It's helpful to develop client trust from the start, challenging a hazy brief and seeking access and dialogue throughout the design process to avoid a blanket dismissal.
Throughout the project, a competent designer must sell ideas, concepts, and variants on a theme, minimizing the risk of outright rejection.
Don't be concerned if you get a rejection. This is when a designer's persistence and communication abilities are put to the test.
Engaging in a discussion is critical since this is when the client is most engaged and you can identify the key motivations that will make them adore the next route you show them.
It's critical to demonstrate the evidence and logic behind a smart design. Try to anticipate all of the questions a client might have before giving a presentation.
Provide real world examples.
Recognize the client's dislikes.
Remind yourself that you're a commercial designer. You've been hired to assist a client with a project. Always strive to create good design, but understand when to fight and when to simply give the client what they want.
