Control is the mate of Planning, another area that strong actuarial help is valuable. Control gets a bad rap from people that feel that the term implies heavy-handed oversight or punitive measures, but is, in reality, an essential part of the planning process. Where planning says what you are going to do and when, control checks on those plans and can suggest corrective action when plans are going awry, as they so often do.
There are three types of control processes - (1) Feedback Control, (2) Concurrent Control, and (3) Feed-Forward Control.
Feedback Control is frequently done by actuaries in insurance companies. Studies of rate levels, unallocated expense allocation, projected expenses, loss reserve calculations are often purely or nearly purely Feedback Control, in that they base the future projections on historical results. In project management, Feedback Control is considered the least optimal control method, since the undesirable events have already occurred well before the control function is initialized. Interestingly, projections based on historical events is quite favored by insurance departments of insurance, that frequently require explanation if your projections are based on anything else.
Concurrent Control is a type of control that takes place when a process is about to occur. The final checking before sending rate filings, Annual Statement reports, agent's bonuses, large claim settlement reports, etc. are are form of Concurrent Control. Training and periodic checking of employee work is also considered Concurrent Control.
The last form of control is an interesting one. It is a form of control more and more actuaries are getting involved in. This type of control function is called Feed-Forward Control and it's goal is to inspire corrective action before a deviation in the plan occurs. Actuaries call it "modeling" and have applied the concept to forecasts of future profitability, premium levels, claim costs for certain lines of business, enterprise risk management, or dynamic financial analysis.
The steps of Feed-Forward Control are as follows:
- Identify all relevant input variables. For project management, these variables relate to time, volume, and money (or costs of the project). For actuarial work for insurance companies, the variables might be premiums, loss costs, expenses, investment income, risks of various company functions or operations, etc.
- Build a dynamic model representing the process and keep it updated.
- Collect data and enter into your model. For most projects I do, the data gets collected into the model before, during, and after it is built.
- Perform regular assessment of the projected path and the variation from the plan. Are the loss costs out of range? Is persistency decreasing off planned values? Is the level of risk for a type of insured/coverage/policy unacceptably high? Are the number of claims or policies off plan?
- Take action - Feed-Forward Control provides the early warning system needed to take action before getting too far away from plan.
