What is different?

Before

Sprints

Little teamwork, multiple projects in sprint

Planning & sp estimation

Dispair over improvement

After 1 year

Release when ready (needed)

Teamwork, despite multiple projects

T-shirt sizing

Team focused, management supported improvements

Key tech debts solved

2010-09-24

Mattias Skarin 24

Nailing down the problem behind the improvement is getting harder - requires more effort and thinking..

25

What is same?

Still multiple projects (but better risk mix)

External clients behaviour not changed

Mattias Skarin 25

.. but management are working on itand no longer considers this a team problem
