The author reflects on their experience in Barcelona, where they struggled to adapt to the local meal schedule. Breakfast is light, lunch starts around 2 PM, and dinner doesn't begin until 9 PM, with restaurants bustling until late. Despite being physically able to adjust, the author feels emotionally resistant. This resistance stems from a deep-seated belief in the value of daylight, shaped by personal history and cultural influences from the U.S. The contrast between the Spanish emphasis on communal meals and relationships and the author's value placed on daylight illustrates how differing beliefs lead to conflicting daily rhythms. The article connects this personal experience to challenges in product management. The author recounts a situation where a lead engineer encouraged a shift to a more collaborative approach in writing product tickets. Although the author could technically adopt this new method, they resisted it emotionally, rooted in their belief that clarity and control were essential for success. The engineer's request required a shift in values, something that can't be accomplished through logic alone. The author emphasizes that cultural values and beliefs need to be understood and addressed for real change to happen in work environments. To effectively shift values within a team, the author outlines a three-step approach. First, uncover the protected values behind resistance by asking what individuals fear losing with a new process. Next, assess whether team members have experienced the benefits of the proposed changes; without this experience, their resistance is likely to persist. Finally, create the conditions for those experiences to occur, ensuring that team members can see the value of the new approach in action. Each step builds on the last, highlighting the importance of addressing beliefs before expecting any change in behavior.
