At this point, it's not a question of if lockdown happen again. It's about when and how long. Lockdown will continue to happen from time to time until everybody get vaccinated. It's just a matter of location and severity.
As such, it's a good time to evaluate how fragile is your business supply chain. Can you get all the supplies if faced with interstate lockdown? How about interdistrict lockdown?
Could you get an alternate supplier? Or could you change your product to be less reliant on faraway supplier?
Even more dramatic - should you consider a different business altogether?
