I’m reading a book called Getting Started in Consulting right now and Alan Weiss brings up a simple way to improve your standing with clients. When people call or email you, get back to them within 3 hours. Don’t just make this a guideline, make it a foundational rule and promote it as such.
Think about how nice it feels when you leave someone a message (or email) and they get back to you with an answer very quickly. You feel like this person/firm is well-informed and capable of producing results. Surely, there will come times when an answer can’t be given right away but you can still keep your promise by acknowledging the request, restating what you believe they need, and stating what you will be doing to meet that need.
