Custom properties setup in Onshape

Hello!
We are looking to setup our Onshape account to a potential migration from solidworks/3dexperience. We take this transition for an opportunity to upgrade our standard and CAD methodologies. I would like to know if some people are willing to share there custom properties setup for part and assembly on Onshape ?
We are OEM for packaging equipment. We think the properties need to be kept as simple as possible and let the ERP manage the more "administrative" properties like "cost", "lead time", "alternative supplier".
Also, on Onshape there are possibilities to add properties on a lot of different things! If you have some "must to", do not hesitate to share.
Here is the properties we are planning to setups :
Thank you :)

I'm confused why you would encode manufacturing steps within the properties. The type is list. Can you give examples of what would be captured in these properties?
How to do document manufacturing processes? Are these part properties or assembly properties? Wouldn't this info normally be part of a part drawing, or SOP (standard operating procedure) document?
Hello S1mon! The "important manufacturing step" is to specified steps I want to be respected to obtain the final part. By example, the finish may be "Powder coated" but some time when I want a primer or sandblast step before powder coating. Another example is about aluminum anodization, often I want a glass bead #120 treatment before anodization to obtain a very uniform finish.
Habitually this is for parts but some weld assemblies can have those properties also.
Of course this information may not need to be a "property" and sometime there are notes in the drawing if more detail is needed. But by experience, the subcontractor may not read carefully those long notes and a short list with the steps needed is appreciated. But I think this is useful in some other way :
Here an example where the steps are shown into my drawings :
At this moment, we are looking to Implement an ERP and we are facing some redondance with "routing" from the ERP standpoint and those properties.
Your Idea to have SOP is a good one!
In practice, this makes a lot of sense, but some would argue that a part drawing should specify only the properties and measurements that you need to guarantee a good part which can then always be assembled into a good product. For instance, your second example specifies laser cutting as the first step. There might be a situation where molding, milling, or punching would create a more accurate, less expensive part.
There are definitely many part drawings that I've done in my career which assume a production process, but I would also be careful never to over-specify something which could prevent a part from being made more inexpensively while still achieving the critical to function specifications that you need.
