Engineers often work with marketing, sales, and perhaps a creative department when recommending packaging requirement for a product. Good packaging must protect the product, eliminate any damage while moving, shipping, or storing the products, and also make the product attractive if it is to be displayed in a consumer environment such as a grocery store, hardware store, or department store. For this reason, packaging is a critical part of a product's design and engineering process, and engineers must take many factors into consideration including appearance, function, and costs.
Engineers have to consider the durability, cost, and performance of different materials when designing products and the package they will ship or be displayed in. Many factors will help determine which materials to use, such as how long the package will be on the product, how fragile or expensive the product is, and whether exposure to temperature or humidity would impact the performance of the product.
The following three measurements must be made for each incoming package:
Determine the overall score for each package to determine the top scoring "engineering team." Use the following equation:
Overall Score = Intactness score (c) / [mass in Kg (a) x volume in cc (b)]
Example: a. mass = 0.145 kg b. volume = 240 cc c. intactness score = 100
Overall Score: (c) 100 / [(a) 0.145 kg x (b) 240 cc] = 2.87
