Last time, we have discussed, how to prepare a design review like an expert. There are three items that should be prepared:

• C4 model
• User stories and use cases
• Design decisions

In this article, I will use a practical example to show you what is a design review looks like. Some discussions with too many details will be skipped, and only demonstrate the critical designs.

User Stories

First, we are going to define the user story. Like the previous article mentioned, user story aligns with the context perspective in C4 model. Therefore, we write down the user stories clearly.

This time we are going to do the function of giving gifts. And, the whole story is as follows.

• A User can decide how many of the same gifts they want to give to others at a time.
• As long as the user has enough money, then there is no limit to the number of people giving gifts.
• After finishing giving gifts, it must inform both sender and receivers that everything has been done.

Use cases
