14. 10-14 Copyright © Oracle Corporation, 2005. All rights reserved. Business Understanding Level 1 Discovery Governance Applications Business Organization Technology

15. 10-15 Copyright © Oracle Corporation, 2005. All rights reserved. Business Depth Level 2 Discovery Seek more detail in specific areas Focus where customer indicates need Probes should target… –Specific business processes (inefficiencies, inconsistencies, errors, costly, slow, manual) –Interaction and process support for constituents (multichannel) –Specific applications (gaps and deficiencies in support for processes) –Overlapping or duplicate process and support –Lack of visibility into operational areas –Low productivity [lack of automation], redundant tasks –IT complexity (many technologies/skillsets, app to app integration) –Applications not aligned with business needs

16. 10-16 Copyright © Oracle Corporation, 2005. All rights reserved. Level 2 Discovery Examples “Tell me more about the __________ process.” “What should I know about the ______ application.” “What is important about ______________.” “What is your perspective on ______________.”

17. 10-17 Copyright © Oracle Corporation, 2005. All rights reserved. Workshop Business Case Level 2 discovery “What should I know about Scan-Based Trading and Greenfield Nurseries?” “Without an effective Scan-Based Trading solution, we will no longer be able to do business with Home Depot. We need to use our current applications and overlay them with SBT capability.” Asset reuse, Scalabilit y, Business responsiveness “We must quickly rollout a solution to trial locations and expand support to nationwide within 6 months.”

18. 10-18 Copyright © Oracle Corporation, 2005. All rights reserved. Workshop Business Case Level 2 discovery “You said SBT is largely about inventory management? How are your inventory management processes and applications affected by the new business model?” “We need a clear picture of store level inventory… Without accurate information on store inventory, product shelves will be empty. That means we are losing business.” Improve operationa l visibility, “As far inventory applications, we have 3. We plan to consolidate. For now they are all important and support different geographies.” Appl isolation, retirement

19. 10-19 Copyright © Oracle Corporation, 2005. All rights reserved. Workshop Business Case Level 2 discovery “So an accurate view of store inventory is important. Tell me how you use that information” “Store inventory is important to guide the replenishment process. Today, our reps review the inventory, create a sales order and fax that to the office at a later time. Improve process efficiency This is slow and we sometimes create errors keying in the orders. The errors often go undetected for a long period”

20. 10-20 Copyright © Oracle Corporation, 2005. All rights reserved. Workshop Business Case Level 2 discovery “Your current focus for Scan-Based Trading is Home Depot. What do you expect from other retailers?” “We also must plan for supporting Scan-Based Trading with other retailers. Home Depot is the first but we expect other retailers to follow soon. We need a process to quickly provide SBT support for others, with special processing rules for each retailer.” Process flexibility Adaptable business rules

21. 10-21 Copyright © Oracle Corporation, 2005. All rights reserved. Workshop Business Case Level 2 discovery “So you need to support new retailers quickly once they initiate SBT for their suppliers. How would you respond to such requests today?” “No. We typically can’t change our systems fast enough. The business will pull together some manual processes to support each new retailer while IT works on application changes.” Reduce business-IT gap “Once the IT systems are modified, we’ll drop the manual efforts.”

22. 10-22 Copyright © Oracle Corporation, 2005. All rights reserved. Technology Understanding Level 3 Discovery Seek “under the covers” technology understanding Technology to applications mapping Build and deployment architectures –Java,.NET, ‘C’ –Messaging (JMS, MQ, Custom sockets, etc.) –Hardware, Operating systems –Databases –Custom, Third-Party applications

23. 10-23 Copyright © Oracle Corporation, 2005. All rights reserved.
