Study Notes

System Design

The process of defining the architecture, components, modules, interfaces, and data for a system
Translates requirements identified during analysis into a blueprint for building the system

Key Activities

Architecture Design: Defines the overall structure, including hardware, software, and network components
Detailed Design Specifications: Creates detailed documents outlining how each component functions
Database Design: Designs the schema and data models to support data storage
User Interface Design: Designs user interfaces that are intuitive and user-friendly
Prototyping: Develops prototypes for visualization and stakeholder feedback
Integration Planning: Plans how different system components will interact with each other and existing systems

Relationship Between System Analysis and System Design

System analysis precedes design, identifying what the system needs to do.
Design focuses on how to achieve those requirements.
The analysis findings inform design decisions.
Both phases produce documentation that serves as a reference and guides the development process.

Major Components of a System

Interrelationships: Components are interconnected, meaning one component's state can affect others.
Purpose: Every system is designed to achieve a specific goal.
Inputs and Outputs: Systems receive inputs from the environment, process them, and produce outputs.
Feedback Mechanisms: Systems can adjust and adapt based on their outputs to maintain stability or improve performance.

Types of Systems

Open vs. Closed Systems: Open systems interact with the environment, closed systems do not.
Physical vs. Abstract Systems: Physical systems have tangible components while abstract systems involve concepts, processes, or methodologies.
Simple vs. Complex Systems: Simple systems have fewer components and interactions, while complex systems have many interrelated parts and behaviors.

Types of Information Systems

Transaction Processing Systems (TPS): Handle day-to-day transactions (sales, receipts, payroll, inventory) and process large volumes of routine transactions.
Management Information Systems (MIS): Provide managers with tools to organize, evaluate, and manage departments. They generate reports based on data from TPS and aid in decision-making.
Decision Support Systems (DSS): Analyze large volumes of data and provide insights to support complex decision-making.
Executive Information Systems (EIS): Systems designed for senior executives, providing easy access to internal and external information relevant to their strategic goals. They often feature dashboards and visualization tools.
Customer Relationship Management Systems (CRM): Help organizations manage interactions with customers. They store customer data, track sales, and manage marketing campaigns.

Boundaries

Every system has defined boundaries that distinguish it from its environment.

Environment

Systems exist within an environment that can influence their operation.

Hierarchy

Systems can be organized into hierarchies, with larger systems composed of smaller subsystems.

Equifinality

A system can reach the same final state from different initial conditions and through different paths.

Players in the System Game (Stakeholders)

Users: Interact with the system daily, provide input on requirements, and ensure the system meets their needs.
Business Analysts: Understand business needs and requirements. Act as a bridge between stakeholders and the technical team.
System Analysts: Responsible for the technical aspects of system design and implementation, analyze requirements, and ensure the system functions correctly.
Project Managers: Oversee the entire project, ensuring it is completed on time, within budget, and meets requirements.

Required Skills of a Systems Analyst

Analytical Skills: Analyze complex problems, identify solutions, and make data-driven decisions.
Technical Proficiency: Knowledge of programming languages, database management, and software development methodologies.
Communication Skills: Effective verbal and written communication with both technical and non-technical stakeholders.
Interpersonal Skills: Collaboration with diverse teams and building relationships with stakeholders.
Problem-Solving Skills: Identify issues and develop effective solutions.
Project Management: Understanding of project management principles to manage timelines, resources, and deliverables.
Attention to Detail: Meticulousness in documenting requirements and specifications.
Adaptability: Willingness to learn new technologies and adapt to changing business needs.
Business Acumen: Understanding of the business domain and industry to align technical solutions with business goals.
