Explain the benefits of an enterprise resource planning (ERP) application to multinational organizations

ERP brings huge benefits to multinational organizations. International ERP solutions are designed to work with multiple currencies, manage international transfers of goods in inventories, and work effectively with international supply chains. Even more important, ERP solutions provide a worldwide consolidation of financial statements on a timely basis. As a result, they can produce one set of financial reports, better analyze where costs could be saved, and identify where production can be optimized. While it is advantageous for these international firms to consolidate all their operations within one large ERP implementation, called a single instance, some firms maintain multiple instances, or an ERP for each country, business unit, or region. For these firms, the advantages of one set of data, a single financial system and worldwide process standards are outweighed by the cost of consolidating or the disparity among divisions.

Explain why questionnaires are the most traceable tool for the verification of requirements

A questionnaire may be a blunt tool for gathering requirements, but is the most reliable one for verification of requirements. The reasons are:
• The definition of requirements is mature. By the time you need to verify a requirement, a valuable amount of requirements gathering has already been done. By providing a written, "black-and-white" definition that can be accepted or rejected, you concentrate the mind of the respondent. The vagueness and the blind alleys of oral discussions would not intrude.
• The flow of verification is the most traceable. The stakeholders and development team can point to an exact answer or to an exact definition as the source of their conclusions and decisions.
• Questionnaires are politically convenient. Finger pointing (or perhaps a real or an expedient loss of memory) is an unfortunate fact of any group undertaking. When things go wrong, members of the development team must be able to show that their decisions have been well-founded.
