Device or product owners do not have a good image of what they want to refine in certain instances. The incentive function is always multidimensional and involves different sub-goals to be balanced. Another great insight here which reminds me of machine latency discussions) is that ‘normal performance’ (i.e. expectation) is always an inadequate measure, and for all task instances, the system needs to perform well.
