Trust your design partner
If your design firm uses the words, “trust us” in a presentation, then you should NOT trust them. That’s lazy and does nothing to instill confidence or illustrate their expertise. If they’re proposing an idea, they need to back it up with research and a solid rationale.
If they back up their design decisions with solid rational and map everything back to the project and messaging goals, then you should trust them and be willing listen to all the ideas they bring to the table.
Be open to being uncomfortable. You want your design firm to push you, not unnecessarily or beyond the context of the project brief and goals, but they should be championing work that will help you improve your business and sell more beer.
Both you and your design firm should have the same goals (which is to grow your business). But you are more likely to have emotional ties to your brewery in addition to your financial investment. Feeling nervous during this process is normal. You are, after all, spending loads of money and time on something that is extremely important. Lean into your design firm and work with them to create great work together.
