Problems that can happen - a tendency to spike - or 'to spike or not to spike'

The more businesses and development organisations I work with, the more I see common problem “themes”. In this series of articles I am trying to highlight the problems and show the potential solutions to some of these common symptoms.

I occasionally see a tendency in teams to attempt to spike 'everything' that is unknown to get a completely clear view for estimation or build.  In the extreme this leads to a situation where every feature is spiked to some degree before being built. Clearly wasteful.

Usually this behaviour is found in teams where for some reason either trust is low or there is a fear of failure, so tendency to spike is a protection mechanism to ensure that the team know they can deliver. More often than not in these situations the result of the spike could easily have been committed and delivered, often the result being that the estimation then becomes so low as to be trivial (because the code is in the bag), just with inevitable wasted time.

So the aim is to ensure the team feel willing to work with some unknowns - or are willing to take some risk into build. That they aren't aiming to know everything before they commit to building!

So ask if the spike is really necessary - what is the risk that means we don't think we can commit? If the risk is simply that "we can't be 100% sure we can deliver" or "we have never done that before" then you don't need a spike. If the risk is that "the world may implode" or "it may cause irreparable damage to our fragile ecosystem ultimately leading to the extinction of the human race" - then you may want to consider if a spike will actually help reduce the risk.
