This section of TIMG 5103 (Advanced Topics in TIM) is an in-depth exploration of platforms, communities, and business ecosystems, and the real-world field settings that bundle these subsystems together.  More specifically, we examine the design and architecture of the multilevel field settings where organizations and individuals come together to achieve system-level outcomes that no participant could feasibly achieve by working alone. This is an active area of research within the TIM program.
