When a client comes to me with a website issue, a question I've learned to ask well before approaching the development team is "What browser are you using, what version do you have and what settings are configured". We need that information to try and recreate the issue before we can even begin to troubleshoot it.
We've recently started implementing 3 month follow-up meetings post a site/app/project launch with our clients as a formal part of our process (meaning it actually goes on the task list then turns into a meeting). I'm writing this post at a coffee shop, just a few minutes after completing one such review and reflecting on why we didn't implement this formally much sooner.
Last month I flew to DC to present at HOW Interactive on the topic of Enagaging Multiple Stakeholders in an Interactive Design Project. I had a great time presenting in Washington and in particular enjoyed the feedback and questions from the attendees. The topic is one that is near and dear to our hearts here at Raised Eyebrow, working as we do most of the time with non-profit organizations, which means also working with multiple stakeholders.
