  • Efficiency IT metrics from the table is the important to monitor, do not always guarantee effectiveness
  • For effectiveness IT metrics, it is determined according to an organization’s goals, strategies and objectives 
The amount of information that can travel trough system at                                                     any point
Transaction speed            
The amount of time a system takes to perform a transaction
System availability             
The number of hours a system is available for users…
Information security           
The extent to which a system generates the correct results                                                     when executing the same transaction numerous times
Web traffic                              
Includes a host of brenchmarks such as the number of                                                            pages views, the number of unique visitors and the                                                                  average time spent viewing a web page
Response time                      
The time it takes to respond to user interactions such as a                                                       mouse click

The ease with which people perform transactions and/or                                                          find information. A popular usability metric on the Internet                                                       is degrees of freedom,which measures the number of                                                               clicks required to find desired information
Customer satisfaction           
Measured by such branchmarks as satisfaction surveys,                                                        percentage of existing customers retained and increases                                                         in revenue dollars percustomer
Conversion rates                     
The number of customers an organization “touches” for                                                          the first time and persuades to purchase its products or                                                          services.This is a popular metric for evaluating the                                                                     effectiveness of banner, pop-up and pop-under ads on                                                           the Internet
Such as return on investment (the earning power of an                                                             organization’s assets), cost-benefit analysis (the                                                                       comparisonof projected revenues and costs including                                                            development, maintenance fixed, and variable), and                                                                  break-even analysis (the point at which constant                                                                        revenues equal ongoing costs)
