• During early 2010’s, TUI UK&I ran project Phoenix, replacing legacy
mainframe systems with an Oracle database driven booking system,
SAP Hybris, SAP Finance etc. This project did deliver the required
change, but not without considerable pain.
• Following this experience, IT in TUI UK&I was very process driven:
• Big projects with big budgets
• Focus on delivery on time and budget
• Functional teams with tight scope, defined roles and multiple hand-
offs
• Time was spent on close resource management and project plans.
• Development was largely supplier based, slow and expensive.
• Architecture was heavily proscribed, with detailed up-front solution
architecture documents defining every aspect.
TUI UK&I IT – 2016 – process over value

• Cynefin model – one of my favourites
• To survive we must be more flexible, move faster,
eliminate waste
The world is ruthless!
• EAs need to help seek opportunities to
• remove duplication
• increase convergence of common tools & processes
• identify opportunities for economies of scale
• We need to be able to compare apples with apples
Change is accelerating, decisions are made between complex and chaotic
