  2. 2. DTAC Enterprise Architecture Story 6 blind men attempting to conceptualize “what is an elephant” The whole truth is difficult, if not impossible, to achieve …20 April 2011 2
  3. 3. Business AnalogyScenario 1. Elephant is an animal on heaven that god would like the blinds to build on earth; it runs around a lot and grows very quickly 2. The closer the elephant on earth matches the one on the heaven, the bigger the reward 3. Each day the blinds have only 1 hour access to the elephant on heaven when it sleeps in different postures 4. Understanding there is no perfection on earth, God does not speak to the blind but pays out the reward based on his slowly changing criteria everyday 5. There is a God servant who is good at guessing god’s rewarding criteria20 April 2011 3
  4. 4. Business AnalogyInitially … The elephant was young and small, there was only 1 group of blinds working to receive God’s reward: 1. The blinds were able to use the 1 hour window to feel out the elephant on heaven quite thoroughly 2. God’s evaluation criteria was simple and straight forward and the God servant was able to communicate God’s wishes effectively 3. They constructed earth’s version of the elephant very close to the truth and received good rewards20 April 2011 4
  5. 5. Business AnalogyNow … The elephant is big and there are many groups of blinds competing for God’s reward : 1. The blinds are having a lot of difficulties using the 1 hour window to feel out the elephant on heaven due to its shear size 2. God’s evaluation criteria was getting more and more complex due to the competition making it harder and harder for the God servant to communicate God’s wishes effectively 3. The blinds start loosing touch of what their elephant on earth look like 4. Coordinating work between the 6 blind builders is difficult as each need more time to work on they own portion20 April 2011 5
  6. 6. Business AnalogyA new game plan … Build a common model elephant for all 6 blind builders: 1. Hire a new blind architect • Good at sculpting clay models • Good communication skill to interpret God servant’s complex language 2. Tasks for the new blind architect • Listen to the original 6 blinds describing how their elephant on earth now looks like and build a clay model for all to use • Consolidate all information gathered during the 1 hour access to the elephant on heaven and use it to update the clay model • Interpret God servant’s complex requirements and use it to prioritize work items for the next day by showing it on the clay model20 April 2011 6
