  • 3. THE PROBLEM OF COMPLEXITY Commercial in confidence | Copyright © 2007 Fronde Systems Group Limited and ObjectWatch, Inc
  • 4. Key Assumptions
    • IT failures are not the problem, they are symptoms of a problem
    • The real problem is enterprise complexity
    • Control complexity and IT success follows
    • Fail to control complexity and nothing else matters
    • Complexity Control is Job 1!

    • Intentionally
    • Accidentally
    • Not At All

  • 13. Partition to Reduce Complexity
    • Step 1 – Partition, Simplify, Prioritise, Iterate

  • 14. Conclusion - In Simple Terms
    • Partition to slash complexity
    • Simplify the partition as much as possible
    • Iterate through the subsets of the partition
