Hurdle Rate

Introduction: Hurdle Rate (in Process Improvement Investments)

The Hurdle Rate is the minimum acceptable rate of return that an organisation requires before approving an investment or project. In the context of process improvement, it serves as a financial benchmark for deciding whether Lean, Six Sigma, or other improvement initiatives justify the resources and risks involved.

Background

The concept originates in corporate finance, where managers use the hurdle rate to screen potential investments. It is closely linked to the cost of capital and risk assessment. In process improvement, applying a hurdle rate ensures that improvement projects are not only operationally effective but also financially sound. By comparing expected benefits (such as cost savings, efficiency gains, or revenue growth) to the hurdle rate, organisations can make disciplined choices about which initiatives to pursue.

Key Elements / Features

• Definition: The minimum return required for an investment to be considered viable.
• Financial basis: Typically tied to the weighted average cost of capital (WACC) or adjusted for project-specific risk.
• Decision-making tool: Projects with an expected return above the hurdle rate are accepted; those below are rejected.
• Risk adjustment: Higher-risk projects may require a higher hurdle rate to justify investment.
• Application in Lean Six Sigma: Ensures that improvement projects deliver measurable financial value, not just process efficiency.

Applications / Examples

• Manufacturing: Approving a Lean automation project only if projected savings exceed the hurdle rate.
• Healthcare: Evaluating whether a new patient management system reduces costs enough to meet financial return thresholds.
• Service industries: Comparing the benefits of customer service training to the hurdle rate before committing resources.
• Process excellence programmes: Screening multiple Six Sigma projects to prioritise those with the strongest financial impact.

Relevance / Impact

Using a hurdle rate in process improvement investments ensures that organisations:

• Align operational changes with financial strategy.
• Avoid committing resources to projects with limited or uncertain returns.
• Balance efficiency improvements with financial discipline.
• Increase accountability in selecting and prioritising initiatives.
