Introductions“I help teams of smart people

learn to work together more efficiently, to deliver better software faster”

Do you aim to build features that delight the customer?

How long does it take a feature to go from an idea to into the hands of the users?

We can’t afford to wait for long dev cycles

Today’s market moves fast

Our delivery strategies need to move just as fast

Agile helps us meet these challenges

But are classic agile practices enough?

The essence of BDD

Collaborate to discover requirements and identify uncertainty

Using examples at multiple levels

And a common language to build a shared understanding

To deliver software that matters
