As mentioned before, almost all consultants are A-type personalities with enough ambition to last a lifetime. But what really distinguishes a good consultant from a great one is the ability to not only focus on the tasks at hand, but also to think critically about the work. For example, your client may be asking you to find cost savings in a supply chain, but first, try to understand why this is critical to the business. Are profits declining? Is the competition lowering product prices, forcing your client to compete? Knowing how to think this way will help you develop better insights and solutions for your client. Try spending a little extra time thinking through your task before jumping in, interpret the numbers you’re crunching (don’t just be an Excel monkey!), and challenge your manager’s requests (when appropriate, of course).
