Why companies are prone to having past problems in new devices? One of the main reasons seems to be the ?weak cognition.? It is usually the result of short term memory, inattention to details, insufficient vigilance, or multitasking. This unsafe work propagates unknowingly because of not engaged or disengaged employees, insufficient understanding of customer needs, splitting design among several designers, and ineffective risk analysis. Another big reason is that ineffective device management procedures often touted as 'best practices', are like a bad virus with long incubation period and no early warning, resulting into sudden catastrophic malfunction of the device. Most companies still hold individuals responsible for mistakes instead of fixing the management process.
Marketing has the advantage of helping prevent past mistakes and improve efficiency of the device design. They have records of customer complaints for years.
