Study Notes

What is a Systems Analyst?

Responsible for implementing, maintaining, and supporting IT and information systems to meet organizational business needs.
Average base pay for a Systems Analyst is $119,000.
Example systems analysis activities might include updating computer code, fixing faulty systems, or analyzing routines to prevent mistakes.

Computer Application (App)

This is a software program that executes on a computing device to perform a specific set of functions.
These have a modest scope.

Information System

This is a collection of components that gather, process, store, and output information to complete business tasks.
Examples include airline reservation systems, CRM systems, hospital management systems, and ERP systems.
These are broader in scope than computer applications.
Include databases, related manual processes, and multiple applications.
Analogy: Computer applications are like sandwiches while information systems are the restaurant.

Systems Analysis

This involves activities to understand and specify the goals of an information system.

Systems Design

This focuses on defining and describing the system in detail to meet the requirements identified during the analysis phase.

Systems Analysis and Systems Design Examples

Inventory Management System Example:
- Systems Analysis: Understanding the current inventory management process, pain points, and requirements to improve the system.
- Systems Design: Defining the technical architecture, designing system components, creating database structures, and designing user interfaces for the system.

Software Development Process

This is a structured approach to building and launching an information system.
It has seven phases, each building upon the previous one:
- Understand the need: Identify the business need.
- Capture the vision: Define the goals of the system.
- Define a solution: Outline the proposed solution.
- Communicate the vision and solution: Present the plan effectively.
- Build the solution: Develop the system components.
- Confirm that the solution meets the need: Test and validate the system.
- Launch the solution system: Deploy and implement the system.

System Development Life Cycle (SDLC)

Also known as the Waterfall Model.
Consists of six core processes that guide the development, launch, and maintenance of an information system:
- Identify the problem or need and obtain approval: Define the problem and get permission to start the project.
- Plan and monitor the project: Define project components, establish timelines, and assign responsibilities.
- Discover and understand the details of the problem or need: Gather information through fact-finding, interviews, and use case development.
- Design the system components that solve the problem: Define the database, design components, and establish the architecture.
- Build, test, and integrate system components: Program and build components, conduct testing, and integrate the system.
- Complete system tests and then deploy the solution: Perform final system tests and deploy the system for use.

Project

A planned undertaking with a defined start and end, aiming to produce a specific outcome.
Used to develop information systems.
Requires knowledge of systems analysis and systems design tools and techniques.

System Development Process

The specific method used to develop a particular information system, often referred to as a methodology.
Many processes or methodologies use Agile and Iterative development.

Agile Development

Emphasizes flexibility to adapt to new requirements during development.
Values quick response and adaptability to changes.

Iterative Development

Involves building the system gradually in multiple iterations.
Focuses on refining and adding features in small increments.

Core Process 1: Identify the Problem and Obtain Approval

Activities:
- Define and document the problem and system objectives.
- Conduct a preliminary investigation.
- Develop a System Vision Document.
- Secure approval from key stakeholders, including executive management.
- Reach a decision, finalizing the plan and budget.

Core Process 2: Plan the Project

Activities:
- Identify major project components (functional areas).
- Define iterations and assign functions to each.
- Determine team members and their responsibilities.

Core Process 3: Discover and Understand Details

Activities:
- Conduct preliminary fact-finding, such as interviews with staff to understand how they manage inventory.
- Develop use cases, outlining how users interact with the system, using an example like "updating inventory."
- Develop a class diagram to visualize how the system organizes data, such as product information, suppliers, and orders.

Core Process 4: Design System Components

Activities:
- Design the database, including tables for products, suppliers, and stock levels.
- Design the high-level structure, such as deciding if the system will be a web application.
- Define the architectural configuration, determining how the user interface and back-end interact.
- Design class diagrams to illustrate relationships between entities, like products, suppliers, and orders.

Core Process 5: Build, Test, and Integrate

Activities:
- Continue programming to develop the system.
- Build the system component by component, implementing each use case, like "adding new products."
