3. PHOCUS TUITION CONCEPT 
Fast familiarization and efficient handling are major performance assess- 
ment criteria for a highly functional software product. The development 
of PHOCUS was therefore based on a versatile tuition concept that ensures 
fast and efficient familiarization with the software by different users 
and for different tasks (e. g. data acquisition by operators, project 
management by system managers). 
The overall concept provides for two training areas: 
- Productive use of PHOCUS 
- Application programming in the PHOCUS environment 
This differentiation is required because each area places different 
demands on the users' background. The result is the tuition concept shown 
in Fig. 3. Details on the tuition methods for the productive use of PHOCUS 
are given in section 4.
