You have been hired by Professor Myers who is tired and frustrated with the markers and pens falling down between the fixed whiteboard and front wall in his classroom. The classroom has 3 whiteboards on the left side and 3 whiteboards on the right side (pictures in attachment below). These 3 whiteboards on each side are stacked one in front of the other. While the back whiteboard is fixed, the 2 in front can slide up and down. When both sliding whiteboards are raised, there is a gap of 4.5 inches between the marker tray and the fixed back whiteboard. Several markers and erasers are accidently dropped into this gap each semester disrupting the class, especially when there are no other markers or erasers available. Apply the concepts of Poka Yoke to mistake proof the board and markers/pens. Submit a 2 page writeup on potential Poka Yoke devices to mistake-proof this issue. Your intro should include a brief discussion of Poka Yoke. You should offer multiple solutions including a cost/time/savings estimate for each solution as well as classifying each solution
