According to Professor Fader, success in a customer-centric world arises through enhanced and/or more efficient levels of the following EXCEPT:1 pointCustomer experienceCustomer retentionCustomer developmentCustomer acquisition

The question is asking which of the following options is NOT considered by Professor Fader as a key to success in a customer-centric world. The options are:

1. Customer experience
2. Customer retention
3. Customer development
4. Customer acquisition

Without specific context or source material from Professor Fader's work, it's difficult to definitively answer this question. However, generally speaking, all four of these aspects are typically considered important in a customer-centric approach.

Customer experience refers to the overall experience a customer has with a company, which is certainly important in a customer-centric world.

Customer retention refers to a company's ability to retain its customers over time, which is also crucial.

Customer development refers to the process of developing and enhancing relationships with customers, which is certainly a key aspect of a customer-centric approach.

Customer acquisition refers to the process of gaining new customers, which, while important, is sometimes viewed as less crucial than the other aspects in a truly customer-centric approach. This is because a customer-centric approach often emphasizes the importance of retaining and developing relationships with existing customers, rather than constantly seeking to acquire new ones.

So, if one had to choose, the answer might be "Customer acquisition". But again, without specific context or source material from Professor Fader's work, this is just an educated guess.
