Do you agree that Customer Relationship Management (CRM) entails all interaction that a company has with its customer, be it in sales or a service?

CRM is an excellent sales and data tool to be used within any company. The only way to retain customers, especially if their is major staff turnover. Its user friendly and all relevant customer details are available, whether it is good or bad.... It should be utilised right through the orginisation.

Yes sure!

Customer Relationship Management (CRM) is very important, it built this very good in business called customer loyalty

Sadly, it seems that most companies, management and staff are missing the point when it comes to CRM and Big Data. My answer to such question is posted in my architect for CRM and Big data site " http://crmdatafarm.com/" under the following pages:

I am hoping that I can team up with companies or investors and make my architect a reality.

Yes, CRM, both as a software and management strategy entails all interactions customers.

That's why most modern CRM software (and policy papers) include modules (divisions) on sales force automation related to sales escalation form lead to customer/opportunity to proposal to invoice etc.

Also, they contain modules for customer support and service with support ticket management & a knowledge base module to educate (new) employees about policies/standards/solutions.
