Top 7 Best IT Consulting Firms | 2017 Ranking | Best IT Consulting Companies & IT Consulting Services


Finding the Top IT Consulting Firms

IT consulting firms are companies that advise organizations on how to use information technology (IT) in the best way to achieve their business goals.

In addition to just providing counsel and recommendations, these IT consultancy firms often also deploy and administer IT systems for their clients, which is also known as outsourcing.

It is critical that companies looking to hire an IT consultancy carefully weigh their options before selecting a firm to work with. Using the help of a consultant can be a major investment for a company, but it can also have major rewards.

To help determine the following IT consulting firm ranking, the below review provides a comprehensive overview of the services, history, and reputations of the top IT consulting firms in the country.

Differences Between the Types of IT Consultancies

The consulting field encompasses a broad range of companies, often with a significant amount of overlap between the different types.

The two main types of consultancies that report to senior management within companies are IT consulting and management/strategy consulting.

IT Consulting

IT consulting companies solve problems with technology, like how to keep accurate records of all past clients. Management/strategy consulting firms solve broader business problems, like figuring out how to stop a decline in profitability in a certain department.

When you drill deeper into the IT consulting companies specifically, you see two more categories: IT management consulting and IT strategy consulting.

Though the exact definition of these two areas are debated, IT management consulting is generally known as the practice of analyzing the value creation chain in technology processes and determining how they can be effectively optimized for employees and customers.

IT strategy consulting fits into IT management consulting and can be explained as helping companies reduce costs, optimize business processes, and reform products and services by means of IT.

Why Companies Use IT Consultants

Before evaluating different IT consulting firms, it’s important to understand why companies need to hire these consultancies in the first place.

An Outside Perspective

When making tough decisions that will affect the future of their company, executives often need an outside perspective to make a truly informed choice.

An objective recommendation from an IT consulting company that is free of other motives helps them see the big picture without intrinsic biases.

Those who criticize the use of IT consultancies argue that they are selling insights that are common sense – however, sometimes leaders are so close to the company that they miss the obvious answer to their issue.

To Utilize Industry or Sector Best Practices

Since technology consulting firms work with various leading companies in the same sector – like retail or software – they often deal with multiple companies that have the same issues.

This leads them to experience the various best practices that lead to the ideal outcome for each company.

Consultancies will often preserve this information in white papers or other resources, but, more commonly, the knowledge of top IT consultants is the most beneficial for companies trying to solve a sector issue.

The specialized expertise that IT consultants can provide is often unmatched by internal executives since they only have in-house knowledge to support their actions.

Staff, Skill Set, and Analytic Augmentation

Sometimes, IT consulting firms are brought in simply because a company doesn’t have enough of something they need to get the job done.

This could be a lack of staff – a company may have experienced a sudden expansion that requires more people to take on the capacity of work or it’s facing a large project that will necessitate temporary workers. This could also encompass skill sets.

Recommendations that consulting companies make do little good if they can’t be carried out because employees don’t have the necessary skills or abilities, so, often, IT consulting companies will take on training employees in new areas.

Finally, the need for complex business analytics has risen with the increasingly data-driven business environment of the last several years.

IT consulting firms usually have access to more resources needed for data mining and market research than other companies do.

Accenture Review

Accenture is a multiservice consulting firm focused on IT consulting but that also includes several other service areas. It is headquartered in Dublin, Ireland, though much of its operations occur in New York.

Notably, Accenture is the world’s largest IT consulting firm as measured by revenue. It is a global company, serving clients in more than 120 countries and boasting more than 5,000 patents and patent pending applications.

Accenture’s specific IT arm was opened in January 2003 and focuses on implementation delivery and research of technology solutions. It works with virtually any sector, from aerospace to entertainment.

Key Factors That Led to Our Ranking of This as a Top IT Consulting Firm

Below, please find a detailed review of the specific factors that enabled us to include Accenture on our list of the best IT consulting companies this year.

Proactive Team-Building Approach

Accenture is continually seeking new team members, regardless of having a specific job opening or not.

It has also been known to size up potential recruits before they’ve even finished college and is always looking for the best and brightest in a given field to come bring their skills to consulting.

In addition to typical recruiting tactics, Accenture also holds a student empowerment program where Accenture targets scholars in the business and technology fields, from their sophomore to senior years of college.

Women's Programs & Initiatives

As one of the top IT consulting companies, Accenture maintains a strong commitment to empowering and supporting women in the workplace.

Their goal is to attract, retain, and advance their female employees, supporting diversity and corporate success. This is accomplished through a series of women's programs and initiatives, which include:

  • Women's Mentoring Programs
  • Accenture Women's Network
  • Delivering Success Forums
  • Employee Resource Groups

Summary of Accenture IT Consulting Reviews

Most reviews of IT consulting companies on the web are in agreement that Accenture’s services are high quality, but, due to this, its rates are extremely high. 

This is why most of Accenture’s clients are large, well-known brands who can afford these rates. In this regard, Accenture is much less likely to work with anyone in the SMB space.

For a large company, reviewers cite that Accenture is fairly agile and can adapt quickly and get to know a client’s business and processes extremely well.

Though Accenture hires top-notch people from respected universities and companies, some reviewers cite that there is a large drop in the quality of the work if a more junior-level person is handling the day-to-day aspects versus an executive.

Capgemini Review

Capgemini is one of the world’s largest management, outsourcing, and IT consulting firms, with over 190,000 employees in over 40 countries.

It is currently headquartered in Paris and is divided into four main disciplines: consulting services, technology services, outsourcing services, and local professional services (through Sogeti).

With global revenues of EUR 12.6 billion in 2016, Capgemini is one of the best IT consulting firms to consider partnering with.

Key Factors That Led to Our Ranking of This as a Top IT Consulting Firm

Below, please find a detailed review of the specific factors that enabled us to include Capgemini on our list of the best IT consulting companies this year.

Company Culture

One of the main draws for potential Capgemini employees is the culture. Since it is based in Europe instead of the US, hours are shorter and weekend/night shifts are rare. The work-life balance is similar to working in-house.

Promotions and raises for IT consultants at Capgemini are determined by performance and the level of responsibility they are willing to take on.

The Collaborative Business Experience

A big part of Capgemini's success comes from what they call The Collaborative Business Experience. IT consulting services at Capgemini are created with collaboration at the forefront of each and every service. 

This best IT consultancy believes that true success comes from working closely alongside their clients to create a tailored approach. To achieve success through collaboration, Capgemini uses four dimensions of collaboration:

  • Targeting Value: Defining specific goals and creating targets for individual projects
  • Mitigating Risk: Understanding stakes of each initiative and reducing challenges 
  • Optimizing Capabilities: Providing necessary support and knowledge to empower clients
  • Aligning the Organization: Creating lasting value through understanding and eliminating potential inhibitors

Summary of IT Consulting Reviews

As one of the top IT consulting firms, Capgemini offers many assets to fill the holes in its client organizations.

However, reviewers note that often, their accounts get transferred between several different IT consultants which creates a loss of knowledge transfer and continuity.

At the same time,  reviewers do note that Capgemini is relatively flexible about switching between projects, and its level of expertise in its field is high.

Cognizant Technology Solutions Review

Cognizant is an IT consulting and business process outsourcing company headquartered in New Jersey.

Cognizant was named one of Fortune's Most Admired Companies for eight years in a row, making them one of the best IT consulting firms in the nation.

Key Factors That Led to Our Ranking of This as a Top IT Consulting Firm

Below, please find a detailed review of the specific factors that enabled us to include Cognizant on our list of the best IT consulting companies this year.

  • Client-First Mindset
  • Two-in-a-Box Relationship Model

IBM Global Technology Services Review

IBM Global Services encompasses a broad range of IT consulting and services, including mobility, networking, resiliency, technical support, outsourcing, and security. These are split between two divisions: its Technology Services and Business Services.

In recent years, IBM Global Technology Services has drastically cut its India-based workforce as it has shifted away from the outsourced work model and has moved to more high-level IT solutions.

The move to more cloud-based and less software-based IT solutions means there is less of a need for companies to build their own software. Before this, IBM Global Technology Services was the largest IT employer in India.

Key Factors That Led to Our Ranking of This as a Top IT Consulting Firm

Corporate Reponsibility

As a global leader among IT consultancies, IBM takes a proactive approach towards corporate responsibility. This is done with innovative technology, continuous transformation, and sustainable change. 

Some core tenets of IBM's approach to corporate responsibility include:

  • Supporting & improving local communities
  • Investing in the personal & professsional growth of employees
  • A commitment to environmental protection
  • Requiring social & environmental responsibility through their supply chain
  • Comprehensive & rigorous corporate governance

​The effects of these principles have been overwhelmingly positive. Since 2003, IBM employees have logged almost 20 million hours of community service in more than 120 countries.

This best IT consultancy has also delivered almost 2,000 Impact Grants to not-for-profit organizations, and has conserved 7 million MWh of electricity through their internal energy conservation projects.

IBM Cloud Advisors

One of the top IT consulting services found through IBM is the availability of their IBM Cloud Advisors.

These IT hybrid cloud computing experts can work alongside clients to identify and implement individualized cloud-based solutions, with over 4,300 successful implementations to date. 

Potential clients can chat with an advisor through instant messaging, or they can choose to call to speak directly with someone about their unique IT needs.

Summary of IT Consulting Reviews

Despite IBM Global Technology Services being one of the largest IT consulting firms, there aren’t many reviews of its services online.

However, IBM has been known as a legacy and established brand for decades, and its consulting arm benefits from carrying this prestigious name.

As the shift away from technology outsourcing continues, many believe IBM is scrambling to keep up with the shift  to cloud-based technologies and could lag behind more agile and lean IT consultancy firms.

KPMG Review

KPMG is an American professional services firm and a member of the “Big Four” of auditors. It is the fastest-growing Big Four firm, citing its investments in employees and key services as being catalysts of its growth.

Summary of IT Consulting Reviews

KPMG isn’t as well known for IT consulting as some of the other IT consulting firms in this ranking. It’s mostly known as an auditing and tax firm, though a surprising amount of its business is dedicated to its advisory arm.

Clients that have worked with KPMG do note that it does a great job at mixing both strategy and implementation into its recommendations and takes a clear, measured approach when advising on IT services.

Tata Consultancy Services (TCS) Review

In contrast to KPMG, Tata Consultancy Services is primarily an IT consulting and technology services firm.

Founded in 1968, it was a key player in Y2K software preparations, created the factory model for conversion and developing tools to help with integration and conversion.

TCS became a publicly-traded company in 2004, and, in 2011, it broke into the cloud-based services market, opening up to small and medium-sized enterprises.

TCS ranked sixth in Forbes’ “Most Innovative Companies” list, making it the highest-ranked IT consulting company and the first Indian company to be included.

Key Factors That Led to Our Ranking of This as a Top IT Consulting Firm

Below, please find a detailed review of the specific factors that enabled us to include TCS on our list of the best IT consulting companies this year.

Diverse Service Lines

Part of becoming one of the best IT consulting firms comes from offering a wide array of IT consulting services.

While their Consulting & Systems Integration services provide the best value for IT consulting services, TCS offers a few other notable service lines for clients to consider utilizing.

TCS’s service lines are organized under the following categories:

  • Assurance Services 
  • Business Operations
  • Product Engineering
  • Technology Operations

​Global Top Employer

As a global IT consulting firm, TCS employes over 362,000 associates across 45 different countries.

These associates represent 129 unique nationalities. Additionally, with 33.4% women employees, TCS is one of the largest employers of women.

As a result, TCS has been named a Global Top Employer by the Top Employers Institute. Only seven other organizations worldwide have been awarded this status, marking a significant commitment by TCS towards diversity, inclusion, and talent.

Human Resource Recognition

In 2016, TCS was also given exceptional ratings by the Top Employers Institute based on nine core Human Resource factors

  • Talent Strategy
  • Workforce Planning
  • On-Boarding
  • Learning & Development
  • Performance Management
  • Leadership Development
  • Career & Succession Management
  • Compensation & Benefits
  • Company Culture

Summary of IT Consulting Reviews

As with many of the largest IT consulting firms, reviewers cite that account management can be erratic across the company depending on whom you work with most closely.

TCS employs a large amount of contractors, meaning that some people who work with TCS find that getting these temporary employees up to speed on their business can be tedious.

However,  reviewers do note that TCS’s technical knowledge is par to none, and that this is an advantage to its business.
