A quick clarification before anything else. I draw a distinction between a strategic consultant and a strategy consultant. The latter is a subset of the former. A strategy consultant works within a defined discipline. A strategic consultant looks at the broader question of what needs to be done, not how to do it. That also separates them from tactical consultants, who largely function as an additional pair of hands.
Like their tactical counterparts, strategic consultants bring deep knowledge and expertise in their field. But the buyers of strategic consulting are typically found further up the organisation: department heads, non-executive directors, senior management. And the higher up the organisation you go, the more the work demands beyond expertise alone.
Senior buyers are rarely dealing with a single clean problem. Alongside their domain responsibilities they are navigating internal power struggles, turf wars, budget battles, and the challenge of driving performance inside structures that have not kept pace with what the organisation actually needs. Walking in with a textbook answer is rarely enough. Understanding the environment your buyer is operating in is at least as important as understanding the subject matter itself.
Over many years and many assignments I have come to believe that three traits, above all others, separate a truly strategic consultant from a knowledgeable one.
The first is understanding behavioural tendencies. Every individual has an innate predisposition shaped by their history, their experiences, and the pressures currently bearing down on them. A senior buyer who appears resistant to change may simply be protecting something fragile. One who pushes for speed may be working against a deadline you have not been told about. Reading these tendencies accurately, rather than taking behaviour at face value, allows you to frame your work in a way that the buyer can actually act on.
The second is understanding environmental factors. No organisation exists in isolation and no intervention lands in a vacuum. The regulatory climate, the competitive landscape, the internal culture, the history of previous initiatives that succeeded or failed, all of these shape what is possible and what will be resisted. A strategic consultant who ignores the environment and focuses only on the theoretical solution will find their recommendations sitting in a drawer.
The third is understanding personal interactions. At senior levels, almost everything moves through relationships. Who trusts whom, who has influence beyond their title, where the informal power actually sits. A recommendation that travels through the right relationship lands differently than one delivered through the formal hierarchy. Knowing how to navigate those dynamics, without becoming political yourself, is one of the harder skills to develop and one of the most valuable ones to have.
Expertise gets you in the room. These three traits determine what you can actually achieve once you are there.
