Dimensions of information systemsEncompass the understanding of the management and organisational as well as the technical dimensions of systems.Organisational• Information systems are an integral part of organisations and automate many business processes.• Various levels in an organisation create different interests and point s of view resulting in conflict on how the organisation should be run and how resources and rewards should be distributed.
Management• Manager set organisational strategy for responding to challenges and allocate human and financial resources to execute the work and attain success ensuring responsible leadership.• An important part of management is creative work driven by knowledge and information assisting managers design and deliver new products and services.Information technology• Is a tool that managers use to cope with change.• It entails computer hardware, computer software, data management technology, networking and telecommunications technology.• Internet technology is both a business necessity and competitive advantage for most companies.
• The IT infrastructure provides the foundation or platform on which a company can build its information system. Laboratory information system (LIS)• Is software that records, manages and stores data for clinical laboratories.• Is sending laboratory test orders to lab instruments, tracking those orders and recording the results to a searchable database.
• It’s commonly used in health care setting for time and data management functions.LIS functions• Patient data tracking• Quality assurance• Analytical reporting• Workflow management• Billing• Third party software integrationTwo broad categories of LISClinical pathology• The chemical, hormonal and biochemical components of body fluids are analyzed and interpreted to determine if a disease is present.Anatomic pathology• Tends to focus on the analysis and interpretation of a wide variety of tissue structures, from small slivers via biopsy to complete organs from a surgery or autopsy.These differences may appear to be small, but the differentiation in laboratory workflow of these two medical specialties has led to the creation of different functionalities within LISs. Specimen collection, receipt, and tracking, work distribution, and report generation may vary sometimes significantly between the two types of labs, requiring targeted functionality in the LIS.
