System Implementation Flashcards
begins early by preparing staff and users for changes. An implementation committee should be formed before purchase of a system to assess needs and ensure that changes meet the mission of the organization.
System implementation
new system may involve phasing by module, unit, or geography.
Phased implementation
occurs when a complete system goes live across an organization on a designated date and time
Big Bang Implementation
often used in large organizations or those with multiple locations to “try out” the new system before it is implemented further.
Pilot implementation
both the existing (legacy)system and new system are used concurrently
parallel implementation
allows end-users to learn the new system while still using the old system to record data.
parallel implementation
In order to assure that business processes are maintained.
Hospital administration
To assure that billing and patient records are maintained, in addition to establishing a budget.
Finance
To facilitate that nursing procedures are compatible with the new system.
Nurse Administration
To oversee that the system is installed properly.
Director of Information Systems department
To assure that record keeping is accurate and follows all regulatory requirements (e.g., HIPAA)
Medical Records
involves understanding the types of resources available—educational, personnel, financial, and equipment—as each must be allocated, using different priorities;
Assigning resources
software upgrades, new software, and new hardware, is almost constant, but constant changes to a system can result in changes in functionality and a need for increased resources and training.
System enhancements
The following steps are involved in administering the system implementation process
Develop a schedule
Assign tasks
Establish communication
Test the system
common with information systems because of updates, upgrades, and the addition of new features.
Programming changes
Typically, software upgrades are released on an _________ schedule, and often one upgrade can be skipped without a significant impact on productivity
18-month
cannot occur without organizational change
Performance Improvement Processes
common for many people, so coordinating collaborative processes requires anticipating resistance and taking steps to achieve cooperation.
Resistance to change
should be evaluated and satisfied before the new system is installed:
Hardware infrastructure requirements
able/wireless local area network (LAN) installation, available access points, and overall compatibility with the new system.
Network infrastructure
(desktop computer, laptop computer, terminals, etc.).
Types of user workstation interfaces
portable or permanent
location of the workstations
servers
Location of the hardware
occurs when data are translated from one format to another
Data conversion/ migration
must occur for the new system to use legacy data but may also occur during system hardware/software upgrades
Data Migration
The primary stages to migration of data include
Planning stage
performance stage
validation stage
This includes inventorying the system, reviewing the types and amounts of data to be migrated and the source and destination formats, determining the most cost-effective method, making a specific plan for conversion, performing mapping, and creating conversion scripts and specification documents.
Planning stage
This includes generating baseline backup of all data, extracting data from the source, normalizing data, performing trial and test conversions, and completing data migration.
Performance stage
This includes checking to ensure data were converted accurately and completely with all data elements formatted correctly, eliminating duplicate data, and resolving problems.
Validation Stage
the ability for two systems to exchange and use data while maintaining the same meaning, and this is an important element in the conversion of data.
Interoperability
refers to the ability of two systems or equipment from different manufacturers to exchange data
Technical interoperability
This usually refers to hardware/software or equipment that allows machine-to-machine communication.
Technical interoperability
refers to the transfer of data formats without necessarily ensuring that meaning is intact.
Syntactical interoperability
refers to the transfer of meaning so that people recognize that the content transferred is the same.
Semantic interoperability
refers to processes and specifications that facilitate exchange of data from one organization to another.
Process interoperability
offload data from the main storage system in an accessible format (online or offline).
archive legacy data
comprised of a director and support staff, can coordinate and monitor all operations (e.g., applications, user support, vendor support, communication, documentation, technical operations).
Command center
should be established as part of the preliminary planning.
Command Center
Three primary functions of the command center include:
Providing communication
Exercising control
coordinating all activities
In order to integrate computer systems, two major items of importance are
Data Dictionary and a Master patient index
lists commonly used terms, their definition, and their synonyms.
Data dictionary
lists all patients and their demographic information.
Master patient index
interface connects two separate systems directly to each other.
Point - to - point
For systems that need to interface with more than two entities, it is best to use an interface engine software.
Software reliance systems
occurs at the end of the day when all information is transferred at one time.
Batch processing
can process information in real-time or in batches. Real-time processing means that information is transferred from one system to another immediately.
Interface engine software
