The device itself is complex, but it doesn't operate in a vacuum. To deliver maximum value, such thermostats are being integrated into larger smart home control systems - which may or may not be produced by Nest. Therefore, it must operate not only as a stand-alone system made up of complex subsystems but be capable of operating within a much larger "system of systems," from a smart home system to a smart local electrical grid system, to a smart regional, national or continental electrical grid system.
Strategies for addressing such dependencies and complexities are the domain of systems engineering, a collaborative, interdisciplinary approach to designing, realizing and managing complex systems that interact to produce behavior no individual element of the system can (see "Mind-Boggling Complexity"). The challenge becomes even bigger when these complex systems become part of the largest system of systems ever created: an ultra-large-scale system (ULSS) known as the IoT, which will incorporate devices from hundreds of thousands of makers, all with differing - even conflicting - objectives and approaches.
As organisations work through the complex business of mastering and making complexity disappear - a critical element of a positive experience - what is most important, Pine believes, is to "keep the customer at the center of their thinking, and to remember they are not producing things for an Internet of Things, but creating living, evolving experiences within an Internet of Experiences."
Back in Melbourne, Green Leaf Elm, Tree ID 1022165 and citizen "F" are building a relationship that honors this distinction. Once upon a time, "F" might have simply walked by Tree 1022165. But now, Tree 1022165 and "F" are connected. As "F" writes, "we don't have a lot in common, you being a tree and such. But I'm glad we're in this together."
