The four components of pre-trial preparation are as follows:
1) Case File Organization - file should be cleared of clutter and contain only pertainent information
2) Investigation and Discovery- Investigation includes information obtained from, but not limited to, state and local police reports. Discovery is information procured from the other side.
3) Analyzing and Interpreting - all of the information you've obtained from investigation and discovery must now be evaluated for its usefulness
4) Case Theory Development - You should be able to explain to anyone the nuts and bolts of your case in under a minute. Consider this your "thesis" that has been formulated after you have done all your research.
