In addition to reviewing the implementation plan before execution, you have the option to make changes to the context Appfire QueueZero used, rerun the resolution process, and have QueueZero generate an updated plan. There are two ways to make changes so that a plan can be refined: update any **Assumptions** made during the planning process, or add additional details to the context.

Assumptions are covered in the next section; additional details can include updated Descriptions or other work item data, updated or additional knowledge sources such as Confluence pages, and updated files in the code repository. 

To refine an existing plan after updating the Assumptions, the work item, or the associated knowledge sources, simply click **Resolve** or **Resolve again,** and a new plan will be generated. 

## Assumptions

![Review and modify Assumptions made during Resolver plan implementation](media://2abf1352-4b35-4b92-9df3-1af37c461501)

During the planning phase, your model may encounter context about which a decision must be made - these points are called **Assumptions**. Rather than interrupt the planning phase to request additional information, QueueZero stores the options the model would normally present to you and selects the best option based on the total context available.

Assumptions, however, can be modified during the review of the implementation plan. 

To review Assumptions, expand the **Assumptions** panel and then expand each of the categories to review the specific choice QueueZero made during planning. Select new choices where needed; your selections are saved automatically. 

Click **Resolve Again** to start the planning phase again using the new context.
