Knowing what our design colleagues are working on can be tricky as we are many designers working for different areas and timezones. To help with this, we have a slack channel #des-wip that we can use to share our work.
The goal of this channel is to communicate in a brief way what projects we are working on and improve visibility and future collaboration. The purpose here is not feedback oriented. If there is a case where you want to give/get feedback, there are other design specific channels for that, like #des-dxp, #des-internal, #d-product-design, #d-comm-design, #t-lexicon or just DM the person directly.
You just need to choose one work you want to share with your colleagues and post it in the channel by following the message-structure you will find there.
Every designer should post every 2 weeks.
