The value of a product is the number of problems it can solve divided by the amount of complexity the user needs to keep in their head to use it.

Working Backwards: A New Version Of Amazon’s “Press Release” Approach To Plan Customer-Centric Projects (via) I’ve long wanted to give the Amazon “future press release” trick a go—start a project by writing the imaginary press release that would announce that project to the world, in order to focus on understanding what the project is for and how it will deliver value. Jeff Gothelf has put a lot of thought into this and constructed a thorough looking template for writing one of these that covers a number of different important project aspects. # 2nd June 2020, 3:54 pm


Lessons from 6 software rewrite stories (via) Herb Caudill takes on the classic idea that rewriting from scratch is “the single worst strategic mistake that any software company can make” and investigates it through the lens of six well-chosen examples: Netscape 6, Basecamp Classic/2/3, Visual Studio/VS Code, Gmail/Inbox, FogBugz/Wasabi/Trello, and finally FreshBooks/BillSpring.
