IT specialization is provided as its own separately configurable category in this mod's calculations (along with all specializations of all zoning types).

However, this mod is targeted for realism, and will override (or be incompatible with) simple and unrealistic "gamey" mechanics. In the real world city policies don't reduce workforces by 30% while retaining the same outputs and tenancy requirements, and so they don't in the mod, either.

(This also goes for the effects of unique buildings that provide those - generally bizarre - gameplay changes).

If you're interested in that style of gameplay mechanism (which is perfectly fine! Realism-oriented payers are a minority of the player base, after all), then this mod probably won't work well with your playstyle.
