The product backlog should be ordered based on the value of the items being delivered. This is because the main goal of any project is to deliver the highest value to the customer as early as possible.

Here are the steps to order a product backlog:

1. Identify the Items: The first step is to identify all the items that need to be included in the product backlog. These items could be features, functions, requirements, enhancements, and fixes that need to be developed for the product.

2. Prioritize the Items: The next step is to prioritize these items. This is usually done by the product owner, who considers factors like the value of the items to the customer, the cost and time required to develop the items, the complexity of the items, and the risk associated with the items.

3. Order the Items: After prioritizing, the items are ordered in the product backlog. The items with the highest value are placed at the top of the backlog so that they can be developed first. The items with lower value are placed lower in the backlog.

4. Review and Update: The product backlog is not a static document. It should be regularly reviewed and updated. As new items come up, they should be added to the backlog. As items are completed, they should be removed from the backlog. And as the value of items changes, the order of the backlog should be updated.

So, while complexity, team choice, and risk are factors that can influence the order of the product backlog, the primary factor should be the value of the items being delivered.
