For example, the instructions involved in updating financial records are very different from those required to duplicate conditions on an aircraft for pilots training in a flight simulator. More complex ones may require more than a year of work, while others are never considered ‘complete’ but rather are continuously improved as long as they stay in use. In most cases, several programmers work together as a team under a senior programmer’s supervision.
