Challenger Disaster: Space Shuttle Supply Chain Issues.

Wonder if there are any similarities between the Space Shuttle Disaster and things that have happened with Boeing? The Space Shuttle Challenger disaster of 1986 was caused by a failure in the O-ring seals on the solid rocket boosters. These seals, which were designed to prevent hot gases from escaping the rockets during flight, were found to be susceptible to failure at low temperatures. On the day of the Challenger launch, the temperature was unusually cold, and the O-ring seals failed, causing a catastrophic explosion.

There were several supply chain issues that contributed to the failure of the O-ring seals and the Challenger disaster. One issue was that the supplier of the O-ring seals, Morton Thiokol, had raised concerns about the seals’ ability to perform at low temperatures. However, these concerns were not adequately addressed by NASA, the customer, and the launch proceeded as planned.

Another issue was that there was a lack of communication and collaboration between different parts of the supply chain, including the supplier, the manufacturer, and the customer. For example, Morton Thiokol did not effectively communicate its concerns about the O-ring seals to NASA, and NASA did not adequately consider these concerns when making the decision to proceed with the launch.

The Challenger disaster serves as a reminder of the importance of effective communication and collaboration within the supply chain and the need to address potential risks and issues in a timely and proactive manner. It also highlights the need for robust quality control measures and the importance of ensuring that suppliers meet the necessary standards and requirements for their products.

After the Challenger disaster, the space shuttle program implemented a number of changes to improve safety and prevent similar accidents from occurring in the future. Some of the key changes that were made include:

Improved design and testing of the solid rocket boosters: The O-ring seals on the solid rocket boosters were redesigned to be more resistant to failure at low temperatures. Additionally, more stringent testing and inspection procedures were put in place to ensure the quality and reliability of the seals.
Enhanced safety procedures: The space shuttle program implemented new safety procedures to improve the detection and prevention of potential problems. This included the establishment of a safety panel to review and evaluate safety concerns, as well as the development of new risk assessment tools.
Improved communication and collaboration: The space shuttle program worked to improve communication and collaboration between different parts of the organization, including between management and engineers, and between different contractors and suppliers.
Upgraded hardware and software: The space shuttle program made a number of hardware and software upgrades to improve the performance and safety of the shuttles. This included the installation of new navigation and guidance systems, as well as the development of new computer systems to monitor the performance of the shuttles in real-time.

Overall, these changes helped to significantly improve the safety of the space shuttle program and prevent similar accidents from occurring in the future. However, it’s important to recognize that space travel is an inherently risky endeavor, and it’s always important to continue working to improve safety and reduce the risk of accidents.

“Those in supply chain know the impossible is possible.” ~Dave Waters
As a leader during transformation, you have to be out in front — show that you want to learn, be curious, introduce new ideas, ask questions.” ~Doug McMillon, CEO Walmart.
“It makes no difference to a widow with her savings in a 5 percent passbook account whether she pays 100 percent income tax on her interest income during a period of zero inflation or pays no income tax during years of 5 percent inflation. Either way, she is ‘taxed’ in a manner that leaves her no real income whatsoever. Any money she spends comes right out of capital. She would find outrageous a 100 percent income tax but doesn’t seem to notice that 5 percent inflation is the economic equivalent.” ~Warren Buffett, CEO of Berkshire Hathaway.
“Supply chain is in the crawling stage of using artificial intelligence. In the next 5 years AI will revolutionize supply chain in ways most people haven’t even though of yet.” ~Dave Waters
