Declare Dependency Independence!

Any sufficiently interesting software system will rely, in part, on code we don't control. In a world teeming combinatorically with APIs, how do we fulfill our responsibility for business outcomes? With techniques to cope more effectively with dependencies: to reduce their surface area and associated risks, to track small updates more often, to find breakage earlier, and to preserve simple, sensible options we can exercise when something -- inevitably -- breaks.

As a mob, in a small codebase with poorly controlled dependency risk, we'll quickly put the business in a bad spot. Then we'll test and refactor to control the risk, and compare. Don't know what to try next? Take the keyboard. Got an idea? Step away and talk someone else through it. You'll leave with a powerful strategy to keep your software valuable and working. We'll also send you home with a free bonus development practice to accelerate your team's learning. For a limited time only!
