As part of the research I currently working on (looking at the case for Portfolio Management, what does ‘good’ look like, and how should we measure it?) I’ve been pondering a question – why is it that even when the analysis has been provided, governance bodies have been slow to take action with failing projects continuing to be funded long after it was clear they should have been killed?
One thought did occur to me – on the one hand evidence shows that a key success factor in projects is the level of stakeholder commitment, but on the other hand we don’t want this commitment to blind managers to emerging new evidence that affects the case. Yet humans are often not very good at updating their positions to reflect new evidence. The problem is that our commitment, that we believe to be based on a rational analysis of the situation, quickly becomes an emotional commitment that is relatively impervious to new evidence. As Ian Ayres says in ‘Supercrunchers, Why Thinking-By-Numbers Is the New Way To Be Smart’, “humans not only are prone to make biased predictions, we’re also damnably overconfident about our predictions and slow to change them in the face of new evidence. In fact, these problems of bias and overconfidence become more severe the more complicated the prediction.”
Being aware of this helps, not least in highlighting the importance of making the right decisions as early in the pipeline as possible – killing failing and non-strategically aligned projects is a success not a failure, but only if the decision is made as early as possible. Another defence against such optimism bias are regular ‘stock takes’ with robust, independent scrutiny to ensure that the investment justification stills holds true. But why don’t we shift the basis of presumption – so that if a project goes outside tolerance, the assumption is that funding will be cut? Funding may of course still continue, but the case for this needs to be made. This is more effective than the reverse where failure puts funding at risk, but unless positive action is taken, funding continues.
