The Best Leaders Know What They’re Bad At

The incomplete leader is not a failure in progress. They are the most commercially effective kind of leader there is, provided they know which pieces are missing and build around the gaps honestly. The leaders who have caused the most damage in agencies and marketing teams I have worked with were not the ones who lacked skills. They were the ones who lacked self-awareness about which skills they lacked.

This is not a soft leadership concept. It has direct commercial consequences. When a leader cannot see their own blind spots, those blind spots become organisational ones. Strategy drifts. Teams compensate in silence. Clients feel the wobble before anyone internally names it.

Why the Myth of the Complete Leader Persists

There is a version of leadership that gets celebrated in case studies, award entries, and conference keynotes. The decisive visionary. The one who had the answer in the room. The one who held the room. I have judged the Effie Awards and sat through enough of those narratives to know how polished they become in retrospect. The messy middle gets edited out. The moments of genuine uncertainty, the wrong calls, the pivots born from panic rather than strategy, all of it disappears into a clean arc.

The result is a leadership myth that is almost impossible to live up to, and quietly damaging when people try. Senior marketers spend energy performing completeness rather than building for it. They fill rooms with their own opinions because admitting they do not have one feels like weakness. They avoid hiring people who are better than them in specific areas because it threatens the narrative they have constructed about themselves.

I have done all of this. I am not writing from a position of having figured it out early. I am writing from the position of having learned it expensively.

What Happened When I Was Handed the Whiteboard Pen

Early in my career, I was in a brainstorm for Guinness at Cybercom. The founder had to step out for a client call and, without ceremony, handed me the whiteboard pen. I was not the most senior person who should have been holding it. My internal reaction was something close to panic. The thought that went through my head was direct: this is going to be difficult.

I did it anyway. But what I remember most clearly is not the session itself. It is the realisation that followed. I was incomplete. I did not have the founder’s instinct for the brand, his read of the room, his comfort with ambiguity in a creative setting. What I had was structure, a willingness to facilitate rather than perform, and enough commercial grounding to keep the conversation useful. That was enough for that moment. It would not have been enough for every moment.

That distinction matters. Incomplete leaders are not universally limited. They are specifically limited. And the ones who thrive are the ones who know the difference between the two.

The Commercial Case for Knowing Your Gaps

When I was brought in to turn around a loss-making agency, the brief was essentially: fix it. The business was haemorrhaging money, morale was low, and the structure had grown organically in ways that made no commercial sense. I had to make decisions quickly across areas where I had varying levels of expertise. Finance, operations, creative, client services, new business, all of it at once.

The areas where I moved fastest and most effectively were the ones where I knew my own capability well. The areas where I caused friction or slowed things down were the ones where I either overestimated my expertise or did not hire quickly enough to cover the gap. We moved the business from significant loss to meaningful profit, roughly a £1.5 million swing, but the path was not clean. Some of that mess was market conditions. Some of it was me not knowing what I did not know fast enough.

What I learned from that period is that the leaders who recovered fastest from bad calls were not the ones who made fewer bad calls. They were the ones who could identify the call as bad quickly, without the ego protection that slows the correction. That speed of honest self-assessment is a commercial skill, not a personal development one.

If you are thinking about growth strategy more broadly, the same logic applies at the organisational level. The frameworks that hold up under pressure, whether from BCG’s commercial transformation work or from hard-won agency experience, tend to share one feature: they are built on honest assessment of where the organisation is strong and where it is not. Growth that is built on a flattering self-image tends not to survive contact with the market.

The broader thinking on go-to-market and growth strategy at The Marketing Juice starts from the same premise: commercial decisions made without honest capability assessment tend to create the problems they were meant to solve.

The Difference Between Delegation and Gap Coverage

There is a version of delegation that is about workload management. You have too much to do, so you hand things down. That is useful and necessary, but it is not what I am talking about here.

Gap coverage is different. It is the deliberate act of hiring or promoting people who are genuinely better than you in specific areas, giving them real authority in those areas, and building your leadership model around that rather than despite it. This is harder than it sounds because it requires you to be honest with yourself and with the organisation about where your authority comes from and where it does not.

When I grew a team from around 20 people to over 100, the hires that made the most difference were not the ones who filled capacity. They were the ones who filled capability gaps I had been honest enough to name. A strong finance director who could hold me accountable on margins. A creative director whose instincts I trusted more than my own in certain contexts. A head of data who could translate performance signals I was reading at surface level into something more precise.

Each of those hires required me to say, explicitly or implicitly: I am not the best person in this room for this. That is not a comfortable admission when you are the one responsible for the P&L. But it is the right one.

What Incomplete Leadership Looks Like in Practice

It does not look like visible uncertainty or public hand-wringing. The leaders I have seen do this well are not the ones who perform humility. They are the ones who have a clear-eyed view of where they add value and build the rest of the structure accordingly.

In practice, this shows up in a few specific ways.

They ask better questions than they give answers, particularly in domains where they know their knowledge is partial. Not performatively, not as a facilitation technique, but because they genuinely want the input of someone who knows more than they do in that area.

They create conditions where people around them can tell them they are wrong. This is harder to build than most people admit. It requires a consistent track record of not punishing the person who brings the uncomfortable view. In agencies especially, where the leader’s taste and judgement often define the culture, this takes real discipline.

They do not confuse confidence in their overall direction with certainty about every decision within it. I have seen senior marketers hold a clear strategic view of where a business needs to go while being genuinely uncertain about specific execution choices. That combination, directional confidence with tactical humility, is rarer than it should be.

And they are honest about what they are optimising for. When you understand your own gaps, you also understand which decisions you are making from strength and which ones you are making from instinct in an area where your instinct has not been tested enough. That distinction changes how you present decisions to boards, clients, and teams.

The Ego Problem Nobody Talks About Directly

Most senior leaders will tell you they are self-aware. Very few of them are as self-aware as they think they are. This is not a character flaw. It is a structural problem. The higher you rise, the fewer people around you will tell you something uncomfortable without first calculating the personal cost of doing so.

I have been in rooms with very senior marketing leaders, people managing hundreds of millions in spend across large portfolios, who were operating on a self-image that had not been seriously challenged in years. Not because they were bad at their jobs. Because the feedback mechanisms around them had quietly broken down. The team had learned what to say. The agency had learned what to present. The data had been framed to support the direction already chosen.

This is not a personal failing. It is a system failure. And it is one that incomplete leaders, the ones who have stayed honest about their gaps, are better equipped to prevent. Because they have built their structures with the explicit intention of being challenged, rather than confirmed.

Forrester’s work on intelligent growth models points to a similar structural issue at the organisational level: growth strategies that are built around a leader’s existing worldview rather than an honest assessment of market conditions tend to underperform the ones built on genuine external input. The principle holds at the individual level too.

How This Plays Out in Go-To-Market Decisions

Go-to-market decisions are where leadership gaps become most commercially visible. A leader who overestimates their understanding of a customer segment will build a positioning that feels right internally and lands flat externally. A leader who overestimates their grasp of channel economics will allocate budget in ways that look coherent on a plan and underperform in market.

I have seen this pattern across multiple industries. The leader with a strong instinct for brand but a limited grasp of performance mechanics who builds a go-to-market plan that is beautiful and does not convert. The leader with a strong grasp of acquisition economics who builds a plan that drives volume but erodes the brand equity that made the acquisition economics work in the first place.

Neither of these is a failure of intelligence. Both are failures of self-knowledge applied to team design. If the brand-led leader had covered their performance gap with a strong hire and given that person genuine authority, the plan would have been better. If the performance-led leader had done the same for brand, same result.

The challenge with go-to-market specifically is that the gaps tend to show up slowly and then all at once. You can run a flawed strategy for longer than you should be able to because the feedback loops are long. By the time the market tells you something is wrong, the leader has often doubled down rather than reassessed. Understanding market penetration dynamics, as frameworks like Semrush’s market penetration analysis illustrate, requires an honest read of where your current capability actually sits relative to where you need it to be.

This is also where the healthcare and regulated sector examples are instructive. Forrester’s analysis of go-to-market struggles in healthcare identifies a consistent pattern: organisations entering complex markets with a self-image that does not match their actual capability in that context. The product may be strong. The leader may be experienced. But the specific combination of market complexity and internal capability gap creates the failure, not either factor alone.

The growth strategy thinking I find most useful, and that I return to across different client contexts, starts with capability honesty before it gets to market opportunity. You can find the opportunity and still fail to capture it if you are not honest about what your team can actually execute.

The Practical Work of Knowing Your Gaps

This is not about personality assessments or 360-degree feedback processes, though both have their place. It is about building habits of honest self-assessment into the way you lead.

One habit that has served me well: after significant decisions, particularly ones that did not go as planned, asking not just what went wrong but where my read of the situation was off. Not in a self-flagellating way. In a diagnostic one. Was this a gap in my knowledge of the market? A gap in my read of the team’s capability? A gap in my understanding of the client’s actual priorities versus their stated ones? Each of those has a different implication for what to do differently next time.

Another habit: being explicit with your senior team about where you are relying on their judgement rather than your own. Not as a performance of humility. As a practical signal that tells them their input is genuinely shaping the decision, not just being consulted for form. The difference in the quality of input you get when people believe they are actually being heard is significant.

A third: paying attention to where you feel defensive. Defensiveness in a leader is almost always a signal that a gap has been touched. Not always a gap that matters, but worth examining. The areas where you push back hardest on challenge are often the areas where your self-assessment is least reliable.

None of this is complicated. Most of it is just uncomfortable. Which is why it does not happen as often as it should.

The growth strategy content on The Marketing Juice covers these dynamics across a range of contexts, from go-to-market planning to commercial transformation. The leadership dimension is often the one that gets least attention in those conversations, and it is frequently the one that determines whether the strategy works.

Incomplete Is Not the Same as Underprepared

There is a version of this argument that gets misread as an excuse for not doing the work. It is not. Knowing your gaps does not mean accepting them as permanent. It means being honest about where you are right now while you build toward where you need to be.

The leaders I have seen use this well are voracious learners in the specific areas where they know they are weak. They are not performing humility about their gaps. They are actively closing them, while simultaneously building teams that cover the gap in the interim. Those are not contradictory positions. They are the same position held at two different time horizons.

What they do not do is pretend the gap is not there while they work on it. That pretence is where the commercial damage happens. When a leader signals false confidence in an area of genuine weakness, the team stops compensating for the gap because they do not know it exists. The client stops flagging concerns because the leader has communicated that concerns in that area will not land well. The organisation optimises around a fiction.

BCG’s work on commercial transformation consistently identifies leadership honesty about capability as a precondition for effective change. Not as a nice-to-have cultural element. As a structural requirement. Organisations that cannot name their own gaps cannot close them. Leaders who cannot name their own gaps cannot build teams that compensate for them.

The most commercially effective leaders I have worked with or alongside over 20 years share this quality more consistently than any other. Not intelligence, not charisma, not strategic vision, though all of those matter. Honest self-knowledge, applied to team design and decision-making in a way that makes the whole more capable than any individual within it.

That is what incomplete leadership actually looks like when it works. Not a gap in capability. A gap in pretence.
