Todd Orr, Duke UniversityNeal Wormsley, University of Tennessee

Session Code: 2204

Duke University Background

• Duke University & Duke University Health System– $2.2 billion in revenue– 30,000 employees– DUHS composed of 3 hospitals, physician practices,

hospice, and other health related entities

• In production with FI/CO/MM/FM/PS/AM since March 1999– Initial focus on Health System; 1,800 current users– Rollout of financials to University in next two years

• Implementing SAP HR/Payroll - go live by end of 2001

If We Have R/3, Why DSS?

• Difference between OLTP and OLAP– OLTP: On Line Transaction Processing

- R/3– OLAP: On Line Analytical Processing -

DSS

• DSS/OLAP allows us to leverage the investment in R/3

• Existing Duke experience with query/OLAP tools

Role of Decision Support at Duke• Decision Support (DSS) key component of

our original design for R/3 strategy because:– Lack of easy-to-use query and reporting tools in

R/3– Problems associated with running reports &

queries against the production database– Limited accessibility of R/3 for query & reporting

• DSS planned to provide financial, procurement and HR/Payroll data

• DSS for Duke is not data warehousing

Duke DSS Tool Environment• Investigated ETL tools

Why not BW?

• Duke reviewed BW in 1999 when it was at version 1.2; first version left a lot to be desired

• Existing investment in other OLAP tools (Essbase)

• Level of overhead associated with BW implementation

• BW in context of larger data warehouse strategy at Duke

• Door is still open

DSS Current Status

• Financial DSS was completed this month– Series of Oracle tables/views– Summarized actuals/budgets at the Fund-

Commitment Item-Fiscal Period-Fiscal Year level– Source for extracts to front-end tools (Essbase)– Directly accessible with query tools

• Procurement DSS– Requirements analysis underway– Will be looking at front-end tools

• HR/Payroll DSS - need to go live first
