*4.3. Develop an Interim Containment Action (D3)*

Both interim and rapid interventions were implemented to solve most of the six problems, including those concerning inverted cables, disfigured motors, lack of ID tag, and wrong cable length. A series of interim visual aids were developed to help employees assemble the components. Regarding inverted cables and disfigured motors, a document is created to report the conditions of both the stepper motor and the cables before and after being handled by the employee. Additionally, as Figure 6 presents, a provisional sign is created for helping employees to insert the assembly cables not only in the correct positions, but also in the right entry holes by using the colors of the cables as references. Similarly, the sign is intended to help employees guarantee that each cable's final end is the one that is required by customers.

Finally, AutoCAD® was used to design a customizable 1:1 scale 2D template of a drawing provided by customers for the assemblies to verify that customers' demands would be accomplished, as shown in Figure 7. Perhaps the greatest advantage of this electronic template is that it can be stored in a database and updated for new specifications (i.e., new cable length) if required. The updates can be performed quickly and effectively without compromising the template function. After implementing this system of solutions (i.e., the spreadsheet, the sign, and the 2D template), it was noticed that the most insignificant errors were immediately fixed; consequently, four of the six problems were solved. In order to confirm this, a quality inspector assessed the assemblies and later confirmed that the problems had been successfully solved.
