The statement “Leaders should lead, and managers should manage” implies a sharp division between the two organisational functions. It is a common belief, often echoed in boardrooms, management training, and leadership theory. They suggest that these roles are distinct and require different sets of skills, mindsets, and some even go as far as to suggest that even personalities differ.
However, is this separation still valuable for today’s dynamic business environment? Or does it oversimplify the realities of modern leadership?
In this article, I draw on key thinkers such as Kotter (1990) and Harrison (2018) to explore the theoretical roots of the leadership-management distinction. I will also reflect on lived experience and professional practice to examine where these roles overlap, how they are often misunderstood, and why blending them may be more beneficial than keeping them apart.
What the Theory States: Leadership vs Management
Kotter’s Distinction
John Kotter (1990) provides a clear differentiation between leadership and management. According to his framework, management includes planning and budgeting, organising and staffing, and controlling and problem-solving. Leadership, in contrast, focuses on establishing direction, aligning people, motivating employees and inspiring teams.
This distinction emphasises that managers set their sights on maintaining order and consistency, while leaders drive change and inspire people around a vision (Kotter, 1990).
Harrison’s Perspective:
Christian Harrison (2018) further distinguishes between management and leadership by emphasising that management aims to meet organisational goals efficiently and effectively, while leadership is more complex, dealing with variables such as influence, motivation, and change. Leadership is about meeting objectives and inspiring and guiding people to achieve them.
Stogdill’s Perspective:
Another Author who contributed to the distinction between leadership and management is Ralph Stogdill. His research and definitions have evolved, reflecting the ever-changing nature of leadership.
Early Definitions (1948) of leadership were defined as “the behaviour of an individual while he is directing group activities.” This definition emphasises the behavioural aspect of leadership, focusing on leaders’ actions in guiding and directing followers.
Later refinement (1977) refined his definition of leadership by describing it as the influential increment over and above mechanical compliance with the organisation’s routine directives. This highlights the additional influence that leaders exert beyond mere managerial directives.
His work laid the foundation for behavioural theories of leadership, which focus on the actions and behaviours that make leaders effective.
Real-World Lessons: When Leading and Managing Fall Apart
I conducted informal research to explore the distinction in action across a range of organisational sizes. Micro-enterprises (fewer than 10 employees), SMEs (10 to 200 employees), and large organisations (200+ employees). Within each group, I selected companies from the lower, middle, and upper ends of the employee range, for instance, SMEs with 15, 95, and 179 employees. This aimed to provide a representative snapshot of each group.
Reviewing the data, it became evident that many individuals in leadership roles were performing managerial functions, and vice versa. This ‘overlap’ often blurred the distinction between the two domains. There were significant examples where leadership and management were misaligned.
In one case, I observed a textbook manager in Kotter’s sense: she excelled at planning, organising, and controlling. However, her communication style was overly directive, earning her the nickname “Drill Sergeant.” Despite her competence in systems and execution, she lacked emotional intelligence, soft skills and team awareness. The result was a demotivated and disengaged workforce. Eventually, she was reassigned to a role where her organisational strengths could be applied behind the scenes.
In contrast, another team leader demonstrated every quality Kotter associates with leadership: he could align, inspire, and engage with ease. Unfortunately, he lacked basic managerial capability. To the point that colleagues jokingly called him “Pleasant Smell,” suggesting he could not even organise a pleasant smell at a perfume factory. Despite his charisma, his inability to structure operations undercut his effectiveness.
Perhaps the most revealing case involved a co-owner and acting COO of a small to medium-sized enterprise (SME) with nearly 200 staff. He was neither managing or leading; he was occupying a title. His behaviour aligned with Ladkin’s (2019) concept of headship, supported by Kort’s (2008) work. Headship refers to the positional authority someone holds within an organisation, independent of their ability to lead or manage. Leadership requires influence and engagement; management demands planning and control. This individual embodied neither, and the organisation suffered as a result.
In a follow-up conversation, the remaining partner said plainly: “I could not keep doing all the work myself.” He bought him out and appointed both a general manager and a technical manager, reporting that much better results were being achieved.
When Leadership and Management Work Together
I have also seen and experienced the powerful results that come from blending leadership and management in practice.
One of the clearest examples was a former CEO with whom I worked closely over several years. He successfully implemented and executed both roles. When needed – a leader, where he set strategic direction, inspired teams, and fostered innovation, which aligns closely with transformational leadership theory (Bass & Avolio, 1994). He also incorporated servant leadership traits (Greenleaf, 1977), engaging employees through empathy, purpose, and trust.
He did not stop there, and when needed or in response to operational demands, he would shift into a managerial mode. Ensuring that systems were efficient, short-term goals and deliverables were met. While still ensuring that long-term sustainability remained on track. This adaptability made him remarkably effective across multiple dimensions of the organisation.
At the time, I was the general manager working under his leadership. He introduced me to the practical value of holding both capabilities and helped me develop my ability to lead and manage simultaneously.
A simple example was during the launch of a new software package. I led by envisioning its market impact and defining a strategic rollout. Worked with teams to ensure alignment and buy-in, while also having to manage the delivery, allocate resources, react to daily functional issues and monitor timelines. I was able to motivate staff through shared purpose and vision, while also solving problems and overseeing operations.
This experience led me to begin exploring structured ways to blend leadership and management more deliberately, an idea I have continued to develop and apply over time.
Critical Reflection: Blending the Roles in a Resource-Stretched Reality
The phrase “Leaders should lead, and managers should manage” risks, oversimplifies the complex and often overlapping demands placed on modern professionals. While theory (Kotter, 1990) provides helpful distinctions, today’s organisations increasingly rely on individuals who can fluidly move between both roles.
Effective performance now requires engaging and motivating teams while simultaneously ensuring structure, systems, and stability. This blend is especially relevant in today’s resource-constrained environment, where people, time, and capital are all in short supply.
Motivating employees involves understanding human needs and aligning them with business objectives. This is best described in Self-Determination Theory (Deci & Ryan, 1985) and Transformational Leadership models (Bass & Avolio, 1994). At the same time, managing requires planning, organising, and control to ensure that execution keeps pace with intention.
Holding a title is not enough. As Ladkin (2019) and Kort (2008) suggest, headship is where the mere appointment into a position offers no guarantee of influence or impact.
To drive performance and stability, leaders need to also manage. Managers must also be equipped with the ‘know-how’ to lead effectively when the need arises.
Conclusion: Towards the Modo Leader
The distinction between leadership and management remains valuable for understanding organisational dynamics, but in practice, these roles are far more blurred and intertwined than traditional theory suggests.
Yes, leaders should lead by inspiring and guiding their teams. Moreover, yes, managers should manage through structure, efficiency, and oversight. Nevertheless, the most effective professionals in today’s organisations blend both capabilities. They are leader-managers who are capable of vision and action, as well as inspiration and control.
So, where do I stand on the question: Should leaders only lead, and managers only manage?
My answer is yes and no.
Yes, because leadership and management are distinct capabilities.
No, because separating them limits effectiveness in a fast-moving world.
The professionals I admire most, the research I have done and the path I have followed myself combine both disciplines. They switch fluently between inspiration and execution, vision and delivery. That balance is where real influence happens.
I call this person a Modo Leader.
The term is derived from the Latin words modus (meaning “measure” or “method”) and modo (meaning “now” or “recently”). A Modo Leader is someone who manages and leads in the moment, with relevance, intentionality, and adaptability. It is not about role or title; it’s about capability.
It is a mindset for the future of leadership, and it starts here.
It is essential to note that the ‘Modo Leader’ is more than just a name for blending the roles of manager and leader. It is a capability-based mindset, not a personality type. It challenges the old binaries of ‘leader’ and ‘manager’ by offering a practical, learnable model. Modo Leaders are not born that way; they are developed through deliberate practice and continuous learning. These are not abstract traits but skills that can be taught, measured, and applied. While this article introduces the term, there is much more to it. Modo Leaders cultivate six core capabilities that guide behaviour, culture, and decision-making in complex environments, a topic I will explore more deeply in future work.
