In this article, the author discusses the importance of completing the last 1% of a software project. They emphasize that many projects claim success and move on to the next thing when they are almost done, but fail to complete the final 1% of the work. This last 1% is crucial as it separates a great product from a good one and determines whether a product will eventually fail or not. The author lists several things in this last 1% that are frequently overlooked, such as internal and external documentation, performance metrics, usage metrics, error metrics, alerting, and automated testing. They acknowledge the temptation to move on to the next project after months of hard work, but urge readers to take the time to finish the last 1% as it is worthwhile.
