There is no doubt that the current business climate is challenging for all companies. Zero revenue, aging receivables, payables, salaries draining cash reserves, loans not being granted and investors circling wagons and seeking loss mitigation.
Difficult times. No magical answers. I live in Upstate NY, and who knows when businesses will be allowed to open again.
Here is what I do know. This too will pass, and business will be allowed to start again some time (soon).

Here is where early and late stage can be alike: Project management planning - Ghant charts, milestones, proformas, market analysis. Now is the time to adopt simple PM processes. Mature companies must think like a startup. What will you need to ramp your business back up? How much cash will you need? What is your Burn Rate? What needs to be done to the equipment to get it ready for production. What does your supply line look like, and what will your marketplace look like? Will Demand be strong or weak? What does the market look like for the next 3, 6, 12 months? Who among your competitors might be vulnerable and open to acquisition? Who may be knocking on your door?
Opportunities for growth occur in every market, even in this current mess.
