+2. NN Package WG
+ - Tasks
+ + Common IR design : Hyeongseok Oh(@hseok82-oh), Cheongyo Bahk(@ch-bahk),
+ Seok NamKoong(@sk-namkoong)
+ + Importer/Exporter
+ + Custom Operator Support
+ - Members

+There is one unique workgroup containing most _nncc_ tasks. They are working closely together as a
+front-end to the runtime. Since _nncc_ and _nnfw_ will be merged soon, it is natural to think of
+them as one team. In fact, most of the members are already involved in two things.
+
+4. Compiler Frontend
+ - Tasks
+ + NN Compiler (@in memory) IR design & implementation : Jonghyun Park(@jh1302.park)
+ + TensorFlow model support
+ + ONNX model support
+ + Target independent graph optimization
+ - Members
+ + Seok NamKoong(@sk-namkoong), Cheongyo Bahk(@ch-bahk), Hyun Sik Yoon(@hyunsik-yoon),
+ Jiyoung Yun(@jy910-yun), Seongwoo Chae(@sw4670-chae), Jiseob Jang(@jiseob-jang),
