Digitale Leute – Build Better Products


Why you need to update your product development with The Product Manifesto

Conference Stage 2

When David published his first article, where he called out the need for a product manifesto, he did not anticipate how much it would resonate with the product community. In this article, he expressed his feeling after working in 10+ companies that most companies are good at developing features but miss out on the value. His article made quite an impact: Over 100.000 people read the article, and soon The Product Manifesto was published. Product managers started printing the principles and changed how product development works in their companies. In this session, David and Thomas will discuss why a product manifesto is needed, go through some principles, and open up the discussion to the audience.
