It can be a challenge bringing consistency to multiple products which are available from the same company. It’s important to present a uniform look and feel to the end user so they can see the relationship within the product suite.
I’m currently working on a group of products that have been developed with by seperate dev teams. They have evolved to have a range of inconsistencies and with the lack of a style guide in place there is no single source of truth for design.
Working with the product owners is key and our technical authors have experienced and helpful attention to detail. Seeing the bigger picture is a must to spot how UI elements and tasks are handled in the different product systems.
This project also builds towards a future design system where each UI component’s use case is detailed for the whole company to refer to. Other benefits are that UI components are understood by all in the production and test teams and new starters can quickly get up to speed with the available UI components.
