Add desired dimensions, quantity, packaging, destination country and date if known. These are request inputs, not stock, minimum order or delivery commitments.
