KONE is one of the global leaders in the elevator and escalator industry. KONE developed Microsoft Access application for their internal use to support 3P method (Production Preparation Process). The application is customized for their factory in Ústí nad Labem (list of employees, production lines, etc.). We were asked to create a couple of new features in the current application (e.g., automatic email reporting, new Abnormality type – KAIZEN, etc.). The current functionality had to be preserved, and we were asked to improve the performance.
