Why are additional personnel generally required during the later stages of system implementation?
According to Satzinger, Jackson, Burd and Johnson (2004), implementation consumes significantly more time and resources than the previous phases of system development life cycle. The number of people involved in implementation activities such as testing is also quite high. The interdependence between the activities involved in implementation also means that these activities have to be conducted in parallel; hence the same people cannot be used for more than one activity (Sommerville, 2000). The later stages of system implementation involve activities such as installing, testing, and transition from old system to new system. These activities are labor-intensive; hence additional personnel are required in order to organize these activities.
What are the differences between documentation for end users and system operators?
End users use the system on a daily basis, hence the documentation for end user needs should include support information about creating transactions, modifying transactions, generating reports, importing as well as exporting data and other activities that end user would be typically involved in. System operators on the other hand perform administrative functions as well as routing maintenance to keep the system operational ...
