Z-Coach is for getting coaching in areas like:

• Adding more customizations to an existing ChangeMan ZMF implementation, e.g. because of new business requirements or because of additional applications being added to ChangeMan ZMF.
• Upgrading to a new release of ChangeMan ZMF.
• Keeping an old (no longer supported by SERENA) release of ChangeMan ZMF up and running, e.g. for issues like this one.
• Providing technical support to ChangeMan ZMF customers that are out of SERENA support (no longer current on M&E).
• Setting up an ITIL compliant ChangeMan ZMF helpdesk.

Using this approach, we coach/assist/teach you so that you can complete such activities, whereas with Z-Act we take care of all such activities (we perform them for you).
