Whenever you think about Accenture orgnization structure you should think on a matrix one. Rows are Services Lines (what services Accenture provide) and columns are Industries that Accenture serve.
People inside Accenture belongs to an Industry or Market Unit (generally Products, Resources, Communications & High Tech, Financial Services, Government and others depending the location). Inside a Market Unit or Industry People is subdivided into Service Lines since each Market Unit works separately.
Business Consulting for example has various Service Lines such as:
Supply Chain Management
Strategy & Business Architecture
