In the world of management, certain quotes become accepted, often repeated without question. One such quote is, “You can only manage what you measure.” At first glance, this phrase seems to encapsulate a straightforward truth about the importance of metrics in management. Afterall, how can you confirm whether something is improving performance-wise if you don’t measure it? However, like many sayings, it oversimplifies a more complex reality. Understanding why this phrase is misleading can help in determining a better approach. This in turn will lead to better management practices which are more suitable for real-life management scenarios.

“You Can Only Manage What You Measure” is a Misquote

The quote “you can only manage what you measure” is often attributed to Peter Drucker. Drucker was a management guru who was known as “the man who invented management”. Although, there is no clear evidence that he actually said or wrote these exact words. Nevertheless, the phrase has gained traction because it echoes the need for data and metrics to inform decisions. The appeal of the quote lies the simplicity of the action is suggests – measure more to manage better.


This saying has several limitations that make it a poor guiding principle for managers:

  • Overreliance on Quantitative Metrics
  • The Risk of Mismanagement
  • The Importance of Intuition and Experience

Overreliance on Quantitative Metrics

One of the primary issues with this misquote is its overreliance on quantitative metrics. While data is crucial for understanding certain aspects of a business, it does not capture everything. Qualitative factors such as employee morale, customer satisfaction, and corporate culture are also important for managers to consider. However, unlike quantitative data, it is often harder to measure. Relying solely on measurable data can lead to neglecting these elements. This will result in a narrow view of what needs managing.

The Risk of Mismanagement

Focusing exclusively on what can be measured can also lead to mismanagement. Metrics can be manipulated, misunderstood, or taken out of context. For example, a company might measure productivity by the number of hours employees work. However, this doesn’t reflect the quality or impact of their work. Misinterpreting these metrics can lead to misguided strategies and poor decision-making.

The Importance of Intuition and Experience

Good management often relies on intuition and experience, which are not easily quantified. Experienced managers use their insights and instincts to make decisions, especially in complex or rapidly changing situations where data might be unavailable. Ignoring these non-measurable factors can hinder effective management.

A More Balanced Approach

To move beyond the limitations of the misquote, it’s essential to adopt a more balanced approach to management:

  • Combine Quantitative and Qualitative Data
  • Focus on Key Performance Indicators (KPIs)
  • Foster a Culture of Continuous Improvement
  • Use Data to Inform, Not Dictate

Combine Quantitative and Qualitative Data

Use both quantitative and qualitative data for a more effective management approach. While metrics provide valuable insights, qualitative information offers context and depth. Combining these types of data can lead to more comprehensive and informed decision-making.

Focus on Key Performance Indicators (KPIs)

Not everything that can be measured is important, and not everything that is important can be measured. Managers should ensure they identify KPIs that truly reflect the success of the organisation. The KPIs should align with strategic goals while also providing actionable insights.

Encourage Continuous Improvement

Managers should prioritise a culture of continuous improvement over strictly following metrics. This includes regularly reviewing and adjusting strategies and metrics to ensure they always align with business success. Managers should also continue to learn and develop their skills to become more adaptable in their management practices.

Use Data to Inform, Not Dictate

Data should guide and inform decisions, not dictate them. Managers should use data as a tool by balancing it with their own experience, intuition, and understanding of the broader context.

Achieving Organisational Success With Effective Management Practices

The saying “You can only manage what you measure” highlights the importance of metrics for efficient management. However, it falls short by oversimplifying the complexities involved. Effective management requires both quantitative and qualitative data, recognises the limits of metrics, and leverages the insights and experience of managers. A more balanced approach to management will lead to the organisation achieving sustained success and growth.
