The paper presents programs dedicated to computerised maintenance management systems (CMMS). The main aims of the programs are: effective maintenance of machines, rational asset management, and consequently higher productivity of a company. The programs can be dedicated to particular industry sectors or can be more general, but they contain similar modules. One can find the lists of: assets, resources, preventive maintenance jobs, breakdowns, massages, and documents. The programs can be treated as database systems and messenger programs which aid the analyses of data and exchange of information among staff.
