Intro: Why Partner with Management Consulting Firms?

In the business world, the word “consultants” can bring up mixed feelings. On one side of the spectrum are those business professionals that feel that “consultants” are simply high-priced “experts” who bring little value to an organization.

On the other hand, there are business owners and professionals that feel a consultant is someone who can bring new solutions and ways of doing things that can create true value if implemented.

So, who’s correct? In short, both. In terms of management consulting specifically, it can be an excellent resource for a business, but only if you’re working with one of the best management consultant firms. 

For the most successful consultant engagements, it’s essential for businesses to have a clear idea of their goals and the role they want business management consulting firms to take on, as well as how they will measure success.

A.T. Kearney Review

A.T. Kearney has been a reputable firm delivering trusted advisors since 1926. A partner-owned firm, A.T. Kearney has offices in more than 40 countries with over 3,600 employees.

A.T. Kearney provides management consulting services to more than three-quarters of the Fortune Global 500 as well as some of the world’s most influential governmental and non-profit organizations.

A.T. Kearney ReviewKey Factors That Enabled This to Rank as One of the Top Management Consulting Firms

Global Presence

Many of today’s top corporations don’t operate in just one country.

They likely have offices, interests, and projects in multiple countries, which makes it important that they have access to a management consulting firm that understands a globally-driven marketplace.

A.T. Kearney is present in over 40 countries across the globe. This is valuable for any organization that needs to maintain an understanding of the global market.

As a further example of their global outreach, the Global Business Policy Council (GBPC) is a specialist unit of A.T. Kearney, created and operated with the goal of helping leaders prepare for the future.

Diversity & Inclusion

As one of the top management consulting firms, A.T. Kearney upholds the belief that key to its success and its ability to provide value to clients is its focus on diversity and inclusion.

All employees have access to equal opportunities, consultants are empowered to be themselves, and teams include people from unique backgrounds, providing clients with diverse skill sets.

A.T. Kearney has long been recognized by leading media outlets for its dedication to diversity and inclusion, setting standards across the industry.

Rating Summary

As one of the best management consulting firms, A.T. Kearney has maintained a strong reputation for professionalism, inclusivity, and consulting expertise.

Unfortunately, while the firm’s website is certainly visually appealing and exudes a great sense of energy, there is no way for potential clients to view proof of this expertise via the firm’s past clients and successes.

By publishing case studies, A.T. Kearney could not only provide an in-depth look at their consulting strategies, but the firm would also improve the way their value is communicated, improving their ranking from a 3 to a 5.

Accenture Review

Accenture is an international professional services company, providing management consulting as well as strategy, digital, and technology operations.

Key Factors That Led Us to Rank This as One of the Top Management Consulting Firms


Value-creating management consulting services and relationships should be built on a foundation of innovation. That sense of innovation and forward-thinking transformation is based on research and insight.

It’s with that in mind that Accenture regularly commissions and publishes new research and ideas on topics relating to the industries it serves.

This means that not only do clients have access to critical research, but this data is used as a basis to create valuable management consulting services.

Content and research are compiled and shared not only as articles and case studies, but also as Slideshare presentations and even YouTube content.

Transformative Approach

This top management consulting firm enters into client engagements with a unique approach, seeing change as being achievable by anyone.

Instead of gradual, incremental changes, Accenture empowers consultants to believe in bold moves and difficult decisions, creating complete organizational transformation through technology and innovation.

According to Accenture, the result of the transformative approach has been things like $1 billion in savings for Mondelez and 350 percent growth for Uniqlo, among many other tremendous success stories.

Rating Summary

As one of the best management consulting firms, Accenture demonstrates a keen focus on providing publicly available, expert research.

Accenture’s research is frequently quoted in the media, and website visitors can easily access articles and reports on a variety of topics, like Blockchain, Internet of Things, and Artificial Intelligence.

This combination of in-depth expertise and transparency is rarely seen among management consulting firms, giving Accenture a solid rating of 5.

Our review found that the firm is both forthcoming and detailed when discussing their values, social impact, press coverage, and case studies, building a strong foundation for trust between consultants and clients.

Deloitte Consulting Review

Ernst & Young Review

Ernst & Young (EY) has a history that dates back to the early 1900s, growing to become a global force among management consulting firms.

Globally, there are 231,000 EY employees, with this top strategy consulting firm operating in 28 regions around the world.

Although the firm continues to be ranked highly by media outlets, our review found that businesses could be http://www.ey.com/us/en/about-us/our-global-approach/2020-vision_our-global-approachmuch better served by choosing another one of the top management consulting firms.

See below for an in-depth overview of why EY earned a 1 rating, and what the firm can do to improve their ranking.

Rating Summary

Despite the positive accolades that EY is known for, the firm has had its fair share of legal woes that bring the firm’s ethics into serious question.

In 2015, EY settled for $10 million in a New York lawsuit accusing the firm of assisting Lehman Brothers deceive investors in their audits. One year later, EY settled for $9.3 million due to relationships with clients that compromised the ability of auditors to remain impartial.

The firm has also been under criminal investigation by the IRS regarding the promotion of illegal tax shelters, which should make potential clients think twice before partnering with the firm.

Although EY is still highly regarded as an expert management consulting firm, these legal issues create a significant difference between EY and competing management consultant firms.

Looking forward to the future, the best way for EY to improve their rankings is to approach these issues with the goal of restructuring the way that their values are enforced amongst consultants.   

Although the firm does publicly advertise their values, the presence of so many lawsuits could mean that the firm is having difficulty following through.

Throughout the years, mergers and acquisitions have allowed Oliver Wyman to thrive and grow while maintaining a similar purpose and set of values.

Oliver Wyman defines its purpose as bringing exceptional people together to create value, through the implementation of lasting contributions not just to clients but also to industries and societies.

Key Factors That Enabled This to Rank as One of the Top Management Consulting Companies


One thing that makes Oliver Wyman unique from many other management consulting firms is its dedication to turning every client engagement into a true partnership.

For this top management consulting firm, partnership can only succeed after completely understanding all aspects of a client’s business.

  • Automotive
  • Aviation, aerospace, & defense

PricewaterhouseCoopers (PwC) Review

PricewaterhouseCoopers (PwC) was initially started as a London-based accounting practice more than 100 years ago, making them one of the oldest management consulting firms on our list.

Over time, it has grown to include tax, audit, assurance, and business consulting services across a global network of 158 countries, with more than 236,000 talented professionals.

PwC partners with clients to help them solve complex challenges and identify new possibilities and opportunities across many diverse industries and sectors.

Key Factors That Led Us to Rank This as a Top Management Consulting Firm

Customer-Based Focus

Without a partnership with PwC as a management consulting firm, many businesses may suffer and not be able to achieve their objectives because they will forget a key element: the customer.

One of the service areas offered by PwC involves helping clients gain a comprehensive understanding of their customer. That understanding includes the underlying needs of the customer and the outcomes he or she is searching for.

Ultimately, a partnership with PwC helps build customer strategies and distinctive experiences based on a firm foundation of analytics and experience design.

No matter what, this top management consulting firm maintains the importance of meeting goals while staying true to the core brand values and promise of the client’s organization.

PricewaterhouseCoopers (PwC) Review

Cybersecurity & Privacy

One of the more unique aspects of the services available from PwC is cybersecurity and privacy, which are constantly growing concerns for most, if not all, organizations around the world.

PwC management consultants can work with clients to uncover the newest technologies and methodologies that will allow them to remain competitive and prepared for the current environment as well as the threats and challenges of the future.

As one of the best business management consulting firms, PwC strives to offer the broadest view of cybersecurity and privacy, balancing competing issues and concerns that make up these complex business consulting services.

Rating Summary

With over a century in business, PwC is a powerful force among management consulting firms. Although the firm is consistently ranked highly, PwC currently finds itself amidst a mess of legal issues.

An ongoing 2016 lawsuit accuses PwC of age discrimination in the hiring process, accusing the firm of saving entry-level positions exclusively for young college graduates.

PwC is still a top-ranked management consulting firm for its consulting expertise and client-based focus, but the firm ultimately receives a 3 for a questionable internal culture—a topic which has yet to be addressed by the firm itself.

While there isn’t much that PwC can do until the lawsuit is settled, discussing the topic with transparency could certainly boost the firm to a 5 rating.

The Boston Consulting Group Review

The Boston Consulting Group (BCG) is a global consulting firm that began in 1963 with the mission of helping organizations develop and cultivate a long-term competitive advantage.

While the firm has since grown and evolved, central to everything it does is a dedication to the original core values put in place more than 50 years ago.

All client engagements are guided by the desire to create value and insights that contribute to gaining a competitive advantage.

Key Factors That Led to Our Ranking of This as One of the Best Management Consulting Firms

Smart Simplicity

One of the core components of the management consulting offered by BCG is called “Smart Simplicity”, which works to minimize and efficiently manage the growing number of requirements that companies need to meet.

Businesses are increasingly pressured into creating new systems to address these requirements, leading to vertical layers, decision approvals, and increased operations that can have performance ramifications.

The Smart Simplicity approach strives to address these complexities in a smarter and more streamlined manner, improving performance as a result.

Four Approaches

Another aspect of capabilities delivered by BCG centers on something called the Four Approaches to Business Model Innovation, which is yet another signature offering from this top management consulting firm.

The Four Approaches looks at business model innovation with the belief that not all innovation is the same, effectively catering their approach to the unique objectives of each company:

  • The Reinventor: Designed as a response to fundamental industry challenge, such as a new regulation
  • The Adapter: Aimed at addressing change without causing a disruption to core business
  • The Maverick: Centered on startups and designed for businesses that are completely changing their industry
  • The Adventurer: Seeks to expand the footprint of a business by moving into new areas

Rating Summary

Where BCG truly excels is at their multi-faceted, in-depth approach to management consulting.

No two business are the same, and with the Four Approaches to Business Model Innovation, new clients can rest assured that BCG can take a customized approach to their unique needs and goals.

When evaluating the firm for a rating of 5, we also considered how current and former consultants view the company as a whole.

Based on consistently positive reviews from employees, BCG has recently earned recognition as the third best place to work in 2017, putting BCG in the company of the best management consulting firms.

This combination is incredibly rare, providing clients with a unique advantage and allowing The Brattle Group to be ranked among the best management consulting firms.

Rating Summary

Based on their commitment to academia, expert consultancy, and impressive list of clients, The Brattle Group has earned a 5 rating on our list of the top business consulting companies.

Conclusion – Top Management Consulting Firms

The business economy and environment are increasingly complex, wrought with challenges, overwhelmed with competition, and difficult to navigate.

Many businesses find it difficult to gain or regain their footing amidst the uncertainty, turmoil, and globalized marketplace, which is often why they turn to business management companies.

When looking for the best management consulting firms, it’s not just general consulting experience that’s important—it’s also deep industry knowledge and expertise.

Management consulting companies should be able to hone in on key insights and research, create plans and strategies, and then bring those to fruition in a way that’s sustainable and realistic.

A management consulting firm should employ a team of the very best business experts who can integrate experience, data, and holistic understanding to create long-term solutions and value.
