As we all know, a lot of things can happen when executing a recipe in the Lab. We can make mistakes and we also might want to make "an exception to the rule" of the recipe itself. 

Thankfully, ONE Lab ​​​​​​​offers the flexibility to allow (or not) such exceptions and makes sure the reviewers always know exactly what happened in the lab: ​​​​​​​

• With Compose ​​​​​​​Signature Policies, you can enforce users to sign on specific events (such as Data Modification, Out of Limits or Material Expiration and Substitution) during execution.
• In the Review by Exception ​​​​​​​panel, the reviewer can easily see what happened and the reasons given by the operator
• In case of audit, Recipe Report ​​​​​​​can also be generated in an exportable format.
