Instead, you should schedule the project in complete phases. Intermediate milestones, spaced no more than about two weeks apart in a medium to large project, should include specific goals for the model, animation, data, and analysis. By the time you reach the last 25% of your time on the project, you should have addressed the basic analysis issues of run length, warm-up time, etc. and should already have performed preliminary analysis on the model for a number of different scenarios. |
