Answer: efficient communication between engineers and teams
Explanation: Concurrent engineering concept or design is a strategy where all the tasks involved in product development are done in parallel. It is an approach used in product development in which all functions are integrated to reduce the time required to bring a new product to market.
One of the major challenges engineering managers face here is effective and efficient communication. To start with, every member of the team must know the design goals/objectives and must be aware of the interrelationships between all aspects of the design process, therefore there is need for superior communication between all sections of the company.
There are now service providers who not only train people on how to perform concurrent design effectively, but also provide the necessary tools to enhance communication between the team members.
