I predict that the next BIG4 consulting firm is going to be a networked global community of freelancers with skills, experience, certifications verified and lodged via blockchain technology.
Clients will choose larger teams via global platforms based on specific requirements, availability, location, previous client and co-worker feedback as well as cost but not brand.
Teams will be pre-assembled via AI driven algorithms that propose the best possible team composition based on individual profile based psychometric, aptitude and personality data.
These temporary teams will build individual tribe-like brands based on their achievements and how well they work with each other and their clients.
Payments will be based on agreed deliverables, milestones or other KPIs and transactions executed via smart contracts again via blockchain.
