Ideal Actuarial System

An ideal actuarial processing solution is a a) transparent to users and b) highly efficient storage/retrieval system for c) structured actuarial data (objects) with d) an extremely flexible, e) computationally complete, f) open calculation engine and g) integrated, h) automated and i) interactivereport generator

Actuarially-Centric Systems

Insurance companies build their computer systems around their strengths: Claims Accounting Underwriting

Actuarial Functionality is always an afterthought 2a

Human perception

Relies heavily on Short-Term Memory.Problems with STM: Can hold only 5-7 similar similar items at

once It’s a “buffer”: new info erases old

information Even without distractions can hold info only

for 30 seconds 2b

Adaptive Reporting: Filtering

3

Auto-Filter in Excel Plain-Vanilla Filtering Checking Distinct Values Adaptive Filtering (through VBA)

Adaptive Reporting: Outlining

4

Outlining in Excel Hierarchical view Different level of details Subtotals

Master-Detail relationship in Access

Adaptive Reporting: Sorting

5

Does not reduce amount of information displayed

Brings most important info on top or up front

Requires definition of importance

Adaptive Reporting: Dynamic Formatting

6

Conditional Formatting in Excel allows users to define

font color border background pattern

of a cell as a function of the values in other cells

Adaptive Reporting: OLAP(Online Analitycal Processing)

Visualization: Charts

There is a chart for every occasion: line chart for displaying increases bar for shares pedestal for ranks Gantt for schedules

But what about actuarial triangles?

Visualization: Animation

10

If a picture is worth a thousand words, thenan animation is worth a thousand pictures “selective attention”: people react on any

movement (change in color, shape or position) display of different stages in the motion displacement plots time animations streamlines (traces)

For actuaries: iterations of simulation!

Visualization: Visual Tools

11

Making actuarial selections interactively, directly on the chart

Instant visual feedback Changing parameters during animation:

invaluable for DFA

Alarm Systems: Data Quality

Alarm System triggers an action whenever problem is found: creates record in the log sends e-mail stops processing runs additional tests

Dashboard’s space limitations re-emphasize the necessity of space-conscious reporting techniques!

Conclusion

15

For effective use of computerized reporting tools available to actuaries, it is imperative to define measurable indicators of actuarial significance…
