Main ideas & concepts

Centralized data processing
- Data processing is handled in one (or a few) large computers/servers located in a central site.
- Designed to serve the needs of the entire organization.
Distributed data processing
- Data processing is arranged so that centralization is carried out in each business unit.
- Processing can be handled by the units themselves under their own control.
- Each full functional area has its own information services unit.

In practice, companies typically fall between two extremes:
- “All-centralized” and “fully distributed.”
When systems are distributed, there’s often a tendency toward a “distributed processing system” structure (the lesson emphasizes flexibility, but with management tradeoffs).

Lower costs
- Possible cost reduction for hardware procurement.
- Reduced costs for data entry.
Better cost control
- Enables process improvements that support controlling expenses.
Higher user satisfaction
- Because processing is closer to users and under user/unit control.
Better data backup and resilience
- Data storage in multiple places creates backups.
- If data in one location is lost/damaged, it may not affect other locations as severely.

Loss of centralized control
- Each unit may develop systems according to its own wishes, which can lead to fragmentation.
Compatibility problems
- Systems developed by different units may not be compatible with one another.
Mismanagement risk
- Potential incompatibility and coordination problems can increase risk in managing hardware/software resources.
Data consolidation difficulties
- Data stored/processed in different units may need to be merged, creating complexity.
Difficulty obtaining/maintaining qualified personnel
- Recruiting people who can manage the system properly can be hard.
Standardization procurement challenges
- Applying consistent standards for acquiring accounting information resources/systems can be difficult.

Accountants are not only users; they can also become:
- Developers/designers
- Auditors (with specific audit roles)
A key expectation:
- Accountants must be able to clearly communicate information needs to system professionals.
- They should actively participate during system development to ensure the system meets real accounting needs.

Accountant as a developer/design participant
- Formulating the conceptual system
  - Determine:
    - Nature of information needed
    - Sources of information
    - Purpose / users of the information
    - Accounting standards/rules that must be applied
Accountant as an “editor” / assurance participant
- Three stated possibilities:
  1. External auditor
    - Assesses the fairness of financial reports and may provide other assurance services.
  2. Auditor-accountant for computer system evaluation
    - Evaluates computer systems (often as part of an external audit).
  3. Internal auditor
    - Conducts audits/evaluations of the organization’s information system.
