The House that Jack Built
Project management can be like building a house where everything has to happen in the right order; this is the Waterfall method.
Agile project management using software doesn’t work quite like that.
The problem with a development project is that, by the time the whole project is complete, situations have changed, new information discovered and what the management originally decided they wanted has been altered.
Waterfall projects fail 80% of the time, Agile projects succeed 80% of the time – because they’re able to respond faster to the inevitable brief changes that happen along the way.
While there does need to be an overall plan, agile project management means that each part of the project is divided up into short-term deliverables. This means that the management team can see the progress at every step and if something changes, there’s only a small step back to take.
Early failure is good – and with your budget not spent on things that don’t work it is available to spend where it delivers business benefit.
