In-Depth Information
companies and banks that maintain data for long periods of time. In addition to the
type of organization, other factors that contribute to a challenging effort include the
size of the fi rm, whether the data are already available in a computer-readable form
and whether existing data are in the format required by the new system. For projects
with complex data efforts, fi rms often outsource the development activity.
2.9.3 Install Any Required New Hardware and
Connectivity
Planning for acquisition of additional hardware should begin early in the project so
that the hardware is delivered, tested, and available when needed. Some new hardware
might be needed as early as unit testing in the preliminary construction stage. Consid-
erable lead time needs to be expected in order to identify potential hardware vendors,
get competitive bids, complete the purchase, and physically receive the hardware.
2.9.4 Make Available the Physical Facility
Planning for any construction of new or remodeled facilities must also begin early
in the project. Preparation of facilities for large-scale systems demands inclusion of
features that provide for the necessary temperature and humidity controls, pollutant
controls, uninterrupted power, fi re detection and suppression, and security mea-
sures. Such communications-oriented systems as local and wide area networks add
still another layer of complexity and importance to physical facility planning and
construction.
2.9.5 Test the Hardware Configuration
Common hardware tests include testing the system to ensure its ability to access data,
process data, communicate with other hardware, and handle forecast peak loads.
2.9.6 Complete the Documentation
As the project has unfolded, documentation has been added to the project diction-
ary. The conclusion of the Final construction stage is a good point to complete any
process and data models and other documentation that will be necessary for any
future system revision or reengineering efforts. This is also the time that the training
material and operation guides are written and published.
2.9.7 Gain User Acceptance to Go Live
During this activity, the system components are installed; the user acceptance test
is designed and conducted. The user acceptance test is the fi nal test of the system to
determine whether it meets the users' perceived needs. Acceptance by both users
