Part Development
Part development typically refers to all of the stages involved in bringing a product from concept or idea through market release and beyond. In other words, part development incorporates a product’s entire journey.
There are many steps to this process but it’s not the same path for every organization. Before too much time is spent prototyping and design, whether the proposed solution is viable should be tested. This can still happen at the conceptual level. Still, it is an early test to see whether the particular part is worth pursuing further or if it will be rejected or only lightly adopted by the target user.
