20x9

20x9 is a term used in the field of software development and project management to describe a project that is expected to take 20 hours to complete, but actually takes 9 months to finish. The term was popularized by Joel Spolsky in his blog post "The 20x9 Problem" in 2004. The 20x9 problem highlights the discrepancy between the estimated time for a project and the actual time it takes to complete. This discrepancy can be attributed to various factors such as scope creep, lack of clear requirements, poor planning, and unforeseen technical challenges. The 20x9 problem is a common issue in software development and project management, and it underscores the importance of accurate estimation, thorough planning, and effective communication throughout the project lifecycle.
