Factors of Influence for Accounting
Technical View
To get with a minimum
of hardware a maximum
of throughput.
Premise:
Total Workload,
Total I/Os
Commercial View
Business economist:
operational evaluation
Hardware:
> VALUE <
Applications:
Ranking 1 - 100
Efficiency of the different
projects / departments in
comparison to the total IT costs

What is a business process ?
You need:
Condition variables to correlate
different geographic locations
regarding applics., users
(Transactions belong to a specific

Example: SAP R/3
Dialog steps 1-n --> Transaction -->
BP: Finance

Accounting as a Starting Point

Basic Reflections
- "start small"
- Charging for amount of data (network load) or
user oriented
- Data collection
- Aggregation (Reduce)
- Duplicate data checking (automatic DB-Management)
- Representation of the company structure
- Price definition for different units
- Effort of implementation
