Planning for Design Stage
Planning is the stage of choosing the technology stack and software development methodology, defining the deliverables, and estimating the timeline and resources to complete the project.
Other sensitive decisions include creating the content structure and sitemap, wireframing, planning the layout, including UI and UX design.
You should consider that deciding on a sitemap during the planning stage is fundamental for the whole project. It involves organizing the structure of the website, how many pages and functions will be connected based on their importance, and what content and functionality must be rolled out with the first release.
