This paper presents the evaluation strategy and the first results we obtained when we used the FACTS4WORKERS evaluation framework. The purpose of the framework is to prove whether the project interventions achieve the expected results, which are: improving workers’ job satisfaction, increasing innovation and problem solving skills as well as enhancing productivity. Because of the diversity of the industrial partners and of the workplaces where the interventions are going to be implemented, the different languages, legal and cultural environments the framework was conceived as general as possible to be adapted to any particular case. We present here one example for using the framework, the first results of these measurements and the feedback the evaluation provides both for supporting the decisions about the interventions and about the framework itself
