Final answer:
The project to update a system was selected because legal regulations mandate the change. This is an essential aspect of compliance with new laws, protecting customer data, ensuring fair trade practices, or meeting environmental standards.
Step-by-step explanation:
If a system is being updated due to operating necessity, the project was selected because legal regulations mandate the update. This typically means that there is a new law or regulation requiring changes to be made to ensure that the system complies with current legal standards. Businesses are frequently required to update their systems to adhere to new regulations, to protect customer data, to ensure fair trade, or to meet environmental standards. Although aligning with strategic goals, promising high profitability, and satisfying stakeholder preferences are valid reasons for system updates too, when it comes to operating necessities, legal compliance is often the most immediate driver for a system update.
