There are many reasons to hatch eggs in Pokémon Brilliant Diamond and Shining Pearl. And if you want the strongest Pokémon, you need high IVs. The math behind IVs is basically just an odds game. The more perfect IVs you have in your parent monsters, the more likely they are to be passed on. The process is tedious for many players, but a bunch of players want to have the fastest and most efficient breeding process they can.
Getting a Ditto with 6 high Individual Values will be the first step you need to engage to breed monsters faster. Ditto can breed with any Pokemon and any gender, with the exception of Legendaries.
You will also want to find the Destiny Knot to help pass on IVs, as it passes on 5 out of 6 IVs from between two parents. You can obtain the Destiny Knot on Route 224, accessed by the blocked area of Victory Road. Give the Knot to your high IV Ditto and leave it at the Pokemon Nursery in Solaceon Town.
The Everstone is the third and final piece of kit you need. This item locks the Nature of a bred Pokémon into the parent. You can get the Everstone either by trading a Medicham for the Haunter found in SNowpoint City, which is the easiest way. There’s also the RNG=dependent method of digging for it via the Grand Underground. There are some reports that Wild Geodude can also hold it, but this has a very small chance of working. Go with the first two methods.
