What are some rules of thumb that you use to do a rough schedule estimate (guess) for an initial project evaluation? An example might be for every week estimated to work out requirements then allow 2 weeks for development and 1 week for user acceptance. Saving Changes...

Most people make a rule-of-thumb schedule based on experience from previous similar project and make adjustment if this project is more complicated or not. If the Project Manager does not have the experience it is worth asking someone else with the experience. Saving Changes...

Thanks Dominic, I agree that this is a good approach.
However sometimes there is an idea that is sufficiently outside of past experience or rare enough that it's not possible to take a previous project and plus/minus a complexity factor, so I am interested in additional approaches to guide the guess without requiring significant analysis.
But complexity is a relevant factor. Saving Changes...

No matter the rule of thumb you will use you have to take into account some method to calculate deviation and to define how you will publish your estimations. My recommendation is see Barry Bohem´s "Cone of Uncertainty". While is a tool created for IT and software project it could be used into any type of projects. Saving Changes...

Thanks Sergio.
The pictorial representation of the cone is particularly helpful, although not always will accepted by project sponsors! :-) Saving Changes...
