Final answer:
A survey extension may be granted in cases of unexpected staff absences or resignations and during software conversions, both of which can disturb normal operations and data collection processes. These circumstances justify an extension to ensure accurate survey results and account for delays or training needs.
Step-by-step explanation:
A survey extension may be necessary in certain circumstances to ensure accurate and comprehensive data collection. In the case of unexpected staff absences or resignations, an organization may need additional time to recruit and train new personnel, thereby justifying an extension. Similarly, during software conversions, there may be technical delays or learning curves associated with new systems that could impede the survey process. These scenarios both lead to interruptions that could justify an extension of a survey period.
