How many times have you asked this question--to your peers, to important customers, during strategy meetings. It is an effective way of cutting through the noise to uncover the essence of key care-abouts.
I've been thinking about that from an industrial automation perspective. The industry itself is nearing 45+ years, beginning with the development of the PLC (Programmable Logic Controller) back in the 70's. Their key care-abouts at the time were to replace unstable and single purpose relays with a device that could multi-task different plant control functions, that could be programmed in a language that the plant electrician could understand, and could more effectively manage multitudes of control sensors.
