Because redesigns can be so expensive, complex, and time-consuming, building a case and getting a budget is often challenging. They also involve much more than just design work; there’s SEO, navigation, and content creation.
Adding to the difficulty, design seems so subjective and personal, that sometimes a high level stakeholder liking or not liking the website is reason enough to start or nix a project. What’s worse, after the new website is live and the bill has been paid, it’s not always clear whether the project was a success by any metric other than “we like the new one better.”
