Correctness
Correctness is tricky.
How do you know what the right answer is for everyone all the time? This is a difficult aspect of rightsumi to get right. The smallest details will make a solution right for one customer but entirely wrong for another.
To be correct, to be fundamentally the best, most right solution, is the goal. There can be multiple ultimately right and correct solutions, but very rarely will you be the most correct solution.
Correctness is a deep quality that cannot be faked. Don’t try.
Consider:
Is my solution the most correct, accurate and most importantly right solution for my customer? What would the more correct approach entail? Why am I not doing that?
