Is there one? One quality which is more valuable (and therefore more necessary) than others.
Well, that is not a simple question. All businesses need a variety and a numb er of qualities to go successful through their start-up phase and then perhaps a different (though overlapping) set of qualities for their 'stablisation' phase, their growth phase - and so on
However, through each of these phases, perhaps one specific quality is more valuable than others.
Then, we get the situation where the external context (the business environment) makes a particular quality more important.
As of now, all businesses are facing threats from technology (and specifically AI). Ironically the threat posed by AI is even applicable to AI companies themselves. (The biggest threat is faced by those whg don't think they are facing a threat.)
In situations where there is a generic, external threat (and especially where that threat is only partially understood) all businesses need the essential quality of remaining flexible. This can be called flexibility, agility, resilience or ….. but it is the ability to 'read' the situation and take appropriate action. This will depend on the market the business is in - but act it must.
So, all businesses should currently be reading their own situation snd the external factors that are in play (and how these relate to the business and the way it operates). You should be getting ready to act - even if tyou are not yet quite ready to act.
Is your business agile enough to survive?
