Pharo proved to be instrumental in delivering a working system, especially when it comes to understanding what’s going on under the hood during development. It also enabled to discuss and explore issues with non-technical people easily in the live, interactive environment over screen share sessions, as well as to quickly understand (and fix!) what was going on on production sites using the integrated VNC server said Philippe Back, lead developer.
