Scale can loosely be defined as the quantity of folks focusing on a project. It ought to be considered at the outset because the value of project administration will increase exponentially with the quantity of individuals concerned. Project administration may very well be trivial for a small project but for those who expect it to mature, employing a structured workflow early could steer clear of problems afterwards. On modest projects consisting of a ‘one off’ script, project management may be a distracting waste of time.
