Trigger Order of Execution In Apex

In Salesforce there is a particular order in which events execute whenever a record is changed or inserted. Following are the steps of trigger execution:

Step 1:  Load the original record or initialize on insert.

Step 2: Override the old record values with the new values.

Step 3: Execute all before triggers.

Step 4: Run the system & user-defined validation rules.

Step 5: Save the record but do not commit the record to the database.

Step 6: Execute all after triggers.

Step 7: Execute the assignment rules.

Step 8: Execute the auto-response rules.

Step 9: Execute the workflow rules.

Step 10:  If there are workflow field updates then execute the field update.

Step 11: If the record was updated with a workflow field update then execute before and after triggers created on the object in the context again but only once.

Step 12: Execute the processes and flows on that record.

Step 13: Execute the escalation rules.

Step 14: Update the roll-up summary fields & cross-object formula fields.

Step 15: Repeat the same process with the affected parent or grand-parent records.

Step 16: Evaluate criteria-based sharing rules.

Step 17: Commit all DML operations to the database.

Step 18: Execute post commit logic such as sending emails.
