When starting a new web project, it’s essential to have an understanding of the features and abilities on each individual page. Sometimes, before putting together wireframes, the visual designer may have questions about what the level of importance of actions and features on a page are. This can also make certain that the client or project manager knows how the site will essentially lay out.
Enter the Page Description Diagram, or PDD for short.
Why Use A PDD?
A PDD allows you to sit down with your client/project manager and list out the features of each page in a non visual way (no outlines, just feature listings). This means that you can emphasize what is important on each page and if, due to timeline constraints, you find yourself leaving out certain functionality, you can make sure you’re not cutting the wrong things out.
How Do I Use A PDD?
The main structure of a PDD is 4 columns. The first three columns represent the features and objects that need to be on the page, according to the tier of importance above them. This means that column one should hold items like branding, login, welcome content, etc. Each item should include a little description about what they are and what they need to do. The last column is for notes. Pretty straight-forward. Now everyone is aware of what each page does and what will be on it, as well as what will be emphasized most.
Should I Always Do This?
A PDD is a guideline and breaks interactions and features out into detail. It may not be necessary on every project, but it can definitely help some visual designers, project managers, and clients if a project has a lot of moving parts. This will give expectations of where things will be when wireframes and mockups are presented later.
Sounds Great, But How Do I Make One?
Luckily, I’ve taken examples and created a template of my own, which I now pass on to you. Seriously though, there are several PDDs across the internet and I’ve created a format that has suited me the best. You may download them here:
Do you use PDDs? Do you use something else that’s similar? Feel free to let me know. I hope these can help you when needing to get started on projects!

It’s more than a logo or word, it’s your companies vision. This is how you want people to perceive your company. Your brand. By changing your public image around or not keeping it consistent, you’re telling your consumers that you’re not sure what it is that you do. Or what you want to be.
