We use mindmaps for visual aids when it comes to planning a website, the content and the sitemap. It allows us the flexibility needed to present and discuss the existing sitemap, the proposed sitemap and menu(s) for the new website.
Menus & Breadcrumbs
We've included menus in the Planning stage. However, that comes with a caveat, due to the enormity of a clear and structured menu and sitemap, it will be discussed pretty much throughout the planning, design and implementation stages to ensure it's perfect. It is that important.
