Abbott Labs is a global, broad-based health care company devoted to discovering new medicines, new technologies and new ways to manage health. One of its products, a device used by laboratories to analyze blood, was developed using a proprietary GUI toolkit that although originally suitable, was viewed now as a significant constraint to the ongoing evolution of the device. Consequently, Abbott decided to replace this toolkit with the Qt C++ framework. To speed this process, Abbott engaged with ICS to develop the replacement application. Additionally, ICS helped guide Abbott engineers in implementing best approaches to integrating Qt into their application.
