From Business Analysis to Business Analogy – Alignment through targeted metaphor
45 Mins
Talk
Beginner
Those of us who have worked in software for a while will have heard "That's what we asked for, but it's not what we needed".We tend to think about the solution we're building rather than understanding the problem we're solving.An expert will often use an analogy or a metaphor to explain the underlying problem domain. But when we start designing the system, we talk, and think, about the system as an abstract solution. We discard a useful tool for understanding and alignment.At RiverGlide, we have seen code reductions of up to 90% when using a metaphor that fits. A good metaphor is also easy to share without losing any understanding.In this talk, you'll hear about memetics and metaphor from the psychology research viewpoint. You'll hear examples of projects that diverged wildly in their understanding, and some reasons why. And you'll hear examples of how the right metaphor can make a complex problem into a trivial solution. -

It's Metaphor All The Way Down - Sharing Understanding through Common Stories
45 Mins
Talk
Intermediate
Eric Evans introduced the idea of Ubiquitous Language in Domain Driven Design. This means that within a certain (bounded) context, each word or phrase that we use has a specific and well-known meaning. This is only part of the understanding though. What are the threads that tie all those parts together?
This talk explores how metaphors and consistent narratives can foster ubiquitous understanding in a certain context, how metaphors can offer new insights to a problem/solution domain that we thought was stale, and how when the metaphor starts to feel forced that it may be indicating the edge of a bounded context.

Robot Handles - Giving Selenium a Helping Hand
45 Mins
Demonstration
Intermediate
By far the most common way to use Selenium to interact with an application is to code tests that have intimate knowledge of the underlying application. This is simple, but brittle. Others may try to make the test code intelligent, leading to a very complex testing framework. There is a middle ground.
Imagine that we are building a robot to move eggs. A simple robot can deal with identical eggs, but is brittle as soon as new eggs are introduced. An intelligent robot could adapt to variations with sensitive touch sensors. Or, we could use egg-holders with a handle on top. Now all we need is a simple robot that understands handles. If we then want to move something instead of eggs, we just need a new holder – the handles and the robot remain the same.
In this session you’ll learn the metaphor of Robot Handles, discuss ways that we can add meaningful interaction metadata into the application as we build it, and demonstrate how that can be just as helpful for humans as it is for robots
