Michigan's EDW has almost 10,000 users in five major departments, 20 agencies, and more than 100 bureaus. Just in the Department of Human Services, the EDW contributes to nearly every function, including accurate delivery of and accounting for benefits to almost 2.5 million clients receiving public assistance. It is safe to say that the EDW was large and complex.

2. What are the size and complexity of EDW used by state agencies in Michigan?

The challenge is not directly stated, but students should be aware that state governments struggle to balance budgets and satisfy a wide variety of needs. They also should recognize that a state operates many kinds of departments, so it likely could benefit from a unified source of information. The proposed solution was an enterprise (statewide) electronic data warehouse linking employees across departments. The obtained results include financial benefits worth $1 million per business day. Savings come from operational efficiencies, avoidance of sanctions, improved client outcomes, integrity benefits awarded to well-performing programs, and recovery of inappropriate benefits payments. The data warehouse has yielded a 15:1 cost-effectiveness ratio and improvements in the accurate delivery and accounting of benefits.

Because the customer experience is critical, all customer issues need to be tracked, monitored, and resolved as quickly as possible. But Expedia had no uniform way of measuring satisfaction, of analyzing the drivers of satisfaction, or of determining the impact of satisfaction on the company's profitability or overall business objectives. However, there was plenty of data to work with. It took a business analyst two to three weeks every month to pull and aggregate the data, leaving virtually no time for analysis. Expedia's solution was to start by identifying key drivers of customer satisfaction. From these drivers, the customer satisfaction group constructed a scorecard application. They came up with 10 to 12 objectives that linked directly to Expedia's corporate initiatives, which translated into more than 200 KPIs. This involved three steps: deciding how to measure satisfaction, setting performance targets, and putting the data into context. All of this was applied to their data warehouse (which they called DSS Factory). As a result, managers and executives have a quick and transparent view of how well actions are aligning with the strategy, with the ability to drill down into the data underlying any of the trends or patterns observed. This would have taken weeks to do previously. Other business units are also benefitting.

What were the challenges, the proposed solution, and the obtained results of Expedia.com?
