If performance is less than industry standard, and trending negative, then its time to do a turnaround.
You can't escape logic. In a turnaround, the performance of a business unit is returned to a level at or above industry standard or to a level specified by the owner's operational plan. In addition, any declining trend in performance is reversed. But don't trust just anybody to lead it. An external, independent practitioner with more than one turnaround under their belt is what you are looking for. You can start your search right here.
IFCorp has successfully performed turnarounds for NCR, AT&T, Church & Dwight, and others.
