2.1 You are tasked with planning of maintenance tasks at a water treatment facility. Acritical pump has failed unexpectedly, causing significant downtime. Meanwhile, another pump of the same type has been operating without any issues.

2.3 At a manufacturing facility, operators are primarily responsible for running production equipment, while the maintenance team handles all repairs and upkeep. Recently, the facility has experienced an increase in unplanned equipment downtime due to minor issues that could have been detected earlier. Explain why should the operator be involved in the maintenance of physical assets? (3)
2.4 What are the consequences of poor preparation of maintenance tasks? Illustrate this by means of five examples. (5)
