JD is a system developed for John Deere Serbia and consists of 3 main parts. The 1st part is an Android application – the main purpose is to help farmers report any kind of malfunction of their tractors, harvesters etc. Through the app (with only 2 clicks), farmers are able to contact their John Deere service whose operators have all the information about their product – that way the communication became faster and easier. The 2nd part is related to the Service application which helps John Deere’s management to monitor all malfunctions of their machines and to get feedback regarding the same. Service app keeps track of the problems reported, analyze the data and report to the production management. The design was developed by Zesium, both graphical (colors, icons, etc) and functional (UX, screens, buttons, etc). It was adjusted to be easy to use but at the same time, inventive and modern. JD application was a complex development process which involved both farmers and the internal part of John Deere – the importance of good feedback from both sides regarding the application was essential for Zesium.
