A performance indicator or key performance indicator (KPI) is a type of performance measurement. [1] KPIs evaluate the success of an organization or of a particular activity (such as projects, programs, products and other initiatives) in which it engages. [2] KPIs provide a focus for strategic and operational improvement, create an analytical basis for decision making and help focus attention on what matters most. [3]

Contents

Often success is simply the repeated, periodic achievement of some levels of operational goal (e.g. zero defects, 10/10 customer satisfaction), and sometimes success is defined in terms of making progress toward strategic goals. [4] Accordingly, choosing the right KPIs relies upon a good understanding of what is important to the organization. [5] What is deemed important often depends on the department measuring the performance – e.g. the KPIs useful to finance will differ from the KPIs assigned to sales.

Since there is a need to understand well what is important, various techniques to assess the present state of the business, and its key activities, are associated with the selection of performance indicators. These assessments often lead to the identification of potential improvements, so performance indicators are routinely associated with 'performance improvement' initiatives. A very common way to choose KPIs is to apply a management framework such as the balanced scorecard.

The importance of such performance indicators is evident in the typical decision-making process (e.g. in management of organisations). When a decision-maker considers several options, they must be equipped to properly analyse the status quo to predict the consequences of future actions. Should they make their analysis on the basis of faulty or incomplete information, the predictions will not be reliable and consequently the decision made might yield an unexpected result. Therefore, the proper usage of performance indicators is vital to avoid such mistakes and minimise the risk. [6] [7]

KPIs are used not only for business organizations but also for technical aspects such as machine performance. For example, a machine used for production in a factory would output various signals indicating how the current machine status is (e.g., machine sensor signals). Some signals or signals as a result of processing the existing signals may represent the high-level machine performance. These representative signals can be KPI for the machine.

Categorisation of performance indicators

The effective use of performance indicators requires a clear understanding of their different types and purposes. Indicators can be categorised along several key dimensions to ensure a balanced and comprehensive measurement system that supports strategic objectives. A well-designed set of indicators will draw from multiple categories to avoid unintended consequences and provide a holistic view of organisational performance. [5]

A primary method of categorisation is based on the dimension of performance being measured. The Balanced Scorecard framework, for instance, groups indicators into four perspectives: financial (e.g., profitability), customer (e.g., satisfaction), internal business processes (e.g., efficiency), and learning and growth (e.g., innovation). [8] This approach prevents over-reliance on financial metrics alone.

Indicators are also commonly distinguished by their time orientation and function. In this typology:

Another critical distinction is based on the nature of the data. Quantitative indicators provide objective, numerical measurement (e.g., unit output, error rates), while qualitative indicators capture subjective, often perceptual data (e.g., stakeholder satisfaction, brand reputation) typically gathered through surveys and interviews.

Furthermore, indicators can be designed for different levels of the organisation. Strategic indicators monitor progress toward top-level goals, operational indicators track departmental or process efficiency, and individual indicators align personal objectives with organisational priorities.

Selecting the right mix of categories is a strategic exercise. An overemphasis on lagging quantitative indicators can lead to short-termism and "gaming" of metrics, while focusing solely on leading or qualitative indicators may lack a connection to ultimate outcomes. [9] A balanced portfolio of indicators across these categories is therefore essential for effective performance management.

Points of measurement

The first step in performance measurement is determining what to measure.

Performance indictors may be applied at various stages within a programme, service, or organisational process. These points capture distinct dimensions of performance, ranging from the earliest stages of resource allocation to final outcomes achieved. It is common to distinguish between: [10]

Mapping indicators across this continuum helps ensure measurement provides a clear picture of performance. The points of measurement may also relate to the relationship between inputs and outputs (productivity), and outputs and outcome (effectiveness). [11] Control (the extent to which employees can influence a result) and mechanism (the causal link between employees’ effort and a performance dimension) further shape measurement decisions.

Selecting the appropriate point of measurement is not simply a technical choice but also a strategic one. For example, focusing narrowly on inputs or outputs can incentivise ‘box-ticking’ behaviours and obscure whether real value is being created. [12] Conversely, outcome and impact indicators may harder to attribute to organisational effort, especially in complex public sector environments. [13]

A balanced approach can involve linking indicators across multiple points of measurement, to trace the relationships between resources, activities and ultimate value. [14] However, this requires careful design to avoid measurement burdens and to ensure alignment with an organisation’s overall strategic objectives.

Quality assurance across the points of measurement helps ensure indicators not only track activity levels but also produce robust, consistent and credible performance data. [15]

Identifying indicators

Once appropriate points of measurement have been determined, the next task is to identify specific indicators that meaningfully capture performance at that stage. An indicator is a measurable variable used to show whether progress is being made towards a goal, rather than the goal itself. [16]

Choice of indicators reflects managerial decisions about what counts as successful performance. [17] Indicators may be financial, such as revenue growth, or non-financial, such as customer satisfaction rates. [18] A good indicator should be simple to understand while aligning closely with business or organisational goals. [19]

The process of identifying indicators is often guided by frameworks such as SMART (specific, measurable, achievable, relevant, time-bound). [20] Alternatives like the FABRIC principles emphasise ideal performance information is focused, appropriate, balanced, robust, integrated, and cost-effective. [21]

In the public sector, where outcomes may depend on many different organisations and external influences, careful selection is needed to avoid misleading or overly broad results. [22]

Key stages of identifying a performance indicator include: [23] [24]

Beyond the technical steps, several broader considerations shape indicator usefulness. Indicators must understandable for managers and other stakeholders, including shareholders or the public, to understand but precise enough to capture what matters. Over-simplified indicators may distort or fail to drive performance, while overly complex or too numerous indicators may fail to gain traction. [25]

Attribution is another challenge. In the public sector, multiple organisations may influence outcomes indicators, and may sometimes develop a shared outcomes framework with reporting to show the particular role an individual organisation. [26] Where a clear link exists between employee effort and performance, indicators may be connected to motivation, reward and appraisal systems.

Data quality is another important consideration. [21] Indicators depend on reliable and consistent information. Weak systems can undermine credibility, shaping which indicators are ultimately preferred. [27] Finally, given the risks of gaming, data fabrication, and selective reporting on indictors, [28] organisations should consider verifiability of underlying data when selecting indicators and choose indicators that are not susceptible to manipulation. [29]

Examples

Accounts

These are some of the examples:

Marketing and sales

Many of these customer KPIs are developed and managed with customer relationship management software.

Faster availability of data is a competitive issue for most organizations. For example, businesses that have higher operational/credit risk (involving for example credit cards or wealth management) may want weekly or even daily availability of KPI analysis, facilitated by appropriate IT systems and tools.

Manufacturing

Overall equipment effectiveness (OEE) is a set of broadly accepted nonfinancial metrics that reflect manufacturing success.

Professional services

Most professional services firms (for example, management consultancies, systems integration firms, or digital marketing agencies) use three key performance indicators to track the health of their businesses. They typically use professional services automation (PSA) software to keep track of and manage these metrics.

System operations

Project execution

Supply chain management

Businesses can utilize supply chain KPIs to establish and monitor progress toward a variety of goals, including lean manufacturing objectives, minority business enterprise and diversity spending, environmental "green" initiatives, cost avoidance programs and low-cost country sourcing targets. Suppliers can implement KPIs to gain a competitive advantage. Suppliers have instant access to a user-friendly portal for submitting standardized cost savings templates. Suppliers and their customers exchange vital supply chain performance data while gaining visibility to the exact status of cost improvement projects and cost savings documentation.

Any business, regardless of size, can better manage supplier performance and overall supply chain performance, [30] with the help of KPIs' robust capabilities, which include:

Main KPIs for supply chain management will detail the following processes:

In a warehouse, the manager will use KPIs that target best use of the facility, like the receiving and put away KPIs to measure the receiving efficiency and the putaway cost per line. Storage KPIs can also be used to determine the efficiency of the storage space and the carrying cost of the inventory. [31]

Government

Governments around the world have adopted performance indicators as part of broader performance management reforms. These initiatives emerged from general concerns about performance deficits in the public sector, and the belief that systematic measurement could improve accountability and outcomes. [32] While governments have established extensive systems for collecting performance data, research suggests that the value of these indicators depends on whether managers effectively use the information in their decision-making processes.

Factors influencing the use of performance data include individual values, leadership roles, organisational culture, and external pressures. Managers with strong public service motivation are more likely to engage with performance information because they see it as a means of achieving public goals. [33] Leadership roles also matter. Task-specific leaders often use indicators more actively than generalist leaders who face broader political responsibilities. [34] Organisational cultures that emphasise learning, flexibility, and innovation are more likely to foster the use of performance information, whereas rigid or highly centralised environments may discourage it. Citizen participation can also create demand for greater accountability, encouraging managers to apply performance data to justify decisions and demonstrate transparency. [35]

International examples show the diversity of approaches. The provincial government of Ontario, Canada has used performance indicators since the late 1990s to assess higher education institutions, reporting on measures such as graduate satisfaction, employment rates, and student outcomes. [36] In England, Public Health England applies indicators to monitor national health screening programmes [37] , while UK government departments publish key contract-related indicators to improve service transparency. [38] The United States requires federal agencies to set strategic goals and report on progress under the Government Performance and Results Act. [39] The New Zealand Treasury’s Living Standards Framework and associated wellbeing indicators provide a broader set of measures that move beyond economic performance to social and environmental outcomes. [40]

Although performance indicators are now widespread, their effectiveness remains debated. It can be argued that indicators oversimplify complex goals, encourage symbolic compliance, and shift attention to what is easily measurable rather than what is substantively important. On the other hand, when well-designed and used within supportive cultures, indicators can strengthen accountability, guide learning, and improve service delivery. [41]

Human resource management

Performance indicators are widely used in human resource management (HRM) to assess recruitment, retention, performance, and employee well-being. In the public sector, these measures are shaped by distinctive institutional constraints and workforce motivations. Common HRM indicators include employee turnover rates, time to fill vacancies, absenteeism, staff satisfaction, and survey results. [42]

The effectiveness of HRM practices has been examined across public, semi-public, and private organisations. A large meta-analysis using the ability-motivation-opportunity (AMO) framework found that HRM practices positively influence individual performance in all sectors, but with sector-specific variations. [43] Ability-enhancing practices such as training and selective recruitment are consistently associated with higher job satisfaction and performance. [44] Motivation-enhancing practices, such as performance-based pay, show weaker impacts in public organisations, where employees are often driven more by intrinsic and altruistic motivations than extrinsic rewards. [45] Opportunity-enhancing practices, such as participatory decision-making and job autonomy, appear particularly important in encouraging extra-role behaviours like collaboration and knowledge-sharing. [46]

Employee turnover is a critical indicator for HRM. While traditionally seen as negative, research suggests that turnover may have more complex effects. A study of several hundred public school districts in Texas over nine years found that turnover was linearly negative for basic educational outcomes, such as standardised test scores, but showed a non-linear “inverted U-shaped” relationship with more complex outcomes like college readiness. [47] This indicates that low to moderate turnover may introduce new skills and perspectives, benefiting organisational performance, while very high turnover imposes significant costs and reduces effectiveness.

Other HRM indicators reflect absenteeism, which is often monitored as a proxy for workforce wellbeing and organisational health. [48] Staff satisfaction surveys are also commonly used to measure morale, commitment, and engagement, though their interpretation may be shaped by broader organisational culture and leadership practices. [49]

Other performance indicators


Problems

Performance Indicators (PIs) are widely used to measure, manage and provide public accountability across sectors like healthcare, business, education and government. [50] However, they can have challenges and limitations that may affect data accuracy, relevance, and effectiveness if not carefully considered. In practice, overseeing key performance indicators can prove expensive or difficult for organizations. Some indicators such as staff morale may be impossible to quantify. As such, dubious KPIs can be adopted that can be used as a rough guide rather than a precise benchmark. [51]

Key performance indicators can also lead to perverse incentives and unintended consequences as a result of employees working to the specific measurements at the expense of the actual quality or value of their work. [52] [53]

Sometimes, collecting statistics can become a substitute for a better understanding of the problems, so the use of dubious KPIs can result in progress in aims and measured effectiveness becoming different. For example, during the Vietnam War, US soldiers were shown to be effective in kill ratios and high body counts, but this was misleading when used to measure aims as it did not show the lack of progress towards the US goal of increasing South Vietnamese government control of its territory. [51] Another example would be to measure the productivity of a software development team in terms of lines of source code written. This approach can easily add large amounts of dubious code, thereby inflating the line count but adding little value in terms of systemic improvement. A similar problem arises when a footballer kicks a ball uselessly to build up their statistics.

Here are some potential problems, examples and impacts with Performance Indicators:

Overemphasis on Quantitative Metrics [54]

Misalignment with strategic Goals [55]

Gaming the System [56] .

Data Quality and Reliability [57] .

Demotivation, Stress and Burden of Measurement [58]

Equity Blindness [59]

Tunnel Vision [60] .

Strategies to address and mitigate problems with PIs requires a thoughtful, systemic approach. Examples to guide this process are:

Design Indicators for Relevance and Fairness

Transparency and Participation

Monitor for Gaming and Goal Shift

Reduce Monitoring Burden

Equity-Minded Alternatives

Further examples may include in nursing, replacing rigid throughput metrics with indicators that reflect quality of care, and patient experience. In education, balance test scores with indicators of student engagement and learning environment quality. Finally, in public services, include metrics for community impact and equity alongside traditional efficiency indicators.
