The observations

Stuff gets delivered, but it takes a long time

Delivery can not keep up with the speed of market change

Processes are avoided resulting in shadow delivery methods

Low levels of innovation

Reduced technical capability

D&T’s capability does not match Sainsbury’s market conditions

7

Transformation ideas

Outsource what you can’t add value too.

Bring in-house things which when you do them well, or in which you innovate, can add value.

Use utility computing.

Build skills and competencies.

Use autonomous self contained teams which are able to deliver end to end.

Focus on small incremental changes and fast feedback loops.
