issues should be included in this analysis:
             • Methods and formats of data input
             • Significant operating constraints (workload volume, users: skills, hardware limitations, security and backup)
             • Interfacing possibilities with existing hardware and software
             • Processes and costs of converting existing data

             • Vendor –support requirements
             • Flexibility and expandability requirements
             • Required hardware configurations
