Question $4(70$ pts$.)$:

Consider the process: build robot swarm. This process can be divided into four steps: Design Swarm, Purchase Parts, Assemble Robots, Test Swarm.

The step Design Swarm takes as an input the needs analysis and requirements documents generated by the design team. The design process is conducted per document BID$4$R$\mathrm{.}1\mathrm{.}2.$ The design step is conducted by the design team. The output of this process is a parts list, blueprints, and testing procedures.

The step Purchase Parts takes as an input the parts list. Purchasing occurs as directed by BID$4$R procedures and PPAMP. The design team uses a P$-$card for the purchases. At the end of this step the team receives the raw materials.

The step Assemble Robots requires the raw materials. The blueprints are used to guide the assembly. The design team uses a screwdriver for assembly. The end result is completed robots.

Finally, Test Swarm requires the completed robots. Testing is conducted in accordance with the testing procedures and BID$4$R procedures. To conduct testing requires the Swarm Test Platform. The result of testing is validated robots.

Develop an IDEF$0$ model for this process.
