2 What is a System? • It is a whole with a purpose and has interacting, interdependent parts. • Parts cannot provide system function, examples: Wheels alone cannot carry passengers from points A to B, but the whole car does. • Implementing solutions with a limited understanding of a system and its interactions with larger systems can lead to unintended consequences with time delays • Examples: Traffic congestion, air pollution, siloed information systems, siloed professional practice Air pollution = large scale disaster Traffic jam = nuisance of urban life Car = technological feat 17
An Information SystemPeople, Process and Technology • The system that captures, manages, analyzes and uses information is made up of people, process and technology. • Alignment of all three enables smooth functioning of the IS. • Alignment with organizational context enables IS to deliver impact to organization bottom line. 18
DISC: Data, the Information Systemand its Context Knowledge about systems comes from various disciplines. • Context components: • Environment: Technology trends and advancements, socio-cultural factors, health system factors, legislation, other information systems, other systems • Organization: Mission, structure, resources information culture, values, informatics capacity, programs and policies • Information system components (structure): • People: End users, system administrators, decision makers • Process: Business activities supported by information system • Technology: Paper, computing and communication devices, communication networks, software applications that support information management • System interactions: • Both environmental and organizational contexts affect how information systems are designed, developed, implemented and used. • Organizational performance can be a cause or a consequence of information generation and use, and vice versa (reinforcing loops). Information System Data Context • Data: • Data • Information • Knowledge Adapted from (1) Heeks R, Bathnagar S. Understanding success and failure in information age reform.

Layers of InteroperabilityAlignment challenges • Human-to-human interoperability as important if not more than machine-to-machine interoperability. • Corresponding layers may be asymmetrically developed 25
Informatics Problem Solving A Systematic Approach to Apply Knowledge to Real World Issues • A problem is defined as a recognized gap between a current state and a future state. Problem solving is a systematic approach to get to the future state. • From a living systems perspective, an informatics problem is like a “disease” or disorder within an information system that prevents creation of value. • There may be organizational or environmental determinants that lead to development of informatics problems. 26
Information “Pathologies” • Preventable gaps in distributed information processing • When Information that can be applied to a decision-making process is: • Producible and not produced • Procurable and not procured • Transmissible and not (accurately) transmitted • Applicable and not (accurately) applied Scholl W.
