My question might be dumb, But I'm very much interested to know what it meant.

One of my colleague is a very hard worker, he made a software that was required by his counter parts, e got a very awesome response from the other side.

But our manager wrote the below statement in his email.

About Sam, yes indeed I agree fully, and icing being this work done was done in whiff

I understood that this is a positive response for him, But I didn't understand the words like icing being this work and was done in whiff

Please let me know what does these mean.

Thanks
