Why even the best leaders derail

Even the best leaders can derail when they lack self-awareness and don’t minimize their performance risks and potential derailment factors as they progress into more senior roles. There are a wide range of derailers beyond failing to meet their business objectives that leaders need to be aware of. Here’s what our own experience, together with decades of research, suggest are the biggest problem areas:

Overuse or poor use of strengths

It may come as a surprise to many that the majority of leaders don’t fail because of obvious competency weaknesses or skill shortfalls. They fail because of overdrive risks associated with using their strengths too much or in the wrong way. Yet research shows that most leaders remain totally unaware of their overdrive risks and how these undermine performance.

A common example of this often arises in leaders having strong levels of confidence, or belief in their abilities and judgement. When used well, this strength helps them make clear decisions and manage effectively, particularly during periods of rapid change and high uncertainty. However, there is a fine line between confidence and arrogance. Arrogant leaders believe they are right and others are wrong; they stop listening and involving others so strong is their belief in their own abilities and judgement. When taken to the extreme, overconfident leaders become increasingly obsessive about driving their own agenda and try to force through their decisions and ideas, undermining trust, respect and morale of those around them.

Lack of agility

Many leaders derail because they are unable to develop or adapt, they get left behind as the organization and environment evolves and changes. With the increasing magnitude and pace of environmental changes, including digital technologies and AI reinventing the way work is done, this will become an increasingly common source of derailment. Leaders who aren’t curious and open to change and don’t experiment with new technologies and ways of working are those most at risk. They can’t afford to have a “fixed mindset” and resist learning new skills otherwise they will become casualties of the digital age we have entered.

Other leaders struggle to adapt to a new boss, executive or other key stakeholder(s) with a different style and approach. They dig in and fail to develop a good working relationship with their boss and/or key stakeholders because they lack the interpersonal flexibility and range of communication and influencing skills required at more senior organizational levels.

Problematic interpersonal skills

Research shows that this is one of the most common sources of derailment. Problems often arise because as leaders move into more senior positions, they can no longer reply on their specialised knowledge and task-based management approach that worked for them earlier in their career. The need to build and maintain a complex network of working relationships and engage and influence people with a diverse range of styles, perspectives and backgrounds. They also need to navigate what is often a complex political environment where engaging people to support their ideas and opinions is often just as important as the solution itself. Problems with interpersonal skills are often loosely labelled “low emotional intelligence” by HR and top management and include common problems like being overly critical, bullying behaviours, the inability to control one’s temper and cold, insensitive behaviour.

Inability to build a strong team

Leaders who are unable to hire the best talent and build strong teams are unlikely to succeed, particularly when they move into more senior positions. Common problems include:

  • Failing to hire strong, diverse talent

The best leaders learn to challenge subjective and unconscious bias during the hiring process. They put in place hiring processes that pinpoint the best talent using objective interview and assessment methods, including psychometric testing. They also surround themselves with complementary and diverse people rather than hiring clones who are unlikely to challenge them.

  • Inability to engage and lead a team

Leaders who succeed inspire others with a clear, meaningful picture of future success. They usually have engaging personalities and build trust and respect through involving, empowering and supporting others, rather than using directive and coercive methods to achieve their goals.

  • Poor management of underperformance

Leaders need to build skill and confidence to deal with poor performers in order to succeed otherwise results will suffer and team morale will deteriorate. They need to have candid conversations with people about areas of underperformance and provide support, direction and coaching to help them improve. However, they also need to act decisively when performance problems can’t be resolved, including firing people with the support of HR when necessary.

Poor personal energy management 

The demands and pressures on leaders have never been greater. The pace and complexity of change is growing exponentially, and this puts enormous mental, emotional and physical pressure on leaders. This is one reason why the wellbeing and mindfulness movements have grown so rapidly in recent years. Leaders who don’t look after their wellbeing and capacity to manage their demands are more susceptible to burning out. A lot of research during the past decade has shown that leaders who don’t manage their energy and time productively, including failing to delegate sufficiently, end up exhausted, are more prone to emotional outbursts and make inferior decisions. Regular lack of sleep also raises cortisol levels, weakens the immune system and increases the risks of illness.
