A shidduch often begins with a recommendation from family members, friends or others who see matchmaking as a mitzvah, or commandment.
If the shidduch works out then the couple inform the shadchan of its success.
This is taken as an instruction for Jewish parents to weigh their child's opinion in the balance during an arranged marriage.
Regardless of whether proper procedure is followed, this is not the end of the decision - it is believed by Jews that the final say belongs to God, who may have different plans (compare with the match of Jacob and Leah).
Eliezer then went with Rebekah to her family and appealed to them for permission to take Rebekah back with him to be Isaac's wife.
Once this permission was granted, Rebekah joined Eliezer on the road home to Isaac.
Also, the decision as to whether or not the mate is good can be made with the emotional boundary of the shadchan who, if so desired by the couple, can call and talk to either side in the beginning stages of the dating to iron out issues that can crop up during the dating process.
Usually as the couple see more of each other the shadchan backs away and lets the couple manage it themselves.
Some engage in it as a profession and charge a fee for their services.

Those who support marriage by shidduch believe that it complies with traditional Judaism's outlook on Tzeniut, modest behaviour in relations between men and women, and prevents promiscuity.
It may also be helpful in small Jewish communities where meeting prospective marriage partners is limited, and this gives them access to a broader spectrum of potential candidates.
The number of bashows prior to announcing an engagement varies, as some have many bashows while others have as few as one, which is typical among the children of Hasidic Rebbes.
