Group projects are meant to combine skills and resources, but they often fail in surprising ways. Common causes include unclear goals, uneven workloads, and technical or management problems. Studying these failures can help future teams avoid the same mistakes and improve collaboration.

The Sydney Opera House suffered extreme scope creep, drastically increasing costs and extending the timeline. The project was originally estimated at AU$3.5 million but ended at AU$102 million. Frequent design changes and political interference created constant delays. Despite its failure as a project, the building is now a world-famous landmark.

In 1994, U.S. helicopters were accidentally shot down during a mission. Misidentification and unclear operational procedures caused the incident. Coordination between teams was weak. This illustrates the need for clear communication in complex projects.
8. Fresh & Easy Venture (USA)
Tesco Stores ČR a.s. on Wikimedia Commons
Tesco’s grocery chain failed in the U.S. due to poor market research. The company misjudged consumer preferences, leading to large financial losses. Store openings were rushed without proper testing. This example shows the risk of launching projects without understanding the target audience.
9. Airbus A380 Development Delays (Europe)
