So is project management an art or a science? The truth is probably that it is a bit of both. There is definitely a fair amount of science and a comprehensive set of tools and techniques associated with the topic. However, the art is related to the people element of project management and this is where the challenges and opportunities lie. If you can scope and plan effectively then that is a great first step, but where you really show your project management expertise is to bring together and motivate a skilled team of people who deliver on time and within budget.
