The most significant ongoing challenge of COVID-19 is that it is.... ongoing. Fatigue is a genuine concern for businesses, especially as we now deal with a second surge in VIC - we all just want this to be over. There is a requirement to continue to assess impacts on businesses and not become complacent - the management requirements may not be the same as we move ahead. Because a strategy worked in March/April does not necessarily mean it will work in July/August.
There may also be a need to rotate managers out of positions of COVID-19 response management to give them a break and mentally recharge for the challenges ahead. This obviously requires detailed notes and handovers to ensure continuity of response.
