A software package developed to handle information requirements for a specific type of business is called a(n) _____.
Mission-critical IT systems should be outsourced only if the result is a cost-attractive, reliable business solution that fits the company’s long-term business strategy and involves an acceptable level of risk.
Compared with software developed in-house, a software package is almost always more expensive.
Outsourcing is the risk free approach since someone else does the work.
Typically, a physical design describes the actual processes of entering, verifying, and storing data; the physical layout of data files and sorting procedures; the format of reports; and so on.
A logical design defines what must take place, not how it will be accomplished. Logical designs do not address the actual methods of implementation.
Outsourcing also can raise numerous issues including security, confidentiality, quality, insurance, potential liability, licensing, information ownership, warranties, and disaster recovery.
Moving IT work overseas raises even more issues, including potential concerns about control, culture, communication, and security.
You never create both a logical and a physical design for the same project.
A physical design is like a set of blueprints for the actual construction of a building.
Cost-benefit analysis determines how long it takes an information system to pay for itself through reduced costs and increased benefits.
