Valve Filter

[irene_livens]

A very simple idea, the same principle as the existing filter but there is only one output (true) and there is an on / off button. This could gives users the opportunity to put in a "what-if" gateway into their workflow. 

For example, your stakeholder has asked you to use 'all the data'. Whilst building the workflow, you notice that excluding 2016 data gives you a more accurate / representative end result. However, it is not necessarily your decision to exclude the 2016 data. You put in the Valve Filter tool:

Valve Filter On = Excludes the 2016 data.

Valve Filter Off = Allows all data to go through.

You are able to turn the filter on and off, run the workflow and see / demo different end results (instead of using a traditional filter and creating a separate workflow or a duplicated arm of a workflow).

Until your workflow is complete, you do not always know the full impact of the parameters / decisions you make along the way. The Valve Filter could give users more flexibility.
