At work today, I wrote "we have several XXs. We should consolidate on one XX."
A colleague corrected it to consolidate into.
Which is correct?
I'm English and my colleague is American, if that makes a difference. Googlefight ranks them as about equal.
UPDATE
The actual XX is fairly technical and obscure so I'll use algorithm as a stand-in.
We use several algorithms for calculating the score.
–several paragraphs later–
We should consolidate on a single algorithm.
The separation between the problem statement and the solution leads me to believe that skipping the preposition won't work.
Best Answer
Is there confusion between consolidation and standardisation?
Consolidation combines or joins several things together into one solid thing.
Standardisation chooses one of several things and makes everyone use that one unchanged thing. Use of the other (now non-standard) things is then discontinued.
Perhaps "standardise on a single new† algorithm".
†substitute "composite", "consolidated" for "new" according to needs or taste.
