I will answer this question from a different angle. From a business plan and technical point of view, a DR plan should have already been in place. Thought must be given to each point of failure. If a plan is not in place, yes, it should be in development now. Brainstorming with your team as to different failure scenarios and planning for contingencies is key. In some instances, your product or service simply cannot be supported in a disaster such as this. But if you can source product differently, ship it differently, offer it to your customers differently, provide support differently, these plans will provide a better chance of survival. If applications, processes, technology are required, it's better to have a plan & implement, but if you do not, it's not too late. You may experience challenges in procurement/availability, time to deployment of these plans as you are competing with others for the same resources, but better to proceed. ie. a restaurant - if you wish to offer curbside or carry out during the pandemic - what menu options work best in that scenario? How will customers order and pay? how will you safely staff? What is the status of your supply chain? Are you prepared to accept different payment methods? There are so many questions & those are just quick examples. Lastly, as soon as you are stable, try to prepare for the return to whatever 'normal' may be the next step. Staffing, transition, hours, AP/Payroll etc - your transition back will be smoother.
