Yes, it takes a long time for you to obtain installation. It took a whole year for my chapter to be installed. Installation doesn't happen instantly. For instance, the day you request to become a colony of ZTA doesn't mean the next day IO will come down to Install you. In fact, it won't be within the next month. ALL of the members have to really want to become a ZTA chapter. It doesn't take just 90%, 95%, or even 99% . . . it takes 110% effort and determination of the chapter in order to become a full chapter of ZTA. The responsibility to become a full ZTA cannot fall upon just a few people but every single member. Also, IO lets you be pretty much independent in recruiting, etc. They are not going to look over your shoulders to make sure you are doing EVERYTHING or EVERYTHING correctly. They want you do to do it on your own in the beginning so that you'll be able to do it later on so you won't have to have someone from IO looking over your shoulder all of the time.
