Ha. There are three kinds of contingency: 1) Explicit Contingency - These are line items in the labor plan and/or Expenses called Contingency that are to be used under certain circumstances. The amount of contingency should be determined proportionally to the quality of the forecast. If the forecast is shaky, you need more contingency. If it is something you do a lot, and experience shows your forecast is spot on, you don’t need much contingency; 2) Implicit Contingency - This is where PMs bury contingency in their plan - good luck finding it. If the designer says it will take 100 hours to produce something, the task plan magically shows 150 hours. Review tasks might have 10 hours, when they really only need 5. I used to take estimates from software developers and triple it in my plan - I never trusted the accuracy of their forecast, so I buried my risk mitigation strategy (contingency). 3) Untouchable Contingency - This is contingency built into a project that a PM can’t use. Our fixed assets team, for example, builds in 5% contingency for their purposes. The PM can’t touch it. That contingency, however, appears on all their financial reports, so we are incessantly explaining how our numbers won’t match their numbers, because their contingency isn’t a project cost, and so on. When I worked in Marketing running projects, we always added a modest contingency, but called it something like “Minor Adjustments and Changes”. That way, when you get someone who wants ten revisions of a particular bit of content, you’ve got that covered. You would expect three or four, but sometimes people can’t make up their mind and you can’t predict when that will happen. I can’t imagine running a project with total confidence that the forecast is bang on. If someone could forecast a project and not need any contingency, their prognostication skills could be put to more profitable use in the Stock and Securities market. ☺ Eric
