I disagree. If you ignore the actual value your product provides to the final consumer "this banana is delicious", you'll come up with solutions that diminish that value. The only reason why blending whole bananas (peel and all), and sending that slop in an unrefrigerated shipping container isn't even considered as an option is an understanding of what the banana-buyers want.
Nobody is proposing ignoring what people will buy. What I said is that literally thinking "this banana is delicious" does not achieve anything toward the actual delivery of any bananas for consumption. It is the end of the production story, not a part of the process, so it is not abstraction to leave it out. Set up a process for sampling batches of bananas if you want, but the value of that isn't for an employee to think "this banana is delicious" 100 times per day. That is confusing consumption with production. There's a good reason why production doesn't include consumption.
