In 2018, Apple's highly anticipated iPhone battery management feature update led to a 20% drop in user engagement within a year. This unexpected outcome can be attributed to the company's failure to prioritize user needs in their product roadmap. A common mistake professionals make is not gathering user feedback and incorporating it into the development process. Many companies assume they know their users' needs, but this arrogance can lead to products that are out of touch with reality. For instance, Google's "Google Plus" social network was a failure due to its attempt to create a universal identity system, which users saw as invasive. The implication is that professionals must put user needs at the forefront of their roadmaps. WHY Losing 20% of users can be catastrophic for a company's revenue and reputation. This mistake can be avoided by prioritizing user feedback and needs. USE Prioritize user feedback in your next roadmap update by adding user testing and feedback sessions. Review your current user journey mapping to identify areas where users are dropping off. Consider using the Jobs-To-Be-Done (JTBD) framework to understand your users' underlying needs. Conduct a survey to gather user opinions on your current and proposed product features.
