Using Feature Flags in Development
WorkshopFree
Ensuring your code is ready for production without enabling your features to your entire user base used to involve a lot of guesswork. By using feature flags, we can allow our development teams to preview work-in-progress features and unreleased functionality in production without redeploying our code.
In this workshop, we’ll run through the fundamentals of feature flagging on both the client and server sides. We’ll cover working with LaunchDarkly’s SDKs within the context of a React application with a node backend, flagging at different places in the stack and give an introduction to rule targeting in the platform.

Keep Calm and Deploy On: Creating Safer Releases with Feature Flags
Creating and deploying new software is risky. We've all seen how easily bugs arise, causing software to be poorly delivered or to the wrong people. What's more, depending on how tightly we couple our systems and services, they can interact unexpectedly and unfortunately with existing software or hardware. Beyond unintended consequences, we can also find that people can use our services for nefarious purposes. It's essential to have safety nets in place when things don't go as planned or people attempt to break the rules. In this session, we'll discuss how feature flags can work in both temporary and permanent scenarios to enable you to break the quality triangle and deliver quality promptly.

Orders & Magnitude
Orders of magnitude matter. Things don't go up order of one every time. Organising people in a group requires disseminating information and its interpretation and, most importantly, its distribution. Remote working and asynchronous collaboration have become the norm, meaning that distributed teams have taken their silos of knowledge with them. The impact of this has compounded any organisations experiencing a skills gap with a skills distribution problem, increasing the importance of good documentation and transparent interaction processes. In this session, we'll go over the fundamentals of requirements engineering, looking at how orders of magnitude scale alongside the expansion of scope and additional requirements. Lastly, we'll discuss how you can apply elements of platform thinking to your everyday projects.
