How can one say it 'like it is'?

Without coming across as harsh or judgemental?

Having redeeming qualities in one area does not mean that one is a success or even adequate in others. Is it enough to get the basics right, but fail at the key things one was charged with doing?

I'm also learning that if you don't want to face a 'difficult situation' down the road then you need to speak up at the start or face the consequences.
