Big 3 of consulting: McKinsey, BCG, Bain - These are all strategy only.

Accenture was the consulting arm of Arther Anderson which was one of the Big 5 of accounting (Enron brought them down.)

Accenture is known for implementation/technology/strategy. Along with Deliotte, CapGemini, Booz, etc. These firms differentiate themselves with implementation from the Big 3 that are strategy only.

Management consulting is very different than technology consulting. Accenture, IBM, Deloitte, CapGemini: these are the kind of firms that compete against each other for enterprise tech projects.
