5. Comparison tables

Tables are also very effective at comparing the old system to the new one.

For example, the table below highlights some characteristics of old and new system

Current System	New System
Input form is processed in 10 minutes	Input form is processed in 5 minutes
Cannot create a PDF document	Will create both printouts and pdf documents
Has 20 Gigabytes of memory	Has 200 Gigabytes of memory

A good comparison should always be measurable so that the benefits are clear.
