Well, ideally, nobody should cross his/her lines unless it is absolutely necessary. That is why specializations in knowledge and expertise are for, right? Well, in many cases, this crossing of line is necessary.
No wonder why it is easier for Toyota users to change spark plugs than for the users of Chevy. No wonder why the strong packaging by Meridian chips sometimes leads to difficulty in opening the pack when compared to opening the pack of Lays. In many cases, better quality from engineering point of view may lead to a “poor” quality at user level. It is all about user friendliness and perception. Many manufacturing companies do involve marketing experts at the “design” phase of their brands. This crossing of line is absolutely necessary. In fact, it should not be thought of as there exists a line in between! Design inputs by brand experts must be an integral part of manufacturing process. After all, it is the customer that matters.
