Just because you can do something, doesn’t mean you should, and that’s the case with nested ternary operations. Nesting ternary operators results in the kind of code that may seem clear as day when you write it, but six months later will leave maintainers (or worse - future you) scratching their heads and cursing.

Instead, err on the side of clarity, and use another line to express the nested operation as a separate statement.

Noncompliant Code Example

Public Function GetReadableStatus(job As Job) As String
    Return If(job.IsRunning, "Running", If(job.HasErrors, "Failed", "Succeeded")) ' Noncompliant
End Function

Compliant Solution

Public Function GetReadableStatus(job As Job) As String
    If job.IsRunning Then Return "Running"
    Return If(job.HasErrors, "Failed", "Succeeded")
End Function
