In Bosnia, they are comprised of two political entities who combined have ten cantons (gobols shoutout to
@LarryThePuntite ) whom have something local rule.
They were made to be a federal country but they are still much different to the pseudo federal system Somalia has in virtually every way. They are a federal nation with institutions are a proper Government. What Somalia did was take federalism and bastardize it. Like they said in the document "- or decentralization can occur at the behest of local politicians wanting power that the national politicans agree to concede" (paraphrasing)
As I said, Bosnia didn't choose to be federal and they still have many problems. But they had to after the Washington Agreement as the Serbs and Croats feared that the Bosniaks would concilidate power for themselves. They are held back by ethnic groups who don't trust eachother. Somalis are held back by politicans using qabiil to further their own interests. Getting rid of qabyalaad is much more easier than fixing inter-ethnic and inter-religious tensions. Especially with a centralised government that creates independent and strong institutions to sort out all the petty disputes in Somalia.
Example is Japan. They have clans with founders just like us but they long since sorted out any problems. And they transitioned from absolute Monarchy to a centralised government (with the Monarchy still in tact but largely ceremonial).
