Study Notes
Learning Unit 2: Understanding and Modeling Organizational Systems
- This unit covers system analysis and design for understanding organizational systems.
- Organizations and their members are systems; analysts need to take a systems perspective.
- Systems are depicted graphically using context-level data flow diagrams and entity-relationship models, use cases, and use case scenarios.
- Different management levels require different systems.
- Organizational culture influences information system design.
Major Topics
- Organizations as systems
- Depicting systems graphically (Data flow diagrams (DFD))
- Entity-relationship model/diagram (ERD)
- Use case modelling
- Levels of management
- Organizational culture
Three Main Forces Interacting to Shape Organizations
- Levels of management (Strategic, Managerial, Operational)
- Design of organizations (Structure, Culture, Process, People)
- Organizational cultures
Organizations are Composed of Interrelated Subsystems
- Influenced by management decision-makers spanning horizontally across the organization; examples include operations, middle management, and strategic management.
- Influenced by organizational cultures and subcultures.
Organizations as Systems
- Designed to achieve predetermined goals and objectives.
- Composed of smaller, interrelated systems serving specialized functions.
- Specialized functions are reintegrated to form an effective whole.
- System and subsystem boundaries and environments impact information system analysis and design.
Interrelatedness and Interdependence of Systems
- All systems and subsystems are interrelated and interdependent.
- All systems process inputs from their environments.
- All systems are contained by boundaries separating them from their environments.
- System feedback is for planning and control.
- An ideal system self-corrects or self-regulates itself.
Organizational Environments
- Community (physical location, demographic profile, income)
- Economic (market factors, competition)
- Political (state and local government)
- Legal (federal, state, regional, local laws and guidelines)
Openness and Closedness
- Open systems: free flow of information, output from one system becomes input to another.
- Closed systems: restricted access to information, limited by numerous rules, information only on a "need to know" basis.
Virtual Organizations and Virtual Teams
- A virtual organization has parts of the organization in different physical locations.
- Computer networks and communication technology are used to bring virtual teams together to work on projects.
Benefits of Virtual Organizations and Teams
- Possibility of reducing costs of physical facilities.
- More rapid response to customer needs.
- Helping virtual employees fulfill familial obligations (children or aging parents).
Taking a Systems Perspective
- Allows system analysts to understand businesses before tasks begin.
- Important that members of subsystems realize interrelation with other subsystems.
- Problems occur when a manager views their department as most important.
- Bigger problems can arise as that manager advances through the ranks.
- Outputs from one department serve as input for another (e.g., marketing to production).
Perspective of Functional Managers
- In new positions, managers may continue to prioritize their old department.
- This can lead to distorted views of the company structure.
Enterprise Resource Planning (ERP)
- Describes an integrated organizational information system (software).
- Helps flow of information between functional areas.
- Includes manufacturing components, sales and operations planning, distribution, and managing the supply chain.
ERP and the Organization
- ERP affects every aspect of the organization (design of employees' work, skills required for job competency, strategic positioning of the company).
- Problems with implementation; difficult to analyze current systems and fit the ERP model to that system.
- Companies tend to design business processes before ERP implementation.
Issues to be Overcome for ERP Success
- User acceptance
- Integration with legacy systems and the supply chain
- Upgrading functionality (and complexity) of ERP modules
- Reorganizing work life of users and decision makers
- Expanded reach across several organizations
- Strategic repositioning of the company
Depicting Systems Graphically
- Context-level data flow diagrams
- Entity-relationship models
- Use case modelling
Creating Entity-Relationship Diagrams
- List the entities in the organization.
- Choose key entities to narrow the scope of the problem.
- Identify what the primary entity should be.
- Confirm the results via data gathering.
Use Case Modeling
- Describes what a system does without detailing how.
- A logical model of the system—a view of system requirements.
- Analysts work with business experts to develop requirements.
- Use cases describe actions triggered by an actor initiating an event.
Use Case Diagram
- Displays actors, use cases, and relationships.
- Actors refer to a user role.
- Ovals indicate use case tasks.
- Arrows and lines diagram behavioral relationships (connections between entities).
Four Basic Activities of Agile Modeling
- Focuses on entities and their relationships within the organizational system.
- Entity-relationship diagrams illustrate the organizational system and stored data.
- Relationships show how entities are connected (one-to-one, one-to-many, many-to-many).
Developing Use Case Diagrams
- Review business specifications and identify actors.
- Use agile stories to identify high-level events (develop primary use cases).
- Review each use case to determine variations in flow.
- Context-level data flow diagrams can act as a starting point.
Levels of Management
- Strategic management: looks outward for the future, makes decisions that guide middle and operations managers, highly uncertain environments, defines organizations as a whole.
- Operational control: makes decisions using predetermined rules with predictable outcomes, oversees operating details within the organization.
- Managerial planning and control: short-term planning and control decisions for resources and organizational objectives; partly operational and partly strategic.
Managerial Levels
- Different organizational structure, leadership style, technological considerations, organizational culture, and human interaction.
- Information system design implications across all managerial levels.
- Operations managers need low-level repetitive information, with a high dependence on current performance information (large users of real-time data).
- Middle management needs short and long-term information, real-time, and current performance information (measured against standards), and high dependence on internal information (historical for forecasting).
- Strategic management needs highly dependent on external information (e.g., market trends, competitor strategies), and predictive information for future projections.
Organizational Culture
- Organizations have cultures and subcultures.
- Learns from verbal and nonverbal symbolism.
- Culture is amplified by leadership behaviors, evident in individual and group behaviours.
- Embedded in organizational practices (shared beliefs, values, and assumptions).
- Visible in daily work practices.
Verbal Symbolism
- Myths, metaphors, visions, humor.
Nonverbal Symbolism
- Shared artifacts (trophies, etc.), rites/rituals, promotions, birthdays, clothing, office placement/decorations.
Summary
- Organizational fundamentals (organizations as systems, levels of management, and organizational culture).
- Graphical representation of systems (DFD, ERD).
- Use case diagrams and scenarios, levels of managerial control (operational, middle management, and strategic), and organizational culture.
