Five Software Packages

Technis' five software packages include the unique FARADIP.FOUR reliability data base, developed by David for over 30 years and now widely used for risk and reliability work for both mechanical and electrical equipment.


The Technis guidelines have been developed over a number of years whilst carrying out numerous reliability and functional safety assessments. They contain a combination of "best practice" and "actual data" collected by Technis. They are updated from time to time as information becomes available. They currently consist of 12 Technis Documents.
