**This all changed** with the introduction of the Workbench at the end of 2019. The tool digitalised and automated many of these offline processes that were still being performed manually, thereby radically **reducing the transaction costs** inside the firm. As such, the Workbench allowed Haier’s EMCs to **self-organise in a wholly digital manner**.
However, the tool not only radically decreased transaction costs but also brought three other advantages: **Market Efficiency**, **Ecosystem Transparency**, and **Common Prosperity**.
