Partition to Reduce Complexity



Training


Mike's Notes

  • A linear increase in functionality and dependency leads to a logarithmic increase in complexity
  • The rise in complexity and risk of failure in big IT projects is a power law.
  • Partition and simplify to reduce complexity
  • Partitioned chunks of functionality then suitable for Agile teams
  • The maths is sound
  • Puts maths behind what Martin Fowler writes
  • Not in contradiction with Zachman ontology
  • Complements Google reWork study results
  • Training is expensive
