He may use your in-competencies to demonstrate His Authority

 Daniel 4:17

(17) "This decision is by the decree of the watchers,
And the sentence by the word of the holy ones,
In order that the living may know
That the Most High rules in the kingdom of men,
Gives it to whomever He will,
And sets over it the lowest of men."

As Christian business professionals  

God may use your in-efficiencies

to demonstrate His possibilities  ,

God may use your in-adequacies

to demonstrate his Majesty

He may use your in-competencies 

to demonstrate His Authority

So those who makes themselves Lowly will be lifted up'

make yourself humble and you are in direct  line of God using you for His GLory, His Prestige, His Honor, His Praise!
