Implementation is the realization of an application, or execution of a plan, idea, model, design, specification, standard, algorithm, or policy.
IT Implementation and the Role of End users
System implementation generally benefits from high levels of user involvement and management support. User participation in the design and operation of information systems has several positive results. First, if users are heavily involved in systems design, they move opportunities to mold the system according to their priorities and business requirements, and more opportunities to control the outcome. Second, they are more likely to react positively to the change process. Incorporating user knowledge and expertise leads to better solutions.
The relationship between users and information systems specialists has traditionally been a problem area for information systems implementation efforts. Users and information systems specialists tend to have different backgrounds, interests, and priorities. This is referred to as the user-designer communications gap. These differences lead to divergent organizational loyalties, approaches to problem solving, and vocabularies. Examples of these differences or concerns are below:
- Will the system deliver the information I need for my work?
- How quickly can I access the data?
- How easily can I retrieve the data?
- How much clerical support will I need to enter data into the system?
- How will the operation of the system fit into my daily business schedule?
- How much disk storage space will the master file consume?
- How many lines of program code will it take to perform this function?
- How can we cut down on CPU time when we run the system?
- What are the most efficient ways of storing this data?
- What database management system should we use?
