picture of an issue.
ii. Information should be reliable.iii. Information should be valid to the purpose for which it will be used.
iv. Appropriate level of quality of information should be maintain.
v. Data redundancy should be avoided

Decision making under certaintyis possible when decision maker has full knowledgeabout the alternatives and its outcomes (known as Perfect information).
In uncertain situations, the decision maker requires additional information to takemore accurate decisions. If this additional information wipes out uncertainty or riskcompletely then it is calledperfect information.
In organization, Managers play a key role in decision making for this informationsystem have become the main tool.

Identification of Costs and Benefits
In this step, the different cost and benefit associated with the information system.
Tangible and Intangible Costs and Benefits:
Tangible Cost: Payment of Cash like hardware/software purchase
Tangible Benefit: Reduced time in preparing a report
Intangible Cost: Cost of breakdown of an on-line system during banking hours willcost lose of deposit and human resourceIntangible Benefit: Higher customer satisfaction or improved business image.

1. Discounted cash flow criteria: in this future cash inflows (earning frominvestment ) are discounted to make these comparable with present dayinvestment.
2. Non-Discounted Cash flow criteria: no such discounted is made.

Quantitative and Qualitative cost benefit analysis
In Quantitative cost benefit comparison which expresses all costs and benefits inmonetary terms, compares costs and benefits by summarizing the ratio of benefitsby summarizing the ratio of benefits to costs.
In Qualitative cost benefit analysis differs from quantitative cost benefit analysis in
drawing on a range of evidence of costs and benefits, not all cost and benefits canbe converted to monetary value.
Quantitative Benefits are: Reduced costs, reduced staff, increase productivity
Qualitative Benefits: Improved public performance, increased work satisfaction,
improved management, better time management
