Formal words for “beside” and “in the best way”

Question

To translate a text, I wrote:

Today, the success of products and organizations largely depends on knowledge and innovation. The most successful organizations are those that use these assets beside the social capital in the best way.

I am not satisfied with "in the best way" and "beside", though don't know much other way to mention them.

I request for more alternative and formal ways to say "use something ... beside something else..." and "to use something in best way"...

By beside here I means something like "in conjunction with"..

I am thinking of

The most successful organizations are those that use these assets alongside social capital in an efficient way.

Answer 1

I suggest together with or along with

I would pull the best forward, you can then omit way

that make the best use of these assets together with social capital

or use optimal

that make optimal use of these assets together with social capital

while you could use optimally at the end of the sentence it feels rather clumsy.
