Obviously the ongoing operation of a Web site will consume the greatest amount of staff time and effort. Web site development is labor intensive because of the many decisions that need to be made to effectively design the Web site. Program evaluation and Web site Integration are the next most labor intensive due to the amount and complexity of the data involved and the critical thinking necessary to make good decisions. Finally, staff training, trial use, and evaluation are well-focused activities that are less labor intensive in comparison with the other steps in the implementation process. Feedback loops .
Implementation is a dynamic process.
Staff need to respond to feedback as the implementation process continues. Data obtained in a particular step may indicate that a previous step needs to be at least partially repeated to ensure effective Web site implementation. The feedback loops in the present implementation model are indicated in Figure 1, with arrows indicating the direction of the feedback. The continuing nature of implementation . Implementation is an on-going process.
