Hypothesis-Driven Development

Nothing will help a team deliver better outcomes like making sure they’re building something the user values. This might sound simple or obvious, but I think after this week it’s likely you’ll find opportunities to help improve your team’s focus by testing ideas more definitively before you invest in developing software. In this module, you’ll learn how to make concept testing an integral part of your product pipeline. We’ll continue to apply methods from Lean Startup, looking at how they pair with agile. We’ll look at how high-functioning teams design and run situation-appropriate experiments to test ideas, and how that works before the fact (when you’re testing an idea) and after the fact (when you’re testing the value of software you’ve released).

The best products are tested for usability early and often, avoiding the destructive stress and uncertainty of a "big unveil." In this module, you’ll learn how to diagnose, design and execute phase-appropriate user testing. The tools you’ll learn to use here (a test plan template, prototyping tool, and test session infrastructure) are accessible/teachable to anyone on your team. And that’s a very good thing -- often products are released with poor usability because there "wasn’t enough time" to test it. With these techniques, you’ll be able to test early and often, reinforcing your culture of experimentation.

You’ve learned how to test ideas and usability to reduce the amount of software your team needs to build and to focus its execution. Now you’re going to learn how high-functioning teams approach testing of the software itself. The practice of continuous delivery and the closely related Devops movement are changing the way we build and release software. It wasn’t that long ago where 2-3 releases a year was considered standard. Now, Amazon, for example, releases code every 11.6 seconds. This week, we’ll look at the delivery pipeline and step through what successful practitioners do at each stage and how you can diagnose and apply the practices that will improve your implementation of agile.
