Learning from one's mistake and adopting a new method at work is an example of what?

Correct answer: Continuous improvement

The direct answer is D: continuous improvement. Continuous improvement means regularly learning from experience, correcting weaknesses, and trying a better method instead of repeating the same mistake. The reasoning is: a mistake occurs, the worker accepts and examines it, identifies its cause, learns the lesson, changes the method, and checks whether the new method gives a better result. Option D is correct because this entire process is improvement over time. Option A is wrong because hiding a mistake prevents learning and may allow the problem to grow. Option B is wrong because blaming others avoids responsibility and does not improve the work. Option C is wrong because stopping work gives up rather than finding a better way. Learning from mistakes does not mean careless work; it means honestly reviewing what happened and using the lesson responsibly. Feedback, practice, and small corrections help a person and an organisation develop. Memory cue: notice, learn, change, check—this is continuous improvement.
