We do not, in fact, need a new asset at all
We do not need the asset we think we do
We choose the wrong place, the wrong time for it, with too much or too little capacity
We have not considered the resources that will be needed after it is in place, including interdependencies with other assets (for example, electric buses need new facilities)
We underestimate how much it will cost to acquire in the first place; we forget other costs – such as how it may require us to upgrade other assets
We underestimate the risks in construction
We underestimate the risks in operation
We do not fully appreciate what choosing this asset, this option, means for all the things we will not be able to do, the futures that we cut off by choosing this one
The consequences of this decision spread outwards as ripples on a pond, to impact on things we maybe never even thought about.
