Examples of Information Systems Supporting the Functional Areas

Functional Area Information Systems Reports

Routine reports Ad hoc (on demand) reports

Drill-down reports Key-indicator reports Comparative reports

Exception reports

Summary Report

A summary report is one type of routine report

Detailed Report

A detailed report is another type of routine report

Drill-Down Report

8.4 Customer Relationship Management Includes a one-to-one

relationship between a customer and a seller.

One simple idea “Treat different customers differently.”

Helps keep profitable customers and maximizes lifetime revenue from them.

The Need for CRM

It costs six times more to sell to a new customer than to sell to an existing one.

A typical dissatisfied customer will tell 8-10 people.

By increasing the customer retention rate by 5%, profits could increase by 85%.

Odds of selling to new customers = 15%, compared to the odds of selling to existing customers (50%)

70% of complaining customers will remain loyal if problem is solved

Problems stem mainly from two sources: Uncertainties due to demand forecast, delivery

times, quality problems in materials and parts that can create production delays;

Cultural differences Localization Economic and Political Differences Legal issues Cross-border data transfer which refers to the

flow of corporate data across nations’ borders.
