====== Quality assurance (Parameter database) ======

A parameter instance (a set of values belonging to a specific type of parameters and a specific scenario/case) has a usability status.

The usability status positions the parameter in the quality assurance process.

^ Draft   | Data has not been quality assured.        | 
^ Under revision   | Data has been assigned to a reviewer for review. |
^ Returned from revision | RData has been reviewed.        |
^ Accepted   | Data has been reviewed by a reviewer and accepted by an administrator. |
^ Rejected | Data has been reviewed by a reviewer and rejected by an administrator.          |

**The quality assurance process**

The quality assurance process can quickly be summarized by the following steps:

A user with the role **Operator** or **Administrator** assigns values to parameters, either directly in the user interface or by importing values from Excel. The parameters now have the usability status of **Draft**. Only parameters with the usability status of **Draft** can be edited.

The user submits the parameters for review and assigns a user with the role Reviewer to perform the review. The parameters now have the usability status **Under revision** and cannot be edited.

The **Reviewer** logs into the database and reviews the values. The **Reviewer** can comment on each parameter and can also recommend or not recommend the parameter. When done, the Reviewer finalizes the review by changing the usability status to **Returned from revision**.

An **Administrator** can now either **Accept** the reviewed parameters or **Reject** them.


Only parameter values that have made it through the full quality assurance process are considered quality assured. If changes need to be made to a parameter with the usability status **Accepted** an administrator must either change the usability status back to **Draft**, or a new instance must be created.
