Dedicated intranet system was made in 2013 for the National Museum in Cracow. The purpose of the application is to provide the employees with address base, information about availability of resources (conference rooms, cars, etc.) and base of legal acts, directives and announcements. The system was developed on the basis of precise instructions provided by the Museum. Both the organisational structure of the facility and the expected method of work in the system required individual, dedicated solution. The one proposed by FSi was based both on open components and own functional modules – what allowed for fast execution of the assignment. Moreover, high flexibility of the developed systems allows for future development works – dictated by the changing conditions or expectations of the client.
