2021 Retrospective

Based on An End of the Year Retrospective by Pat Kua.

What happened during your year?

Go through your planning tools (e.g. personal and work calendars, to-do lists, journals, etc) and list any events or activities (by month) of significance to you. Capture these as if you were a neutral bystander.

Examples might include: “Moved house”, “Took part in a virtual panel”, or “Read Lord of the Rings for the 2nd time”

Thema der LVA

Jour Fixe in Advanced Software Engineering.

Beschreibung der LVA

Advanced Software Engineering (ASE) hat das Ziel, Konzepte der Erstellung von Softwaresystemen anhand eines realer Projekts zu vertiefen. Dabei wird besonderer Wert auf die Erarbeitung von Entwicklungslösungen im Team gelegt. Fertigkeiten aus der LVA 'Software Engineering und Projektmanagement' (SEPM) werden vorrausgesetzt. Das Projektumfeld wird im Vergleich zu SEPM um fortgeschrittene Technologien und Anwendungsgebiete erweitert. Kurz gesagt entwickeln Studierende somit im Team ein neuartiges, technologisch anspruchsvolles Softwareprodukt.

Die Studierenden werden im Laufe des Semsters bei wöchentlichen Treffen (Jour Fixe) von ihrem Tutor / ihrer Tutorin betreut. Die Studierenden arbeiten prinzipiell in Gruppen von 5-6 Personen. In diesem speziellen Fall besteht die Gruppe allerdings nur aus drei Personen.
