Learning from History!! Lessons from Design Failures - The Case of Mishandled Marble Columns

Introduction:

Design changes are like prescribing medication, they come with their own set of side effects. Understanding and addressing these side effects is crucial when implementing design changes. In this article, we will explore the inherent risks associated with design changes and discuss key considerations for successfully managing them. We will also delve into different approaches, such as FMEA (Failure Modes and Effects Analysis) and DRBFM (Design Review Based on Failure Modes), to systematically assess the impact of design changes.

The Risks of Design Changes:

Design changes always carry a certain level of risk. Just because a change seems feasible in the moment, it doesn't mean it should be blindly accepted. It is essential to approach design changes with a critical mindset, questioning their potential consequences and thoroughly evaluating their feasibility. By being aware of the risks involved, designers can make more informed decisions and minimize the chances of failure.

Understanding the Scope and Time-Dependence of Change Effects:

When implementing design changes, it is crucial to consider the broader implications and potential time-dependence of their effects. A change that appears harmless in the short term may have significant consequences in the long run. Therefore, it is essential to systematically analyze and document the potential impact of design changes over time. This allows designers to anticipate and address any unforeseen issues that may arise as a result of the change.

Approaches for Assessing Design Changes:

To effectively evaluate design changes and mitigate risks, various methodologies can be employed. Two widely used approaches are FMEA and DRBFM.

1. Failure Modes and Effects Analysis (FMEA):

FMEA is a systematic technique for identifying potential failure modes and their associated effects. By analyzing each component and its potential failure modes, FMEA helps designers understand the risks associated with design changes. It enables them to prioritize potential failure modes and develop appropriate mitigation strategies. FMEA serves as a proactive tool for risk management, ensuring that potential issues are addressed before they occur.

2. Design Review Based on Failure Modes (DRBFM):

DRBFM is another approach that focuses on the analysis of failure modes and their effects. Unlike FMEA, DRBFM emphasizes the importance of cross-functional collaboration and communication. It encourages designers to involve key stakeholders from different departments to gain a holistic perspective on potential risks and their impact. By fostering collaboration and knowledge sharing, DRBFM enhances the overall effectiveness of risk management during design changes.

The Importance of Addressing Failure Modes:

A common misconception is that failures only occur in the areas where changes were made. However, failures can stem from various interconnected factors, not just the modified components. It is crucial to recognize that failure modes can manifest in unexpected ways, and a comprehensive approach to risk assessment is necessary. By considering the entire system and all its interdependencies, designers can better identify potential failure modes and develop appropriate mitigation strategies.

Actionable Advice:

1. Embrace a holistic approach: When implementing design changes, consider the broader system and all its interconnected components. By taking a holistic perspective, designers can identify potential failure modes that might not be immediately apparent.

2. Foster cross-functional collaboration: Engage stakeholders from different departments to gain diverse insights and perspectives on potential risks. Collaboration enhances risk management efforts and promotes a more comprehensive understanding of the consequences of design changes.

3. Continually monitor and evaluate: Design changes should not be a one-time event. Continuously monitor and evaluate the effects of the changes over time. This allows for timely adjustments and helps mitigate any unforeseen issues that may arise.

Conclusion:

Design changes come with inherent risks, and understanding these risks is essential for successful implementation. By embracing a holistic approach, fostering cross-functional collaboration, and continuously monitoring and evaluating the effects of design changes, designers can minimize the chances of failure and ensure the long-term success of their projects. Learning from historical design failures and incorporating best practices, such as FMEA and DRBFM, can greatly enhance the effectiveness of risk management during design changes. Let's remember that every design change has the potential to impact the overall system, and it is our responsibility to anticipate and address any potential failures that may arise.
