Meaning and Importance

Controlling

The management process of systematically monitoring organizational activities, comparing actual performance against established standards, and taking corrective action to rectify any significant deviations.

Controlling is the crucial final link in the functional chain of management. It is the only reliable way managers know whether organizational goals—established during the planning phase—are actually being met, and if not, why they are failing. It provides an essential feedback loop that informs future planning cycles. Without control, an organization is flying blind.

The Control Process

The control process is a continuous, three-step cycle that applies to any activity, from a massive infrastructure project to an individual employee's daily output.

Three-Step Control Process

  1. Measuring Actual Performance: Acquiring reliable data on what is actually happening. Methods include personal observation (management by walking around), statistical reports (dashboards, charts), oral reports (meetings, one-on-ones), and formal written reports.
  2. Comparing Actual Performance Against Standards: Determining the degree of variation between the actual performance measured in Step 1 and the standard (the goal) established during the planning phase.
  3. Taking Managerial Action: If the deviation is significant, the manager must act. This can involve correcting actual performance (e.g., repairing a machine, retraining an employee) or, if the original goal was unrealistic, revising the standard itself.
Performance Measurement and Control Cycle

Compare reliable actual performance with an authorized standard, investigate significant differences, and verify corrective action.

A process-control chart's statistical control limits describe process behavior; they are not automatically specification, tolerance, safety, or contract acceptance limits. Change a standard only through an authorized review supported by changed assumptions or a valid basis.

Range of Variation

Set decision thresholds that fit the measure, risk, and governing specification. Statistical control limits describe expected process variation; they are not the same as engineering specifications, contract acceptance limits, or safety limits. A process can be stable while failing a specification, or unstable while currently producing conforming results. Investigate meaningful signals and act through authorized procedures.

Types of Control

Controls can be implemented at different stages of an operational process. Effective engineering managers utilize a combination of all three.

Timing of Control Mechanisms

  • Feedforward Control (Input Stage): This is proactive control that anticipates and prevents problems before they occur. It focuses on the quality of inputs (human, material, financial) before work begins.
    Example: Rigorously testing raw concrete batches before pouring a foundation.
  • Concurrent Control (Process Stage): This is active, real-time control that corrects problems as they happen during the transformation process. It ensures the process complies with directives.
    Example: A site supervisor immediately stopping a crane operator who is lifting a load incorrectly.
  • Feedback Control (Output Stage): This is reactive control that corrects problems after they occur. It focuses on the final outputs or results. While the damage is already done, it provides vital data for future improvement.
    Example: Analyzing a failed bridge component after a collapse to update future design codes.
Control Timing Follows the Work

Choose a control point based on when useful evidence becomes available.

Feedforward checks inputs before transformation; concurrent checks observe work while it happens; feedback checks outputs and results. Complex engineering work can use all three at once.
Before work: verify materials, competence, and readiness
During work: inspect process conditions and respond
After work: evaluate outputs and feed lessons forward

Financial Controls

Every organization relies on financial resources, making financial controls universal and critical for survival.

Budgets

Budgets are formal, numerical plans for allocating resources to specific activities over a given timeframe. They act as both a planning tool and a strict control mechanism.

  • Operating Budget: Details planned revenues, expenses, and expected profit for a specific period.
  • Cash Budget: Forecasts cash inflows and outflows to ensure the company has enough liquid cash on hand to meet obligations (e.g., payroll).
  • Capital Expenditure Budget: Details planned investments in major, long-term assets like property, heavy machinery, and new facilities.

Financial Ratios

Financial ratios are calculated by comparing selected items on the balance sheet and income statement to assess organizational health.

  • Liquidity Ratios (e.g., Current Ratio): Calculated as Current Assets / Current Liabilities. It tests the organization's ability to meet its short-term debt obligations.
  • Leverage Ratios (e.g., Debt-to-Assets Ratio): Calculated as Total Debt / Total Assets. It measures the percentage of total assets financed by creditors versus owners, indicating financial risk.
  • Activity Ratios (e.g., Inventory Turnover): Calculated as Cost of Goods Sold / Average Inventory. It measures how efficiently the organization is managing its physical inventory.
  • Profitability Ratios (e.g., Return on Investment - ROI): Calculated as Net Profit / Total Investment. It measures the efficiency of assets in generating profit for the organization.

Audits

Planned, evidence-based examinations of selected financial or operational information against defined criteria. An audit provides a level of assurance within its scope; it does not guarantee that every error or fraud has been detected. Applicable duties vary by entity, engagement, and jurisdiction.

  • External Audits: Conducted by an independent practitioner under the applicable engagement and standards. The report expresses an opinion or conclusion within its defined scope; it is not a guarantee of absolute accuracy.
  • Internal Audits: Conducted by the company's own employees to proactively ensure that internal operating procedures, safety protocols, and management directives are actually being followed correctly on the factory floor or construction site.
  • Management Audits: A holistic evaluation of the overall efficiency and effectiveness of the management team itself in utilizing resources to achieve strategic goals.

Non-Financial Controls

Relying solely on financial metrics provides an incomplete picture. Modern management requires balancing financial outcomes with operational drivers.

Benchmarking

A structured comparison of selected products, services, or processes with relevant internal or external reference points. Use comparable measures, understand context, and adapt useful practices rather than assuming another organization's approach transfers unchanged.

Management Information Systems (MIS)

People, procedures, and technology that collect, process, and communicate information for decisions. Information can be delayed, incomplete, or uncertain, so managers should check definitions, data quality, and update frequency before acting.

The Balanced Scorecard

A strategic performance management tool that evaluates an organization from four distinct perspectives, ensuring that short-term financial gains are not achieved at the expense of long-term viability.

  • Financial Perspective: How do we look to shareholders? (e.g., revenue growth, cost reduction).
  • Customer Perspective: How do customers see us? (e.g., customer satisfaction scores, market share).
  • Internal Business Processes Perspective: At what processes must we excel? (e.g., manufacturing cycle time, quality defect rates).
  • Learning and Growth Perspective: How can we continue to improve and create value? (e.g., employee training hours, retention rates of key personnel).
Balanced Scorecard Perspectives

A balanced scorecard connects outcome measures with customers, processes, and organizational capability.

Select measures that support the strategy and clarify their cause-and-effect assumptions. The four perspectives are complementary prompts, not a mandatory universal set of metrics.
Financial: resource and outcome measures
Customer: user and stakeholder outcomes
Internal process: quality, reliability, and delivery
Learning and growth: capability and improvement
Financial and Operational Evidence

Use financial and nonfinancial indicators together to understand performance and its drivers.

A budget variance or ratio can reveal a result; operational measures can help explain its causes. Neither category alone proves causation, so confirm with context and reliable source data.
Financial measures
  • Budget and cash position
  • Selected financial ratios
  • Cost and return trends
Operational measures
  • Quality and rework
  • Schedule and throughput
  • Safety, service, and capability
Key Takeaways
  • Controlling acts as the crucial final check in the management cycle, ensuring that actual activities align with planned goals and standards, providing a feedback loop for future planning.
  • The continuous control process involves three distinct steps: Measure Actual Performance, Compare Against Standards, and Take Corrective Action (if deviations exceed the acceptable range of variation).
  • Organizations utilize different control types based on their timing relative to the process: Feedforward (proactive/input), Concurrent (real-time/process), and Feedback (reactive/output).
  • A holistic control system requires both rigorous Financial Controls (e.g., Budgets, Ratios, External/Internal Audits) and Non-Financial Controls (e.g., Benchmarking, MIS, and the Balanced Scorecard) to ensure long-term organizational health.
