The Compatibility Chart can only be done after both parties have already done their Birth Chart, as the calculations regarding the suitability of two individuals for partnerships have to be based on their precisely drawn up Birth Charts. Compatibility Charts were traditionally used for arranged marriages to ensure that the marriage is successful and satisfactory for both parties.
In the not too distant past when arranged marriages were the norm, the Compatibility Chart was always done before the marriage, and it was the most important (and often the only) way to see the opportunities as well as the potential for disharmony.
Today the Compatibility Chart is used before business partnerships are formed, for the exact same purpose. As pleasant and admirable “getting along” and “mutual respect” between friends are, if there is an inherent energetic imbalance, the business partnership is bound to fail financially.
For romantic relationship and marriage the Compatibility Chart acquired a new purpose, it is no longer exclusively done before the union is formed, it became the source of continuous guidance so necessary adjustments can be made in a marriage based on the understanding of the true nature of the spouses as Astrology can show the way where negative qualities are neutralized and positive qualities are enhanced for the benefit of both people.
