+# 2019 Workgroups
+
+For faster communication and development, we organize workgroups (WGs) based on major topics
+described in [WBS of 2019 NN Acceleration Solution v2.0 Development
+(#4919)](https://github.sec.samsung.net/STAR/nnfw/issues/4919).  All WGs will work together to
+achieve the goal of _nnfw_ project, but each WG will define its own tasks and milestones, set its
+own sprints, and conduct its tasks.  All WGs will sync up through github (note that github is our
+primary communication channel, and thus using github for communication is highly recommended) and
+on/off-line meetings.
+
+Current WGs based on the major topics in
+[#4919](https://github.sec.samsung.net/STAR/nnfw/issues/4919) and their root issue links are as
+follows:
+
+1. Runtime WG
+    - Tasks
+      + Runtime improvement
+      + Heterogeneous computing support
+      + Runtime API
+    - Members
+      + Hanjoung Lee(@wateret), Hyeongseok Oh(@hseok82-oh), Chunseok Lee(@chunseok-lee), 
+        Yongseop Kim(@YongseopKim), Jiseob Jang(@jiseob-jang), Sanggyu Lee(@sg5-lee), 
+        Seongwoo Chae(@sw4670-chae), Sung-Jae Lee(@sj925-lee)
+      + Dilshodzhon Poshshoev(@d-poshshoev), Efimov Alexander(@a-efimov), 
+        Pavel Ilyutchenko(@p-iliutchenk)
+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
+      + Sanggyu Lee(@sg5-lee), Hyeongseok Oh(@hseok82-oh), Cheongyo Bahk(@ch-bahk), 
+        Hyun Sik Yoon(@hyunsik-yoon), Seok NamKoong(@sk-namkoong)
+      + Vladimir Plazun(@v-plazun), Sergei Barannikov(@s-barannikov)
+3. Kernel Optimization WG
+    - Tasks
+      + NN model analysis
+      + NN operator analysis
+      + Kernel implementation optimization
+    - Members
+      + Chunseok Lee(@chunseok-lee), Jiyoung Yun(@jy910-yun), Jiseob Jang(@jiseob-jang),
+        SaeHie Park(@seanshpark)
+      + Andrey Shedko(@a-shedko), Sergei Barannikov(@s-barannikov)
+
+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), 
+        SaeHie Park(@seanshpark)
+      + Pavel Ilyutchenko(@p-iliutchenk), Sergei Barannikov(@s-barannikov) , Ivan Vagin(@ivan-vagin)
