WEEK 1: INTRODUCTION TO INFORMATION SYSTEMS AND DEVELOPMENT AND MANAGEMENT

Information System

A set of components that work together to collect, process, store, and share information.

Information System

This usually to guides decision-making to improve efficiency and profitability.

1. Hardware

2. Software

3. Data sources

4. Telecommunications

5. Process

6. Human Expertise

What are the 6 components of Information System?

Humans

possess a unique ability to empathize, interpret emotions, and cater to the user experience.

Empathetic understanding

• This —— is vital for designing IT solutions that resonate with the needs, emotions, and expectations of end-users, fostering a more meaningful and user-centric technological landscape.

Information Systems Analysis and Design

This is the process that teams follow to create or improve an information system.

Information Systems Analysis and Design

It involves studying the organization’s needs, identifying problems, and designing solutions.

Application Software

One of the important result of information systems analysis and design.

Application Software

Designed to support a specific organizational function or process.

System Analyst

They’re the bridge between the business side and the technical side.

System Development Methodology

a standard process followed in an organization to conduct all the steps necessary to analyze, design, implement, and maintain information systems.

Systems Development Lifecycle (SDLC)

a common methodology for systems development in many organizations; it features several phases that mark the progress of the systems analysis and design effort.

1. Planning

2. Analysis

3. Design

4. Implementation

5. Maintenance

What are the 5 Phases of SDLC

Planning

• Priorities for systems and projects; an architecture for data, networks, and selection hardware, and information systems management are the result of associated systems detailed steps, or work plan.

• For project specification of system scope and planning and high-level system requirements or features assignment of team members and other resources system justification or business case.

Analysis

• Description of current system and where problems or opportunities exist, with a general recommendation on how to fix, enhance, or replace cur rent system.

• Explanation of alternative systems and justification for chosen alternative.

Design

• Functional, detailed specifications of all system (data, processes, inputs, and outputs).

• Technical, detailed specifications of all system elements (programs, files, network, system software, etc.). Acquisition plan for new technology.

Implementation

Code, documentation, training procedures, and support capabilities.

Maintenance

New versions or releases of software with associated updates to documentation, training, and support.

Software Engineering

encompasses process, methods, and tools that enable complex computer-based systems to be built in a timely manner with quality.

1. Communication

2. Planning

3. Modeling

4. Construction

5. Deployment

What are the Software Process (5 Framework Activities)?

(this is in ASC order; smallest to biggest)

1. Tools

2. Methods

3. Process

4. A quality Focus

What are the Software Engineering Layers?

1. Understand the problem

2. Plan a solution

3. Carry out the plan

4. Examine the result for accuracy

What are the Software Engineering Practices?

Project Management

is the practice of planning, organizing, and overseeing the execution of a project from start to finish.

Project Management

involves defining project goals, identifying tasks and resources required to achieve them, setting timelines, and monitoring progress to ensure the project is completed on time, within budget, and to stakeholders’ satisfaction.

Project Management

involves various processes and methodologies, including risk management, stakeholder management, and communication management. It is essential for ensuring the success of projects in various fields, including software development, construction, marketing, and many others.
