英语难句分析请问这一句怎么分析句子成分,例如主语谓语之类Only after the fundamental needs

Only after the fundamental needs of a corporation have been established can the basic objective for corporate programme be isolated without such a clearly defined objective the compaign will have little effect.
省略了一个that.这句话是以“Only”开头的倒装句.主语是 the basic objective for corporate progamme,谓语是be isolated...,only 引导的句子是一个条件状语从句.
without后面是without这个介词的宾语.
就是will前省略了一个that.
