Trouble with Specifications

Specifications for lasers and other photonics products are essential for the process of buying such things. Nevertheless, many do not properly deal with them:

Many product specifications by suppliers lack quality – they are incomplete, not sufficiently clear, etc.

Buyers are often not aware of what they really need. For example, they forget essential requirements.

Various problems can arise:

Due to a lack of clarity, tedious communications between supplier and buyer are required.

Product specifications raise expectations which cannot be met.

Conflicts can arise over such issues.
