There aren’t definite ways to know for sure whether management consultancies get the right insights or not, except for them coming and revealing things from up and front. But then if you’re going carry that skepticism, you’ll have to doubt virtually anything and everything in the world. Can you do that? Can you doubt your parents, the society, your teachers? Perhaps not. So, I guess, there are a few things that you have to believe at their face value.

Coming back to the topic, I sure believe that top management consultancies do get the insights correct. They work with hundreds and thousands of clients—including some of the world’s leading brands. So, they are usually surrounded by extensive and reliable data. With the advanced tools and analytics that they use, they can easily throw in the chunk of that data and come up with helpful insights.

So, to answer your question, more often than not, management consultancies get the insights correct. Since I have worked in one of these, I can assure you that senior management is very sincere and you will get the right output.

Here are those top 5 you can rely on -

· Deloitte: Founded in 1845, it is one of the “Big 4” professional services companies. Its list of clients includes many big names, including Yamaha, Adobe and Dell. The company employs over a quarter-million employees across the world. Usually ranking among the best workplaces in the world, Deloitte was also the sponsor of 2012 London Olympics.

· Bridgespan Group: Although founded just in 2000, this is a non-profit organization that has seen a mammoth-like growth in recent times.

The decades of industry-existence, list of prestigious clients and large workforce alone outline the success stories of these top management consultancies.

Of course, there are many other names that are equally deserving to be on this “top management consultancies” list, including KPMG, A.T. Kearney, Bain & Co., and Ernst & Young.

Hope this answers your question.
