Pega Extended Support program

For Chordiant applications, Extended Support is limited to screen-sharing or on-site support (if needed). In addition, Pega does not have the ability to create patches or hotfixes and cannot guarantee a resolution in all circumstances. If we are unable to resolve the issue via screen-share, it may necessitate going on-site to assist in devising a possible workaround. Client is responsible for Pega travel expenses for any on-site support.

Please contact your account team to discuss how Pega can help you achieve your business needs with our latest product offerings.
