A brief document which will cover all of the process and scope that will be involved in designing this project. Ranging from research, design to testing and validation.

User research to fully understand who we're designing the product for(Needs, Goals, Motivations) and also how the findings are linked to design solutions. Deliverables won't be the same as methods used for research can and will change depending on the project. Examples of deliverables include Proto-personas or User personas, Scenarios, affinity notes, Taskflows, Journey maps etc.

First prototype will include either just sketches, or digital prototypes just for testing for iterations depending on the project. Second prototype(High-Fidelity)will include a pretty prototype with colors, typography etc. that will resemble the final product. Again this is for testing with real users to validate and test for iterations.

A design system will include styling guides like color, typography, shadows, borders etc. and how to use them. Alongside reusable components like cards, buttons, sections etc. And any other tokens that will be reused. The design system will significantly improve designing and development speed, even for future changes with another designer.

The final design is the end-result or product. This can be a website, web app, Table/Mobile App or any screen interface. All of which optimized for handoff to development. P.S I don't do development, but I can help you with no-code softwares.
