This is a great response, I agree. One thing I'll add onto point A is that I think it's sometimes impossible to know which side of the 70/30 you're on until the rubber has hit the road and you're deep into implementation. Which of course, complicates the whole thing even further. Take this recent experience of mine - I'm helping someone build a teletech system with Twilio. Nothing too crazy, just connecting customers to a service provider. Seems like the perfect candidate for NCT - heck, even Twilio offers their own in-house NCT (Twilio Studio). I just started building it yesterday and a literal avalanche of questions hit me. What if the call drops? What if the customer isn't happy with the service and wants to speak to someone else? What about (x/y/z) concerns? Before beginning I would have put this project square in the 70%, but now I'm convinced we're in the 30%.
