triiger,properties,validators,post functions,conditions which executes first 

[Nic Brough -Adaptavist-]

Two of them do not have an "order", they don't have a timing cycle

• Properties are not actions, they're data that sits in the workflow (and other places) providing extra data, which is read by other things.
• Triggers are not quite actions either.  They are dedicated hooks that allow actions (generally external to Jira, and usually build and automation tools) to start workflow transitions.

The other three do have a timeline.

• A condition is run when deciding whether someone or something can use a transition at all
• A validator runs after any user input on a transition (which may be as simple as "do transition", but could include data entry on a screen).  It usually checks for bad data
• A post-function runs at the end of a transition, after it's passed all validators and is going to happen.  Typically they update data - the five system ones for example actually save the changes, update the index, fire events etc

I think, it follows:

1. Properties
2. Triggers
3. Conditions
4. Validations
5. Post Functions
