Final answer:
The statement D) Development team must agree on product characteristics early in the development process pertains more to a sequential development process because it requires early decision-making and follows a strictly ordered set of stages without overlap.
Step-by-step explanation:
The statement that pertains more to a sequential development process rather than a concurrent development process is D) Development team must agree on product characteristics early in the development process.
In a sequential development process, each phase of product development occurs in order, one after the other, without overlapping. This necessitates that the team makes decisions about product characteristics early on, as changes in later stages can be costly and time-consuming. Therefore, once a detailed design is chosen, the development team moves forward with prototyping, testing, and refinement, taking care not to cycle back to earlier stages unless absolutely necessary.
In contrast, a concurrent or spiral development process involves overlapping phases, where different stages such as design, development, and testing occur simultaneously. This allows for more iterative and flexible product development, where feedback from the testing phase can influence design changes on the fly.
