Purpose of Implementation Convert the physical system specifications into working and reliable software and hardware Convert the physical system specifications into working and reliable software and hardware Document the work that has been completed Document the work that has been completed Provide assistance to users if system Provide assistance to users if system

4. Activities From system design to operation From system design to operation Coding, testing, and installation Coding, testing, and installation Successful operation of the system Successful operation of the system Documentation, training, and support Documentation, training, and support On-going operation of the system On-going operation of the system Maintenance Maintenance

5. Coding Process whereby the physical design specifications created by system developers are turned into working computer code by the programming team Process whereby the physical design specifications created by system developers are turned into working computer code by the programming team

6. Testing Can begin as coding for each module is completed Can begin as coding for each module is completed Modules can be tested individually and as part of the larger program Modules can be tested individually and as part of the larger program Need to determine what to be tested and collect test data during both planning and implementation Need to determine what to be tested and collect test data during both planning and implementation

7. Software Testing How to do it? How to do it? Check each module’s proper operation Check each module’s proper operation Check each peripheral (e.g., printers, scanners) to see how well it works with the software Check each peripheral (e.g., printers, scanners) to see how well it works with the software Make a list of the problems you encounter during testing and relay them to the vendor if you cannot solve them.

20. Support Answer user questions about system Answer user questions about system Assist with wide range of computer needs and system access Assist with wide range of computer needs and system access Provided through a help desk and online Provided through a help desk and online Local support Local support Vendor technical support Vendor technical support

21. Maintenance Environmental care Environmental care Endpoints of LAN (e.g., cabling) to be placed in a secure wiring closet Endpoints of LAN (e.g., cabling) to be placed in a secure wiring closet Safety for staff and users Safety for staff and users Hardware safety Hardware safety

Maintenance Environmental care Environmental care Humidity: not to exceed 80% Humidity: not to exceed 80% Hardware devices to be placed in cool and secure areas Hardware devices to be placed in cool and secure areas Hardware to be isolated from moisture, mold, and water Hardware to be isolated from moisture, mold, and water

23. Maintenance System backup System backup Back up the files daily and weekly Back up the files daily and weekly Make more than one backup copy Make more than one backup copy Keep one backup copy outside of the library/agency for security purposes Keep one backup copy outside of the library/agency for security purposes Make sure you have a UPS device Make sure you have a UPS device

24. Maintenance System security System security Install firewalls to protect the system/network from breaching into by computer hackers Install firewalls to protect the system/network from breaching into by computer hackers Install virus protection software Install virus protection software Install locking devices to prevent theft of hardware (questionable!)

Maintenance System security System security Have a security system to protect theft of materials Have a security system to protect theft of materials Use Library Technology Reports to review and evaluate security systems Use Library Technology Reports to review and evaluate security systems Vendors of security systems/devices (see Text, p. 119) Vendors of security systems/devices (see Text, p. 119)

26. Evaluation of System Use Diagnosing problems Diagnosing problems OPAC use OPAC use MARC records MARC records Circulation records Circulation records Other areas Other areas

27. Evaluation of System Use Keeping statistics Keeping statistics Collection use, circulation, cataloging, etc. Collection use, circulation, cataloging, etc. Transaction logs (OPAC) Transaction logs (OPAC) Some systems provide transaction logs of all types of searches performed in the OPAC. You will be able to extract data about successful and unsuccessful searches to diagnose problems. Some systems provide transaction logs of all types of searches performed in the OPAC. You will be able to extract data about successful and unsuccessful searches to diagnose problems.
