Why M3 Checklists? In this chapter, extensive checklists of processes, sources, software, networks, and solution providers are covered in detail to ensure machine-to-machine marketing (M3) marketers execute successful anonymous advertising apps anywhere anytime (A5) campaigns. Why checklists? Because they are a type of informational job aid used to reduce failure by compensating for potential limits of M3 marketers’ memory, attention, and the discipline to focus on their A5 tasks and strategies.
