PMBOK 5th make difference between default/cause terminaison : "Control procurement includes capturing the necessary details for managing any early termination of the contracted work (for cause, convenience, or defaut) in accordance with the terminaison clause of the agreement".

But in another place in PMBOK, it is say "Early termination of a contract is a special case of procurement closure that can result from a mutual agreement by both parties, from the default of one party, or for convenience of the buyer if provided for in the contract". There no distinction form default/cause terminaison....

I found on the web "When the government terminates a contract for its convenience, whether the contract is commercial or noncommercial, it is called “Termination for Convenience.” When a noncommercial contract is terminated due to contractor fault, it is called “Termination for Default” and the termination of a commercial contract due to contractor fault is called “Termination for Cause".".... Is this last one the good explaination of the difference ?

Thanks
