Independent of your specific product job, you should take an interest in software technology and be aware of major trends like artificial intelligence (AI) and Internet of Things (IoT). I would argue that every product owner should have at least a basic understanding of core concepts, such as, object orientation, design patterns and architecture principles, as well as agile development practices, such as, test-first, refactoring, and continuous integration. This knowledge helps you make the right product decisions, for example, investigate how AI and machine learning can improve your product or allocate time for architecture refactoring work. It also helps you empathise with the development team and understand some of the challenges the team members experience whilst designing, programming, and testing the product. Learning to program can help you acquire the relevant knowledge—I am certainly grateful that I had the opportunity to learn to write code and architect software systems. But do make sure that you focus on your actual job—to ensure that your product creates as much value as possible for the users and your company. It’s more important that you understand the value your product creates for its users, who the product serves, what makes it stand out, and what business benefits it should deliver than being able to know if a layered or service-based architecture is more appropriate, for example. Additionally, don't interfere with the development team’s autonomy by making technical decisions, which can be tempting for product owners with strong technical skills in my experience. It’s the team’s job to decide how the product is built, not yours. If you feel that people lack the necessary skills to make the right technical decisions, then discuss this observation with the team in the next sprint retrospective and agree on the right improvement measures, rather than you taking over and telling people what to do. Finally, recognise that playing the product owner role and working in product management is as exciting as it is demanding. Don’t feel bad if you lack technical understanding. See it as an opportunity to learn and grow, and expand your product management practice.
