ISO 31000 and the PMBOK Guide both stress the need for a balanced approach in multinational or complex projects: processes must provide structure and consistency across the organization while remaining flexible enough to accommodate local differences and dynamic risks. This is especially important in projects with varied regulations and stakeholder priorities.
"The organization's risk management framework should be customized and proportionate to the organization' s external and internal context related to its objectives... combining structure for consistency and flexibility to adapt to specific circumstances."
- ISO 31000:2018, Section 5.3 (Framework and Customization)
"Risk management planning should reflect both organizational standards and the specific needs of the project, ensuring consistent practices while retaining flexibility for adaptation as needed."
- PMBOK Guide, 6th Edition, Section 11.1
Therefore, developing a strategy that combines structure with flexibility (Option B) is the best practice.
