(1) When you don’t communicate policies effectively, somebody else will, albeit incorrectly. This is called rumours. This is made worse during information vacuum, the period between saying you’ll announce something, and actually announcing it.
(2) Content - The government is in a position to control the narrative, avoid panic, minimise misinformation - how rumours starts. Govt also controls most media machinery - this should be simple.
(3) Audience - Govt must understand that vase majority of population are common people who are earn wages. They want to know how closures will affect them, their wages, their families. It’s day by day survival for many.
(4) Coordination - If you’re announcing something, make sure you know how to explain other aspects of life that is affected. What happens to schools? How will syallabus will be continued? How about kids with no laptops? Daycare? What if my employer refuses to allow WFH?
(5) Explain - articulate how you arrived at that decision, what considerations were taken, and ways to fix that. Assure people who are daily wage earners from their concern about loss of income. For many, not going to work daily, is a death wish itself.
