Impact Mapping - delivering what really matters
https://www.toptalks.com/programs/wearedevelopers-2017?chapterId=4999
Product backlogs are much too often flooded with user stories, thwarting the basic agile tenet “Build – Measure – Learn”. Diligent adherence to agile rituals and short iterative cycles will not help if this driving factor is missing. This often leads to efficient teams building the wrong product, or, even worse, just investing into iterative delivery without reaping any of its benefits.
Impact mapping and story mapping are methods that can spark this drive: they support an iterative approach to product design that is often neglected when user story lists are simply prioritised in the product backlog. These methods are highly visual and support the entire project team throughout the process of discovering, prioritising and detailing customers’ requirements together.
In addition to introducing the concepts of impact maps and story maps, this session presents the effects and benefits of using story maps based on real projects along with practical advice for daily work with story maps.

How I learned to stop worrying and to love flexible scope

How I Learned to Stop Worrying and Love Flexible Scope
Join Christian Hassa and Gojko Adzic to discuss how to convince people to embrace flexible scope, not only for startup environments but for big enterprise projects as well.
Not fixing scope too far in the future is one of the cornerstones of agile delivery, but it is at the same time the thing that enterprise stakeholders fear the most. Ironically, being able to change decisions after delivery starts is one of the biggest benefits that companies can get from agile delivery, so it's necessary to stop worrying and embrace flexible scope to get the full benefits of an iterative process.

Keynote: Live it - or leave it: returning your investment into Agile
If you’re involved with software development, there is probably no way you can ignore it anymore: the agile approach. With everyone talking about it, there is a certain pressure to adopt agile methods. This brings with it the danger of introducing a bunch of practices without placing enough emphasis on the two main success factors: continuously improving software and continuously improving teams.
The latter is usually driven more or less automatically by the self-interest of the directly affected individuals – after all, nobody deliberately wants to be inefficient. "Continuously improving software" on the other hand will almost certainly go wrong at first, because trust and feedback are much harder to establish between stakeholders (customers, team) than within a team. This often leads to efficient teams building the wrong product, or, even worse, just investing into iterative delivery without enjoying any of its benefits.
Efficiency is therefore just one component for ensuring a good return on investment when adopting Agile. In this talk, I want to focus on the other part – effectiveness – and how it impacts on the way teams collaborate with their customers. I'll introduce a few techniques (Story Mapping, Specification-By-Example) that support this change and present examples from past projects in the financial and public sector where they proved successful.

Specification-By-Example with Gherkin: from stakeholder examples to living documentation
Scrum Gathering Barcelona 2012
Specification-By-Example with Gherkin: from stakeholder examples to living documentation
Many teams struggle with structuring the discussion of acceptance criteria for user stories and documenting the agreed results. This leads to unfulfilled implicit expectations of stakeholders, ad-hoc assumptions of the team during implementation and frictions between development and testing in a cross-functional team. Efforts for regression testing and the lack of a reliable source of truth about the currently expected system behavior are additional pains emerging from a weak practice for defining and validating acceptance criteria.
In this session I want to show how specification-by-example and acceptance test driven development can help to address previously described challenges and problems. The presentation will cover theory as well as examples and practical experience from own projects with brief demos how these concepts can be put into practice using SpecFlow, an open source tool for automating Gherkin specifications in .NET.
Attendees should get an initial understanding of the concept and its benefits as well as concrete pointers how to get started with applying the concept in their own projects.
The session targets an audience that is familiar with the basic Scrum concepts and has been working in Scrum projects already. Ideally, attendees of the session feel one or more of the challenges and pains described at the beginning of this abstract (and the session summary), which are addressed by this session.
