A company is rewriting its payroll system to move it from an old batch-type mainframe to a distributed mini-computer/PC-based networked setup. No new functionality will be added.
The statement of work calls for a conversion "as is." Only the input and output subsystems will be altered for the new environment. Since it is a payroll application, testing and verification will be emphasized within the development activities. The schedule allows five months for the project, with two people working on it.
