Steps in System Implementation: Coding Coding Testing Testing Installation Installation Documentation Documentation Training Training Support Support Maintenance Maintenance Evaluation Evaluation

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 of system Provide assistance to users of system

Operations to Understake 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

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

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

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.

Approaches to Installation Direct installation (for new system) Direct installation (for new system) Parallel installation (old and new system coexist) Parallel installation (old and new system coexist) Single location installation (pilot approach by selecting pilot sites) Single location installation (pilot approach by selecting pilot sites) Phase installation (staged, incremental based on system functional components) Phase installation (staged, incremental based on system functional components)

Documentation Two types Two types System documentation System documentation User documentation User documentation

System Documentation Detailed information about a system’s design specifications, its internal workings, and its functionality Detailed information about a system’s design specifications, its internal workings, and its functionality Internal (part of the program source code) Internal (part of the program source code) External (all diagramming techniques such as data flow diagrams and entity relationship diagrams) External (all diagramming techniques such as data flow diagrams and entity relationship diagrams)

User Documentation Manual containing information about how the application system works and how to use it. Manual containing information about how the application system works and how to use it. May include all or most of these: May include all or most of these: quick reference guide, user’s guide, release description (for a new version), system’s administrator’s guide, index, help, etc. quick reference guide, user’s guide, release description (for a new version), system’s administrator’s guide, index, help, etc.

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

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.
