PwC - PricewaterhouseCoopers

Originally founded in 1854 under the name ‘Coopers and Lybrand’, PwC, or PricewaterhouseCoopers is ranked as the second-largest professional services network in the world, and is part of one of the ‘Big Four’ accounting firms. With an annual revenue in 2017 of around $37.68 billion, it is estimated that about a third of this revenue was from their consulting and advisory services. It operates worldwide and offers a range of consulting services in areas such as IT, technology, actuaries, human resources.

In the 90s, PwC’s consulting services fell under what they termed ‘Management Consulting Services’ or MCS. It was largely profitable due to its worldwide use of Enterprise Resource Planning systems (ERPs), which is a business management software. Eventually, MCS was renamed as PwC Consulting, and it was later announced that it would run as a separate entity to the rest of the company.

PwC’s ‘advisory’ or management consulting services work with client organizations across various business functions, particularly in the implementation of mergers and acquisitions, customer relationship management, human resource transformation, enterprise strategy transformation, finance transformation and operations transformation. They own a large share of the global advisory market and have various areas of expertise in all the major industries, but have been known to do a considerable amount of consulting work in government, healthcare, oil & gas and financial markets.

On a global level, PwC’s management consulting services are rivaled by those of the other ‘Big Four’ firms i.e., EY, KPMG and Deloitte as these three firms offer comparable services and have similar structures.


Founded in 1953 as an accounting firm under the name Arthur Andersen, consulting used to be a division of the organization. Both accounting and business & technology consulting divisions of the company worked side-by-side until 1989. After this, Arthur Andersen and Andersen Consulting became independent entities. Headquartered in Dublin, much of the company’s operations currently occur in the USA.

Accenture is known for their technology and IT consulting services, among their other service offerings. The average consulting project’s at Accenture focus on cost-optimization, efficiency and operational management. Accenture, too, has numerous practice areas such as cloud migration, cybersecurity implementation, technology transformation, digital implementation, business process management etc.

In terms of industries where they operate, Accenture covers a broad range-from aerospace and automotive to capital markets to media, communications and technology. They have taken on a large number of projects in various industries, most notably tech-related client organizations, though they have expert consultants in many other industries too.

Founded in 1945, Deloitte has been the largest professional services network globally by revenue for several years. Deloitte, similar to many of the other ‘Big Four’, was founded as solely an accounting firm but developed a consulting arm in 1995 when the Deloitte & Touche Consulting Group was created. As of 2017, Deloitte’s annual revenue stood at $38.8 billion, of which the largest sum of money ($14.4 bn) came from their consulting and advisory service offerings.

Today, Deloitte’s management consulting is within the ‘Deloitte Consulting’ division. The branch is further divided into sectors of Human Capital, Strategy & Operations and Technology. The majority of management consulting projects are under S&O in several key areas of business functions which Deloitte offers consulting services for such as finance, mergers and acquisitions, supply chain and manufacturing operations, to name a few.

Deloitte specializes in offering tax consulting services and is a leader in the tax industry. It also has leading consulting practices in technology and human capital areas. Deloitte offers management consulting services in consumer industries as well as energy, resources, financial services, healthcare, technology and telecommunications, to name a few.

As with PwC, Deloitte’s largest competitors are the same due to the similarities they share in size, structure, service offerings and nature of projects they take on, though Deloitte as a firm has held the title of ‘largest’ by revenue for many years.
