Final answer:
The statement is true; not all new-product projects by major companies reach commercialization due to various challenges such as costs and market viability.
Step-by-step explanation:
The statement 'True or false: Majority rule can fail to produce a single preferred outcome when there are more than two choices' is true. This phenomenon is often seen in the context of new-product development where the generation of ideas is high, but not all progress to the commercialization stage. Many companies initiate a large number of new-product projects, but only a few make it to market due to various reasons such as market viability, development costs, and competitive environment. This pathway from concept to market is often fraught with evaluations, revisions, and strict go/no-go decisions, which are difficult to navigate. As a result, the majority of new-product projects do not achieve commercialization.
