A detailed, vertically-oriented mind map infographic on a dark background, titled "Product Design Methods in a Mind Map," illustrating the five stages of the product design process: Understand, Define, Ideate, Execute, and Validate. Each section contains branches with icons and text describing specific methods like market research, prototyping, and usability testing, with a footer referencing adapted content and a URL for more insights.

I discovered Mei Zhang’s post about when it’s the right time to apply specific product design methods.
And, for sure, it’s a common question not just among UX/UI designers, or even professionals related to design.
Just keep in mind. As a designer, designing pretty and useful interfaces and knowing user experience concepts and research methods are not enough to design a product.
