Distance rules out continuous
collaboration and face to face communication
Distance limits continuous
collaboration and face to face communication
It’s a large, complex problem with a large,
complex solution.
Must standardize some working practices and
team structures

Delivery Scale Challenge
7
Drivers
• Very Large Programme Recovery
• Multiple Large Programmes in parallel
Vision
• Deliver Programmes to plan by adopting large scale Agile Model
• One global project delivery team
• Test driven development
Methods
• Common governance across multiple vendors
• Common Function Point metrics
• Continuous integration • Identical development
platforms • End to end project and
dependency management

Team is distributed, not
integrated
Each team is self-organizing
and empowered
Collaboration is at a distance
Retrospectives are used by Teams and Programme
Backlogs of work at team
“divides”
Definition of “Ready”/”Done” vital to success
In excess of 50 teams delivering simultaneously
