1. The analyst as a business problem solver1. The analyst as a business problem solver

ISs are crucial to modern business organizations

The key to successful system development is systems analysis and design

Def.Def. Systems Analysis (SA) is the process of understanding and specifying in detail what the information system should do.

Systems Design (SD) is the process of specifying in detail how the many components of the information system should be physically implemented.

Systems Analyst (SAn) is a business professional who uses analysis and design techniques to solve business problems using information

technology and who develops IS.

The analyst as a business problem The analyst as a business problem solver (cont’d)solver (cont’d)

Any IS is to solve problems for an organization

Systems analyst is a problem solver rather than a technical programmer (see Figure 1-12)

A great variety of special skills is required:

Technical Knowledge and Skills Business Knowledge and Skills People Knowledge and Skills Integrity and Ethics

Analyst’s Approach to Problem Analyst’s Approach to Problem SolvingSolving

Verify benefits of solving problem outweigh the costs

Research and understand the problem

Define the requirements for solving the problem

Develop a set of possible solutions (alternatives)

Define the details of the chosen solution

Monitor to ensure desired results

Decide which solution is best and recommend

Implement the solution

Technical Knowledge and Skills (2 Technical Knowledge and Skills (2 of 2)of 2)

Analyst uses tools

Software productivity packages

Integrated development environments (IDEs) for programming languages

Visual modeling tools and code generation tools

Analyst understands SDLC techniques

Project planning, cost/benefit, interviewing

Systems requirements modeling including

Design, database design, network configuration

Page 8: 1 Lecture 1.b Introduction to Systems Analysis. Basic Concepts [Prof. Peter Khaiter] ITEC 3010 “Systems Analysis and Design, I”

Business Knowledge and SkillsBusiness Knowledge and Skills

Analyst must understand

Business functions performed by organization

Strategies, plans, traditions, and values of the organization

Organizational structure

Organization management techniques

Functional work processes

Systems analysts typically study business administration/management in college with a major in CIS or MIS

Page 9: 1 Lecture 1.b Introduction to Systems Analysis. Basic Concepts [Prof. Peter Khaiter] ITEC 3010 “Systems Analysis and Design, I”

People Knowledge and SkillsPeople Knowledge and Skills

Primarily a systems analyst must be an effective communicator

A systems analyst must be able to perform various roles such as negotiator, teacher, mentor, collaborator, and manager

Page 10: 1 Lecture 1.b Introduction to Systems Analysis. Basic Concepts [Prof. Peter Khaiter] ITEC 3010 “Systems Analysis and Design, I”

10

Integrity and EthicsIntegrity and Ethics

Analyst has access to confidential information, such as salary, an organization’s planned projects, security systems, and so on.

Must keep information private

Any impropriety can ruin an analyst’s career

An analyst plans the security in systems to protect confidential information
