The Decision Tree Model feature allows a user to make use of their own custom decision tree. The model can be embedded into any Food Safety Plan and be used as part of a hazard analyses.
As opposed to the industry standard CODEX decision tree which can only have two outcomes (not CCP or CCP) you can now build your own decision tree which may have virtually any outcome you like.
1. Add Model Details
- Give your Decision Tree a name, for example; “FSSC 22000 Decision Tree”
- If you manage a large portfolio of plans and need to use different models you can easily categorize them into folders. These plans will then be immediately accessible for future use in different plans.
2. Define your decision tree
- The first step in defining a tree is to add the necessary number of questions. Each line in the table corresponds to one question in the decision tree.
- Place questions for the decision tree here.
- In the ‘Yes Decision‘ and ‘No decision’ columns there are two possible actions when the user selects an option from the dropdown list. The dropdown list contains items for pointing your decision tree to a later question – this is the case with question 3 where we want the decision to proceed to question 4 in case the answer to this question is “Yes”. If you don’t want the software to proceed to a later question but rather identify the step as a CCP, OPRP, or QCP or some other kind of control point you can simply type the outcome into the same field. The question 1 for example would lead the decision tree to output “OPRP” if the user selected “yes” as an answer.
- If the outcome of an answer is something other than “Go to xx” the software wants to know if this decision tree outcome should prompt the hazard analysis for monitoring details. If you were to read the first line of the above table as an instruction it would say “Is the step an OPRP? If you answer “Yes” then the outcome of this decision tree is that this step should be considered an OPRP and the user should later provide information about how they plan to monitor this OPRP but if you answer No then we will continue to question 2.“
- Note: The outcome of the decision tree can also be something else than a kind of control point – for instance you might conclude that the answers provided don’t really make sense and that the user would need to make some modification to the process step.
