About DNUG

Since its foundation in 1994, DNUG has established itself on the market – by constant professionally evaluative communication – as a force to be reckoned with and as a competent partner for dialogue. DNUG considers enterprise collaboration as one of the pillars of modern corporate management.

Our mission

The user community’s objective is to promote the best possible utilization of the installed platform. In order to achieve this, DNUG

  • is in close contact and constant communication with the manufacturer
  • facilitates exchange of experiences, knowledge and transfer of know-how
  • organizes conferences and other events
  • operates a networking platform for clients, business partners and universities
  • supports the young collaboration experts by means of the university Initiative

DNUG is committed to the benefit of its members. Therefore, a code of conduct is imposed on all DNUG bodies which takes into account the nonprofit character of the association and prevents abuse.

An essential part of DNUG’s organization is based on the specialist groups founded in 2016. They organize workshops and prepare the contents of the annual conference.

DNUG Domino

The Domino group is mainly concerned with Domino, Notes, Verse On-Premises, Volt and Nomad. We are particularly interested in the “product-specific strategy of the manufacturer HCL” and the “technical administration (installation, configuration, security, performance, etc.)” of the products.

In addition to the internal communication within the section and the entire DNUG, we also offer a dedicated “track” at the annual DNUG conference, a separate “Domino Day” and various webcasts per year to our members and those who will want to provide with the current and important information.
