Study Notes
Organizations as Systems
- Organizations are designed to achieve predetermined goals and objectives
- Consists of interconnected subsystems specialized in certain functions
- These functions are reintegrated to form an effective organizational whole
- All systems and subsystems are interrelated and interdependent
- Systems process inputs from their environments.
Enterprise Resource Planning
- An integrated organizational information system
- Helps the flow of information between functional areas within the organization
- Recent ERP systems are transitioning to cloud computing
- Includes manufacturing components, sales and operations planning, distribution, and supply chain management
- Difficult to fit the ERP model to existing systems
- Implementation often requires redesigning business processes before ERP is implemented
Influences of ERP
- Can affect every aspect of the organization, including employee work design, required job skills, and strategic positioning of the company
Challenges of ERP Implementation
- User acceptance is critical for success
- Integration with legacy systems and the supply chain is crucial
- Upgrading ERP modules requires careful consideration of functionality and complexity
- Reorganizing work life for users and decision makers is necessary
- Requires reaching across multiple organizations
- Must be accompanied by strategic repositioning of the company
Graphical Depiction of Systems
-
Context-level data flow diagram: Focus on the data flowing into and out of the system and the processing of the data. It defines the system's scope, including what's included and what external entities are outside.
-
Entity-relationship model: Shows the relationships between entities and their attributes.
-
Use case modeling: Depicts the interactions between actors and the system.
Understanding Use Case Relations
- Include: Indicates that one use case includes the behavior of another.
- Extend: Describes a scenario where one use case handles a variation or exception to a basic use case.
- Generalize: Implies that one use case is more typical than the other.
Defining Scope in Systems
- System scope defines its boundaries, encompassing what is included and excluded from the system.
- Project budget and project timeline factors into scope.
- Actors are always outside the scope.
- Communication lines define the boundaries and scope of a system.
Developing Use Case Diagrams
- Identify the actors involved
- Identify high-level events and develop primary use cases that describe those events and how actors initiate them
- Review each use case to determine possible variations in the flow through the use case.
- The context-level data flow diagram can serve as a starting point for creating a use case.
Understanding Use Case Scenarios
- Describes the use case in detail.
- Three main sections:
- Use case identifiers and initiators
- Steps performed
- Conditions, assumptions, and questions
Use Case Header Area
- Contains the name and unique ID of the use case.
- Includes the application area, actors, stakeholders, and level.
- Provides a brief description of the use case, including the triggering event and type of trigger (external or temporal).
Understanding Use Case Levels
-
White (Enterprise Level): Covers the entire organization with a limited number of use cases. These use cases typically execute over long periods, such as days, months, or years.
-
Kite (Business Unit Level): Depicts use cases at the business unit or department level, summarizing overall goals.
-
Blue (User Goal Level): Represents user goals. Typically used for business activities that can be completed within a short time frame.
-
Indigo (Functional or Subfunctional Level): Provides detailed descriptions at a functional or subfunctional level.
-
Black (Subfunction Level): Offers the most detailed descriptions at a subfunction level.
Management Levels and Information Systems Development
-
Operations managers: Require internal information that is repetitive, low-level, and captures current performance. They use a high amount of online real-time information resources.
-
Middle management: Need both short and long-term information. They require real-time information, comparing current performance to set standards.
-
Strategic managers: Heavily dependent on external information for market trends and competitor analysis. They need information that allows for predictions, accurate risk assessments, and periodic reports.
