Overcoming the language barrier

Answer
If top management is interested in the implementation of a quality management system (QMS), it is because there are some kind of benefits for the organization.

My advice is translating those benefits into practical positive consequences for middle management persons like:

Implementing a QMS -Certifying the QMS -More international credibility -More orders -More production -Higher wages

Implementing a QMS -Less quality problems -More efficiency -Less costs -More production and competitiveness -Higher wages -Higher status

If language is a barrier use simple messages, tell them a story, make them play a game, something that pass the message.
