Four points does not a triangle make. We often hear in PM classes about the triangle of doom...scope, cost and time and that a change to one impacts the other and they all impact quality....well, I often think about this triangle thingy and always see how wrong it is. A project is made up of scope (work to do), resources (people doing the work) and quality (how good the work turns out) - each of which impacts and is impacted by cost and time - AND - in addition to this theory layer there's also real world considerations such as skill sets, communication, external business forces, politics, etc. that often have as much impact on a project. So, what I think I'm getting to is that the triangle is inconsistent with even the base PM focus areas and does not take into consideration other factors. If a map does not correctly define the landscape then it becomes more of a cause for problems then a solver of one. I think it's time we think of a new metaphor for PM - the PM triangle needs to be put away and forgotten about.
