Every single product or service can benefit of employing a user experience (UX) designer. Unfortunately there are always way less good designers than projects and therefore they have to be selective.
Both the designer and the project benefit if the designer feels happy. In a selection process every designer has his or her own ethical principles to start with. When a project passes the moral test, please, consider:
- What he/she can bring to the project?
Knowledge? Skills? Positive attitude?
- What he/she expects to get back?
Moral satisfaction of making a good product?
Or making a world a better place?
Or creating a perfect icon? Or expressing the inner self?
- What expertise is already presented in the project team?
Who is in charge of the product/company development strategy?
Who defines product/service functionality and visual style?
Who decides what (brand) message the product communicate?
- What can the designer add?
On what level the designer have to be involved? Strategic?
Or the help is needed in a tactical realization of the defined goal?
Or the product needs someone who will prettify the existing solution without asking questions?
As you can see there is a world of possibilities on a different levels. Some designers aim for perfection on one of them, some on another. If both the designer and the employer are on the same page about the role and the level of involvement of the designer in the project and satisfied with answers to the questions above, you should proceed.
Here you will find some information of what can you ask and expect from the designer and how to communicate a UX projects needs and results effectively. Good luck!
