 Hello, everyone, and welcome to this talk titled Connecting End Users and Developers with Requirements Bazaar. My name is Ishtwan Koren, and I'm from the RWTH Aachen University in Germany, one large technical science engineering university in Germany, Europe. And as a research institute in computer science, we're working a lot with end users. So we have projects where we build apps for construction workers on the construction site, or we have another project where we build HoloLens applications for helicopter manufacturers and astronaut training. Pretty cool stuff. And what we discover in all these projects and what we notice is that a lot of ideas, of course, are coming from the end users. And if you look at how you usually collect end user feedback, it's like this in the open source world. So this is Baxila from Mozilla. For the end user, it's very confusing. A lot of fields to fill out. Or there is the Android bug tracker. There's a lot of fields to fill out. What we tried is JIRA. People didn't understand things like fact-ticked version and fixed version and so on. But what we found out is that people love sending, filling out a short text box and sending us feedback via email, for example, or via the Android App Store. That's another very common thing for end users, to just fill out there and wait for help. But that doesn't really scale. So it's very hard for developers to accommodate for the wishes of a lot of end users. And we also want to integrate the end user feedback into our continuous life cycle. So there's continuous integration, delivery, deployment already in place in a lot of projects. What is missing is here the continuous innovation factor. And to this end, we came up with a software called Requirements Bazaar. And its structure is very simple. So you have projects, you have categories within projects, and you have requirements. And people just need to click a box, a plus button on the bottom right, and a small text field opens up. People can enter there. Then developers can come and comment or other users can discuss and vote on the features. So the key ideas here is to build a very simple platform where end users, developers, designers, and researchers can come together and discuss and prioritize new ideas. Also, the end users, they want to be aware of what is currently going on, what developers are working on. So it's possible in the Requirements Bazaar, integrate in any context. So we have REST APIs. You can integrate in your app to just push ideas, like this feedback box that you know from many apps. And export options for developers if they want to use the ideas in their actual issue trackers, like GitHub issues, or JIRA. The details of the Open Source Requirements Bazaar is so we have a progressive web app. It's responsive. Mobile first, you open it. And after the first launch, it loads really fast. It insults on your home screen something we heard this morning. It really boosted the usage. We have Polymer Web Components, a REST backend based on Java. It's on GitHub. And we use JIRA and Jenkins for the continuous life cycle. Outlook, what we are currently working on, is fix the integration with JIRA and GitHub. So to offer a button, an EXO requirement to export the issue to JIRA, we have one guy working on the game verification aspect. So you get points and badges if you develop something or if you post new ideas. So that keeps the users engaged and developers as well. And add design tools so that designers can upload different versions of a new button, for example, and users can vote. Embracing new communities outside of the pure software development. So for example, we found that a community in Afghanistan Kabul is actually using the requirements Bazaar to plan the digitalization of their country. It's really interesting to see and localization. So we have people translating it to different languages. So that is where we're also looking for contributions. So contacts are here, requirementsbazaar.org. Feel free to try it out. And this is our email address. And that is my Twitter handle. Thank you.
