Understanding who your users are and what motivates them to use your product is an essential component to the development process. Creating visual user personas allows you and your team to better connect with your customers' needs and tailor your product and marketing efforts specifically to them. User persona visuals will facilitate stronger product development and higher conversion and satisfaction rates.
Understanding who your users are is the first step in the product development process. The second step is to understand how these users will interact with your product. Creating customer journey maps is the best way to internalize how your customers will come across your product, engage with it, and ultimately decide whether or not to purchase it. By creating customer journey maps, product designers are able to isolate holes or flaws in assumptions that may have been made, and can tighten up the user experience and interface to meet customers' expectations.
From a technical perspective, a product may work perfectly and solve the exact issue your target user is experiencing. But if the product design isn't visually appealing and simple enough for the user to understand, the product will fail. The best way to experiment with different product design ideas and concepts is to create wireframes or mockups. By creating wireframes and mockups and discussing them with your product development team, you'll be able to agree on the cleanest, most modern, and most user-friendly product design.
