For quality management, we generated our own quality assurance
system by the name of DOQUM. It determines data according to a
room area index, specifications, job descriptions and complaints,
and helps us ensure long-term quality at the agreed level.
In the catering area, we have programmed a DOQUM version
coordinated with the workflows and quality requirements
of commercial kitchens. It can be individually adapted to any business
situation. Even the hygiene management points and critical
controls required by the HACCP concept (Hazard Analysis
Control Point) are integrated in the DOQUM system. DOQUM is
also the only system in the industry that is certified according to
DIN EN 13549.
In the building management area, we use CAFM (Computer Aided
Facility Management), which lets us create a networked building.
This enables more efficient maintenance, improved and perfectly
customized cleaning as well as a better overview of actually
services. It also leads to higher efficiency and longterm
rationell reinigen: How is digitization used in building cleaning?
Harald Griebel: In this sector, the so-called IoT (Internet of Things)
has long played an important role. An example of this is the intelligent
washroom. Specially programmed sensors report soap
that must be refilled. In addition, tablets let users note
their degree of satisfaction about restroom cleanliness.
rationell reinigen: How can building service providers benefit
Harald Griebel: Internal networks and automated workflows
ensure improved cleaning quality by informing us in real-time
about the degree of soiling.
rationell reinigen: What do you see as the greatest challenges
Harald Griebel: One of the greatest challenges for building service
providers like us is certainly keeping up-to-date and constantly
adapting our business models. Otherwise, you can quickly lose
pace with the newest developments in the digital world.
A further challenge is standardizing systems while still remaining
as flexible as possible. Customer requirements are different.
At Dorfner, we always respond to the individual needs of our
We must thus create flexible systems that can adapt to
the often rigid IT environments.
rationell reinigen: Digitization is accelerating at maximum speed.
What could this mean for the future of building cleaning services
or its providers’ business areas?
Harald Griebel: There are no limits to the imagination here. For
quite some time, we have had a type of “InnovationLab” at our
company. Our goal is to rethink the future of our business sector
without any taboos. In addition, we try new things out that we
For example, we are currently at the starting block with so-called
Mixed Reality goggles – which will take us to the next step of
digitization. These classes let us digitally measure rooms and
directly prepare and call up information on technical data, piping
or maintenance history. The technician then sees this information
in real time. Sensors connected with the goggles enable immediate
This allows the status of systems and system parts to be constantly
monitored. It makes repair and maintenance more efficient
because they can be carried out exactly when necessary. The
result is proactive repair and increased productivity. Aided by
the reported data, the Facility Manager can also easily determine
changed user behavior and take direct action.
rationell reinigen: In regard to data, data protection is very
important in Germany. With the advances in digitization, how can
the personal data of employees, customers and building service
providers be protected?
Harald Griebel: Germany has one of the most ambitious data protection
laws of all. We strictly comply with all of these regulations.
In addition, our data protection officer also pays close attention
to compliance. But we are entirely aware how sensitive we must
remain. In addition to the legal component, data protection always
has an emotional component. The greatest possible transparency
towards our employees and customers is the best method of
rationell reinigen: What does technological progress mean for
employees who are constantly faced with new demands?
Harald Griebel: We are responsible that our employees are not
left behind. It cannot be avoided, however, that these advances are
harder for some employees than for others. Altogether, everyone
has to make themselves fit for digital progress. One action we
have taken in this regard is creating our in-house Hans-Dorfner
rationell reinigen: Will people be eventually replaced by the
increasingly mature technologies?
Harald Griebel: No, definitely not. People are and will remain
indispensable because they are the ones who make buildings
in the first place. They are, so to speak, the intersection
between technology and buildings. Intelligent technologies and
tools are meant to facilitate and improve work as well as offer our
employees and our customers added value.

about your company. N
