This chapter covers
- Diagnosing problems with the product after it’s delivered to the customer
- Finding remedies to product problems
- Getting and using feedback from customers
- Revising the product based on known problems and feedback
Figure 12.1 shows where we are in the data science process: revising the product after initial feedback. The previous chapter covered the delivery of a product to your customer. Once the customer begins using the product, there’s the potential for a whole new set of problems and issues to pop up. In this chapter, I discuss some of these problem types and how to deal with them, and I talk about customer feedback and revising the product based on the problems you encounter and the feedback you receive.
Figure 12.1. The second step of the finishing phase of the data science process: revising the product after initial delivery to the customer
Despite your best efforts, you may not have anticipated every aspect of the way your customers will use (or try to use) your product. Even if the product does the things it’s supposed to do, your customers and users may not be doing those things and doing them efficiently. In this section, I discuss a few causes for the product not to be as effective as you would hope, and I give some suggestions for how to recognize and remedy them.
