I think clause 5.5.3 Internal communication requirement are so weak in ISO 9001 and TS 16949 standards. Communication is one of the biggest problem for lots of compaines but i never saw that an auditor stuck on this requirement. An effective management system already has to supply good communication for everey processes. In that case 5.5.3 is an unnecessary clause with the current situation or it has to be more clarified and detailed or they have to find a way to measure effectiveness of the communication. Every company use e-mail, phone, meetings, communication boards. So ? What is the difference between a certified company and non-certified company ? Is there any best practice in your company ? What is your opinion ?
