What Do Consulting Companies Do?

When you hire one of the top consulting firms, you’re seeking outside expertise, insight, and guidance to help in leading your company.

Consultants are brought in to help businesses improve performance and growth levels and find more efficient, effective methodologies and workflows. Business consulting firms can also help organizations save money.

There is any number of reasons you might seek out business consulting firms, and some of the more specific ones include:

  • While management consulting firms can be hired to help address general issues, such as increasing revenue, they also may be brought onboard to solve a very particular problem, or to help with an individual project.
  • If a business is experiencing people-related issues, consulting firms can help them in the hiring or managing their talent to maximize efficiency and move past hurdles. Consultants can bring value in the form of very deep, comprehensive knowledge and focus on one area or problem.
  • Implementing new technology has become a big reason businesses rely on consultant services. These firms can not only help businesses leverage new technology to solve problems, but they can also ensure the rollout goes as smoothly as possible.
  • Many businesses become stagnant from a lack of new ideas. Consultants can deliver a fresh, unique perspective that can allow their clients to identify new opportunities.

Of course, this list is hardly exhaustive, but it does give you a general idea of what top business consulting firms can help their clients achieve.

So, how do you narrow down the list of consulting firms and choose the right one for your needs?

Choosing Top Consulting Companies

This “detailed review and list of consulting firms” article is a long one, so here are a few areas of focus to help you narrow your search:

  • What are the reputations of consulting companies you’re considering? Reputation is a key factor when deciding on which company you’ll work with. Begin by asking colleagues and professional acquaintances if they have any experience with consulting companies. You can also do an online search to learn more about clients’ experiences with a particular firm and ask potential firms for a list of references.
  • Does the firm have a particular focus area or a certain realm of expertise? While some of the top consulting companies will have broad focus areas, it’s crucial to understand what a company does best and compare it to your needs.

  • What level of technology do they implement for clients? If you wanted to continue following the same outdated path, you wouldn’t likely need a consulting firm. You’re partnering with them because you want to find new ways of doing things, and many new methodologies rely on the integration of new technology. Before selecting from the top consulting firms, learn more about their view of technology, the digital world, and how they integrate these elements into their client solutions.
  • What size company are you comfortable working with? Some clients want a very large, multinational consulting company because they feel they’ll receive a broader experience and knowledge base, and they may require an emphasis on globalization to solve their unique challenges. On the other hand, some businesses may seek out consulting companies that are smaller and can deliver more personalized guidance for a niche industry or market.

To launch your search for the best management consulting firms, we created a list of consulting firms we think are among the best in the world.

We narrowed down the top 10 consulting firms into a more specific list covering the best 7. We’re offering in-depth reviews and information about each of these 7 top management consulting firms to provide you with a strong foundation to begin your search.

Bain employs a team of energetic, passionate people who delve into the specificities of each client’s needs, requirements, and goals. These are the people who treat the business of their clients as their own, and they create partnerships, rather than traditional client/consultant relationships.
