In　a　trend　towards　digital　continuity,　model-based　systems　engineering　is　becoming　widely　adopted　for　the　design　of　complex　systems,　supporting　system　development　from　the　very　first　stages.　A　narrow　panel　of　methods　and　tools　are　available　on　the　market;　they　offer　different　scopes　and　approaches,　are　more　or　less　intuitive　to　follow,　and　are　sometimes　supported　by　tools.　Among　them,　the　Architecture　Analysis　&　Design　Integrated　Approach　(ARCADIA)　is　becoming　popular　and　is　gradually　spreading　in　different　industrial　fields　to　model　a　wide　variety　of　systems　at　different　stages　of　their　development　and　from　different　points　of　view.　It　is　implemented　using　an　open-source　tool　called　Capella.　Few　feedback　on　its　use　in　industrial　settings　have　been　published,　while　other　feedback　remains　confidential.　The　goal　of　this　paper　is　to　analyze　the　interests　and　limitations　of　ARCADIA/Capella.　To　reach　this　goal,　we　experimented　with　ARCADIA/Capella　in　several　projects　and　chose　one　to　explain　how　the　method　and　tool　proceeded.　In　addition,　we　conducted　a　survey　to　obtain　industrial　feedback.　As　a　result,　the　paper　gives　an　overview　of　the　relevance　of　ARCADIA/Capella　in　projects　and　of　its　usefulness,　effectiveness,　and　adaptability　in　modeling　different　types　of　systems.　It　also　provides　some　perspectives　for　the　evolution　of　the　method　and　the　tool　according　to　industrial　feedback.　©　2023　by　the　authors.
