Under which condition is the overall cause mandated for a Customer Satisfaction Survey?

The overall cause is mandated for a Customer Satisfaction Survey under all of the listed conditions.

When customer satisfaction indicators demonstrate lower performance, such as a Customer Satisfaction Index (CSI) below 85%, it highlights potential systemic issues that need to be addressed to improve service quality and meet customer expectations. Similarly, a recommendation rating of 'Probably Not' or 'Definitely Not' indicates that customers are unhappy with their experience, which can significantly impact future business if not rectified. Additionally, a position of 'Third' or 'Not in Top Three' in TCS rank may strongly suggest that a company is lagging behind competitors in terms of customer perception and satisfaction.

Each of these conditions points to a gap in customer satisfaction that necessitates a deeper investigation into the causes, making it essential to conduct a Customer Satisfaction Survey to gather insights and inform improvement strategies. Therefore, all the provided conditions justify the need to assess the underlying causes through comprehensive customer feedback mechanisms.
