How to transfer information to the development team?

I am a ui team lead.

I detected that the topic of "how do you want the graphics?" is a very hot topic in my company. And I find myself always giving the same explanation.

I would like to give like a "checklist" for the PMs and the designers we work with to make the work more efficient and fun.

Currently there's this constant ping-pong in emails between us and PMs. I would like to get rid of that..

Thought about the following list (several of the items I gathered so far..):

• The design should be web and mobile friendly. (yes - sometimes we get some crazy design that require us to use mostly images even with all the power of CSS today..)


• Flat design is good. - obviously a recommendation.


• Images should have transparent background.


• Formats:
  
  
  
  • The original PSD file
  
  
  • Each layer in PNG with transparent background.
  
  
  • Icons and flat images should be in SVG, and if possible - as a font. (we usually convert to font ourselves).
  
  
  
  


• General guideline of the design should be attached.
  
  
  
  • color palette and the purpose for each color: Title, subtitle, text, disabled items, actions items.. etc..
  
  
  • important alignments guidelines - sometimes we miss the need for things to align whereas the designer feels they based the entire design on that. This usually affects the HTML structure as well - so it is very important to have common grounds on this ASAP.
  
  
  • Error messages display (ALWAYS MISSING! no one designs the errors..)
  
  
  
  

And then a whole different section for emails :P

We usually develop web design, but none web might be required too in the future.

Seems to me like someone probably already made such a list and I am reinventing the wheel.

What is the standard for passing the grail from the designer to the dev team?
