This is the second Business Excellence Award for the private company based in Selca, east of Kranj, with the first coming in 2012.
Coming second in this year's selection process was the operator of the Brestanica Gas Thermal Power Plant, which too received the certificate from the European Foundation for Quality Management (EFQM).
The award ceremony in Ljubljana was attended by Economic Development and Technology Minister Zdravko Počivalšek, who said that business excellence should be put in the spotlight, as it was a foundation for competitiveness.
He added that achieving business efficiency and competitiveness was closely related to digital transformation.
"The ministry is establishing a systemic approach supporting companies, with EUR 32 million to be secured through implementing organisations by the end of the current financial perspective," Počivalšek said.
Moreover, the ministry will earmark EUR 12 million for projects aimed at improving the efficiency of operations and sustainable strategic transformation this year.
Ajda Cuderman, the head of the SPIRIT agency, said on the occasion that Slovenia was making progress on international competitiveness rankings, adding that the results could be further improved by introducing business excellence.
Marko Lotrič, the director of the award-winning company, confirmed in a statement for the STA that the business excellence certificate was "key for opening markets".
"This and the fact that we are a family company are the important reasons why business partners pick us," he said, adding that achieving business excellence was a matter of changes in many fields, including leadership and strategies.
Last year, the Business Excellence Award went to the British-owned car industry supplier GKN Driveline Slovenija, following two years during which the award was not conferred.
