First and foremost, it's crucial to remember that you're the expert in your field. You've been hired to provide your professional opinion and expertise, so don't be afraid to speak up and defend your work. If you're confident in your design choices, explain why you made them and how they benefit the user experience.
Don't let anyone undermine your expertise or authority. It's also important to listen to their feedback and understand their concerns. Sometimes, they might have valid points or ideas that could improve the design. However, if you feel that their feedback is unreasonable or not in the best interest of the user, respectfully explain why you disagree and provide alternatives.
Another strategy is to involve stakeholders and users in the design process. This can help you gain their buy-in and support, and they can provide valuable feedback that can help make your design even better. By involving them in the process, you're also showing that you value their input and are willing to work collaboratively towards a better user experience.
The hot-tub in the Cathedral
One effective technique for dealing with fault-finding clients or managers is to provide them with something to nitpick on purpose. This might sound counterintuitive, but it can be a powerful way to get past their ego and move forward with the design.
For example, you could intentionally include a minor typo or design element that you know they'll notice and comment on. This can help satisfy their need to find flaws and give you the opportunity to redirect their attention to more important aspects of the design.
Another approach is to provide multiple design options that are deliberately different in small ways. This gives the client or manager the opportunity to express their preferences and feel involved in the decision-making process. By providing them with choices, you're also demonstrating your expertise and ability to create a range of effective design solutions.
Ultimately, if all else fails, be willing to walk away from the project. It's not worth sacrificing your professional integrity and expertise just to appease a difficult client or manager. Be honest about your concerns and your willingness to work collaboratively, but also be willing to step away if the situation becomes too toxic or unproductive.
Dealing with fault-finding clients or managers can be a challenging aspect of the UX design process. However, by being confident in your expertise, listening to feedback, involving stakeholders and users, and using techniques like intentionally providing something to nitpick, you can navigate these situations and create effective, user-centric designs.
