1. Topic 1: Event Processing Scope, Classification and Business Value Udo, Darko, Mani, Roy, Robert 18 May, 2010

2. Agenda/Deliverables Stakeholder identification – Who are they – What stake do they have – How to answer the “Why” questions for each Key Questions – Clarify – Answer Long term objectives – Identify and refine

3. Questions Scope – What problems does Event Processing Solve? What forms do Event Processing Applications Take? Business Value – What particular values does an Event Processing approach bring? – How can we measure these values? What are the key factors? – What will this new market require to be viable? (e.g., education?)

4. What problems does Event Processing Solve? Stakeholder: Industry Event Processing has been with us from the beginning of time Our approach today was to focus on one key class of problems: Situational Awareness and Response – There is a high volume of events representing accumulating, incremental state change with – a need to effect timely action: must have the potential to respond immediately. – Systems under control/observation is Event Driven – Event data could be made available from the real world in electronic form – There is a continuous evolution of requirements (e.g., new event sources/types; new response opportunities;...)

5. Questions Shall I solve the problem with EP or some other available technology and architecture? How expensive and effective is a solution based on EP? Can I build my application faster with EP?

6. CEP Business Value Value of response CEP value Time Supply Chain Mng. Algo. Trade Relevant dimensions: Time Qulity Flexibility and added value cep alt

7. CEP Costs Cost Complexity Traditional approach CEP Approach Costs: Purchase costs Training costs (Re-) Development costs Maintenance cost Operations

8. CEP Costs Purchase costs Training costs (Re-) Development costs – Business logic – Acquisition Maintenance cost Operations CEP vs. Traditional = > < < =

9. Complexity of Applications Need metrics – Rate of change – Number of event types – State and context management – Rule interdependencies – (Nature of response)... May be common – Opportunity for new value e.g., reflection, introspection, retraction etc.
