Research on the Operation & Maintenance Model of IT Project

The O&M (Operation & Maintenance) phase of IT project is the phase when IT project yields economic return or performs its function and the owner gains the interest. Whether the investment and construction of IT project is successful or not depends on the result of the maintenance. Moreover, the selection of IT project O&M model has an important effect on the efficiency of IT project O&M. The traits of IT operation and maintenance are analyzed from the owner's aspect. Besides, we research the traits, advantages and disadvantages, and scope of application of the three models: self-O&M model, outsourcing O&M model, mixed O&M model. Based on these, we compare different models and then study the chosen time and foundation of the IT project O&M model.
