  The professional services industry (legal, accounting, consulting,
architectural services{\ldots}) employs an important share of the active
population in mature countries. However, after decades of undisputed growth,
the sector appears to be at a turning point in certain geographies. This
article therefore proposes a simple framework to help diagnose where growth
opportunities (if any) may lie.When applied to the US economic context, the
model indicates that at a macro-economic national level the sector should
stall, which concurs with the trend observed over the past decade. However, it
also highlights that a few industrial sectors (e.g. the US beverage industry)
still offer pockets of growth for a variety of professional expertises.
Replicating and fine-tuning those findings could be interesting for
practitioners to steer their marketing and business development efforts. On the
other hand, the quantitative framework presented in this study could pave the
way for future research in the academic community.
