Product Versioning

I like the Mark system as a simple and clear versioning method for products. Here's the format:

Mk1 v3

Rules

• Use abbreviation "Mk"
• Immediately follow Mk by a positive integer, without a space, like "Mk2"
• Always add one space between mark and version number
• Use lowercase "v" for version
• Immediately follow v by a positive integer, without a space, like "v5"
• Mark number MUST be incremented if any backwards incompatible changes are introduced.
• Version number MUST be incremented if any changes to production processes are introduced.
• Version number MUST be incremented if any changes to swappable sub-assemblies, parts, or hardware are introduced.
• Mk0 is used exclusively for prototypes.
• Naming prototypes is wild west stuff. Anything goes.

Prototypes

• Mk0 v1 TopHinge
• Mk0 v5 NoHinge
• Mk0 v12 Molded
