Some tasks will require a keener eye and additional diligence. Being able to distinguish which tasks require extra attention speaks to your ability to prioritize and manage your time. Some might procrastinate tasks that they dread by finding excuses to keep working on a project that is already good enough. So make sure, while presenting your example, that it reflects holding the interests of the team above your interests. There's nothing wrong with showing initiative, so long as it benefits the team. Discuss a time when you were extra thorough in completing a work-related project.
