What would a plan look like?

I have been looking around at different town websites and I have come across a financial forecast on the Town of Barnstable site that contains the elements that I think the financial plan mentioned in the Town Charter and DOR report envision. The link to...

... that report is here. Obviously something like this takes a good deal of time to prepare. However once done, it can be updated with much less work. I would like to emphasize that having this plan does not solve any problems. It just allows us to recognize and react to issues that the forecasts seem to present. As with any plan, the reality of what actually happens is changing and so then the plan must change. This is not a failing. A financial forecast is a tool, not an end in itself.
By the way, the Town of Barnstable website is great and is a model for what I would like the Town of Dartmouth site to be. Take a look at it here. It has a wealth of information, even video of all the various meetings under the Video on Demand tab at the left.
When I first was in charge of starting up power plants, the schedule was a huge document that took many weeks to compile and revise. But half way through the project, due to late delivery of components and construction delays, the original plan bore no resemblance to what had actually happened or was going to happen. But because it took so long to revise and produce, it wasn't changed. Computers and software changed all that. By linking tasks to their precedents and antecedents, we could input the delays and see how that affected the overall plan. Then we were able to come up with work arounds for some issues that helped to return us to our schedule. The same thing is possible with a financial plan. Some items will increase more than expected, some less, and by inputting that into our plan, we can see the impacts and try to find ways to accommodate them.
