Based on the task guide presented, it is important that each department participates
in the responsibility of the product’s development. Each must do their share of the work for the program to be successful. This implies the use of checklists, procedures, and a repetitive and/or specifi ed method for doing their job to ensure no item is left undone or forgotten.

In a typical custom Injection Molder, there may be only one employee to cover several departments and operations, which is a stronger case for the use of checklists. The benefi t from this is that the employees are more knowledgeable in more areas than an employee in a tightly controlled department in a larger company. Know more, do more, and forget/omit less is the key to this operation.

Often, the supplier is invited to participate in the development of the customer’s product. This gives the supplier a strong area in which their knowledge and experience can affect the performance and quality of the product. By being proactive in working with the customer, they can infl uence the product’s design, and type of mold, while adding value with the molded – in – part functions to give them advantages over their competition.

Too often in large companies when work is completed by one department and transferred to another, the objective of the product and what was done earlier to facilitate quality or savings may get lost in the transfer. This is why at the start of a program, the product ’ s end – use objectives are documented, and all additions to the program are also documented. The manager travels with the documentation to ensure everyone is knowledgeable and the product will meet these objectives.

This product requirement list travels with the documentation, is reviewed by each department involved, and is considered for improvements at each step of the development process. As each item is met, it can be crossed off as completed. Should new ideas infl uence the product ’ s development, which includes manufacture, tooling, Injection Molding, assembly, and decoration, the item is documented on the product manufacturing documentation. Affected personnel are notifi ed, and the revised item is reviewed for incorporation into the program. If a material change is considered for the product, now is the time to do it, not after the mold cavity is sized. Also, under consideration is the end – use environment the part must endure. All of these and more items must be explored. The Design and Development Checklist number 3 in Appendix C is mandatory to avoid overlooking an important item during the initial design phase.
