Best practice
When using "had established", ensure that the sequence of events is clear: the establishment occurred before another past action. For example, "By the time the conference began, the organizers had established clear registration procedures".
Common error
Avoid using "had established" if the action of establishing is still ongoing or relevant in the present. Use "has established" or "have established" instead. For example, instead of "The company had established a reputation for innovation," use "The company has established a reputation for innovation" if the company still holds that reputation.
