How to thoroughly improve the process of organizing exhibitions in a cultural institution? Is project management in a museum possible? How to implement new tools? What to do after initiating a change? This article provides answers to these questions through a case study prepared by the Head of the Exhibition Organization Department and the Head of the Coordinators Section of the National Museum in Krakow, directly responsible for the exhibition organization process. The article describes the events from 2016 to 2019. This includes an audit of the existing process of exhibition organization, implementation of corrective measures, introduction of new tools, their updating and verification, taking into account such solutions as treating the exhibition as a project, PRINCE2 and Scrum methods, a detailed description of the process, and creating standardized templates of project documents, i.e. a list of objects, project charter, project schedule, partial schedule, project budget, evaluation. These activities resulted in the improvement of team cooperation, the elimination of avoidable delays, the automation and acceleration of the process of preparing project documentation, making the obligations of individual team members public, submitting project data to the stakeholders of a given project on an ongoing basis, reducing the amount of manual work, and reducing the cost of the implementation of individual projects.
