Avoid treating simultaneous AI investment and slower growth as proof of causation.
Technology Unit Weighs
Deloitte’s consulting growth slowed as its technology unit lagged and investment in artificial intelligence rose. [2] The Financial Times separately reported that Deloitte’s technology consulting arm curbed the firm’s global revenue growth. [1] Together, the reports identify the technology consulting operation as a drag on Deloitte’s wider growth performance. [1][2] Traders Union’s report describes consulting growth as slowing while both the lagging technology unit and increased AI investment feature in its account. [2]
What it means
The reports place Deloitte’s technology consulting arm at the center of weaker consulting and global revenue growth, while the second account also highlights rising AI investment. That combination does not establish whether AI spending caused the slowdown; it only shows that the two appear in the same report. Neither source excerpt supplies a rival consultancy, benchmark, growth rate, or investment figure, so a competitive comparison is not possible. What the sources don't address: whether Deloitte expects AI investment to improve the technology unit’s growth.
The reports show why AI investment and AI-related business performance should be evaluated separately. Practitioners need spending, revenue, productivity, and adoption measures before concluding that higher investment is producing commercial gains.
