Study Notes
The Systems Analyst
- Central figure in Information Systems (IS) development, pivotal in the Systems Development Life Cycle (SDLC).
- Analyzes business situations to identify improvement opportunities and designs solutions using technology.
- Acts as a change agent, facilitating organizational improvement and system use.
Skills of Systems Analysts
- Technical: Knowledge of technical environments and solutions.
- Business: Understanding of IT applications in business contexts.
- Analytical: Strong problem-solving abilities.
- Interpersonal: Effective communication skills are essential.
- Management: Capable of managing people, pressure, and risks.
- Ethical: Must engage fairly and honestly with all stakeholders.
Roles within Systems Analysis
- Systems Analyst: Focus on IS issues.
- Business Analyst: Concentrates on business concerns.
- Infrastructure Analyst: Deals with technical aspects.
- Change Management Analyst: Manages human and organizational issues.
- Project Manager: Ensures project completion on time and budget.
Systems Development Life Cycle (SDLC)
- Structured process comprised of four main phases: Planning, Analysis, Design, and Implementation.
- Each phase involves specific steps and deliverables that guide project success.
Planning Phase
- Establishes the need for a new system and outlines the approach for project development.
- Project Initiation: Identifies business value (cost reduction, revenue increase).
- Project Management: Develops work plans, accountability, and control mechanisms for the project.
Analysis Phase
- Defines user roles, system functionality, and operational details.
- Involves examining current systems, spotting improvement areas, and conceptualizing a new system.
-
Steps include:
- Analysis Strategy: Guides team in reviewing current systems.
- Requirements Gathering: Develops a concept for new systems.
- System Proposal: Presented to decision-makers for project approval.
Design Phase
- Outlines system operation specifics, including hardware, software, and user interface.
-
Steps include:
- Design Strategy: Determines internal or external development.
- Architecture Design: Specifies needed technology infrastructure.
- Database and File Specifications: Clarifies data storage needs.
- Program Design: Lays out programming needs.
Implementation Phase
- Involves developing or installing the system and ensuring it meets designs.
-
Steps include:
- System Construction: Building and testing the system.
- Installation: Transitioning from old to new systems.
- Support Plan: Includes reviews and change management processes.
Project Identification and Initiation
- Initiated when a business need for a new system is recognized.
- May stem from competitive IT opportunities and advancing technologies (e.g., cloud computing).
Business Process Management (BPM)
- A methodology for continuously improving business processes, leading to new IS projects.
-
BPM Tasks:
- Define, improve, and streamline processes.
- Innovate through Business Process Automation (BPA), Improvement (BPI), or Reengineering (BPR).
Project Sponsor
- Individual or group invested in system success who guides project alignment with business objectives.
- Supports project decisions and facilitates communication among stakeholders.
System Request
- Formal document outlining the need for the system and expected benefits.
- Key elements include business need, requirements, value, and relevant issues.
Feasibility Analysis
- Assesses whether to proceed with a project, highlighting associated risks.
- Evaluates three feasibility areas: Technical, Economic, and Organizational.
Technical Feasibility
- Analyzes system design, development, and installation feasibility, focusing on technical risks.
Economic Feasibility
- Cost-benefit analysis determining whether the system should be built by evaluating financial factors.
Organizational Feasibility
- Assesses user acceptance and integration into existing processes, ensuring alignment with business goals.
Summary
- The Systems Analyst is crucial in IS development through the SDLC, encompassing Planning, Analysis, Design, and Implementation.
- Effective project identification leverages technology for addressing business needs.
- Comprehensive feasibility analysis is vital for managing project risks and enhancing success potential.
