A process plan will include a list of necessary steps, necessary tools, and the _____ needed to complete each step:

A process plan is a detailed outline that guides the execution of tasks in a manufacturing or production environment. It typically includes a breakdown of necessary steps to be taken, the tools required for each step, and the materials that are essential for accomplishing the task.

Including materials in the process plan is critical because it specifies what substances or components are required at each stage of production. This ensures that the necessary resources are available when needed, which helps in preventing delays and optimizing workflow. By identifying the materials upfront, the team can better plan their procurement and ensure that all inputs align with the production schedule.

The other factors, while important in their own right, serve different functions: personnel assignments detail who is responsible for each step, specifications define the quality and technical parameters of the output, and timelines establish the duration for each step but do not directly relate to the physical inputs required for the process.
