Gartner Application Integration and Web Services Summit
1. Monitors and correlates events outside and inside the enterprise.
2. No communication IMPLIES reality matches model.
Mani Chandy, Caltech
Take Away 2: You’re ready for EDA now
3. Your company is already event driven.
4. You already have the components of the architecture in your enterprise stack, and it’s complementary to SOA.
Key Question for you:
Do the incremental benefits of IT for EDA exceed its incremental costs?
Mani Chandy, Caltech
Organisms Sense and Respond: EDA
1) Streams of data: sight, sound, touch, smell, taste
2) Central nervous system detects the rare event that is a threat or an opportunity
3) Organism responds appropriately to threat or opportunity
4) Too many false positives, a false negative, or too many delayed or inappropriate responses results in death
Mani Chandy, Caltech
Group Sense and Respond: EDA
Three enterprises: lions, hyenas, zebras Critical conditions: fuse information from inside and outside the enterprise
Mani Chandy, Caltech
External Awareness: Questions for you
Does your enterprise monitor its competitors? Government agencies?
Do people in your enterprise correlate information from multiple sources? e.g., correlate flood at a supplier’s factory with deadlines for critical customers.
Mani Chandy, Caltech
Responding to Unexpected Situations
Question for you: A fire has just occurred in a factory that is
going to effect customers severely. Which of two scenarios represents your
enterprise?
1. The CEO doesn’t expect VP Mfg to say anything unless the CEO asks.
2. The CEO expects VP Mfg to tell the CEO.
Mani Chandy, Caltech
No Communication => Reality = Model
1. CEO has an expectation – a model – of the CFO: No communication implies reality matches the model.
2. Space shuttle director has a model for the engineer responsible for shuttle foam insulation. No communication implies reality matches the model.
