UXD [ˌjuːeksːˈdi]: stands for User Experience Design.

UXD or UX aims to give the users a positive experience in accomplishing their tasks at all stages: before, during and after the task. The bottom line is to boost confidence and limit frustration and confusion. Just because it’s pretty doesn’t mean it works.

The official definition (Oxford Dictionary) is „the oval experience of a person using a product such as a website or computer application, especially in terms of easy or pleasing it is use.”

User experience design is responsible for being hands on with the process of research, testing, development, content, and prototyping to test for quality results.

Version control

Version control [ˈvɝː.ʒən kənˈtroʊl]: systems that manage changes to code over time.

A version control helps developers to keep track of the old versions of a project and – if a mistake was made in the new version – jump back to them. It also enables them to work on the same project at the same time: It stores the two parallelly made modifications in seperated branches that later can be merged.
