How to draw up a technical specification for a mouse so that they don’t buy a poop in the auction?
What fields to specify? In the terms of reference for the auction, after all, there is no way to indicate the model and manufacturer. I've never been involved in a purchase, what should I do to get a Logitech mouse and not a Defender?

Answer 1

The only thing that saves us from bureaucracy is its inefficiency.
(c) Eugene McCarthy

1. Take the mouse you want (no bigotry)
   
2. Take the mouse you don't want
   
3. Compile a summary table of tactical and technical characteristics
   
4. You are looking for fundamental characteristics that are inherent only, as you said, "turd" - enters a fad in the TK, so that the desired one fits, and not the desired one
   
5. Monitor the market in the same price category and below and repeat steps 3 and 4
   

An example that will be a little embarrassing:

1. resolution of the sensor (sensor) - at least 1000dpi
   is easy to justify - office work is highly intensive, a person needs to concentrate on work, and not miss the cursor past the desired line / character in the document. This is not a super requirement, just everything below is a mega-economy option for those who only need to sit in classmates. (although don’t answer directly like that, if suddenly one of the deputies at the session asks why the hell are such mice management or on behalf of whom you are making a tender there, cultivate it yourself)
   
2. cable length - at least 1.8 meters
   shorter length - this is for laptops, and you obviously have hospitals there and the system unit can be far under the table from the monitor
   
3. the number of buttons including scrolling / wheel - 3 or 4
   more - these are gaming mice (and if the tender suddenly passes, then also Chinese nouns)
   
4. device length - from 110 mm
   office mouse should not be pocket-sized, exclude compact devices that are not designed for long-term work
   

Defender did not find it within this framework) moreover, basically only Logitech passes the censor

Answer 2

dpi>1000 is enough)))

Answer 3

Monitor public procurement sites on the topic of what and how others buy and, on the basis of this, draw up your technical specifications
. I know that our superiors wrote "a keyboard in design not lower than the Logitech K120 class (presence and location of keys, the presence of a digital typing field on the right, and other standard ones, such as at Logitech K120), Russian + Latin layout, factory application of symbols "
And most suppliers stupidly didn’t take a steam bath and sent K120 and not any truncated rhythms
