Requisite Skills for ISAnalytical Skills


Contemplative questions

Contemplative Questions

  • What skills are important for work in IS?

  • Do I have these skills now? Or, do I need to acquire them?

  • Why do I need them?

2.2


List of skills

List of Skills

  • Analytical skills

    • Systems thinking (see separate slides)

    • Organizational knowledge

    • Problem identification

    • Problem analyzing and solving

  • Technical skills

  • Management skills (see separate slides)

  • Interpersonal skills (see separate slides)


Organizational knowledge

Organizational Knowledge

  • Good systems analysts (and employees, in general) understand how organizations work. It is critical to your survival and success in your career.

    • e.g. Who makes the decisions? Who owns the data? Who will resist change? Whom do people follow?

    • Knowledge of specific functions and procedures of organization and department

    • How work officially and unofficially gets done

    • Internal policies, both formal and informal

    • External factors: Competitive and Regulatory Environment

    • Internal factors: Organizational Strategies and Tactics

2.4


Problem solving

Problem Solving

  • A “problem” can be defined in many ways. A generic but useful definition may be a problem is

    • “A discrepancy between an existing and desired state of affairs”

  • Problem identification and problem solving are two different things

    • “A problem well-stated is a problem half-solved.”

    • “A most dangerous and common trap”

    • One of the most important and universal concepts you will learn in this course


Problem identification and solving

Problem Identification and Solving

  • Identify the problem (The Identification)

  • Define the decision criteria (Start the Solving)

  • Weight the decision criteria

  • Develop alternatives

  • Analyze each alternative

  • Select an alternative

  • Implement alternative

  • Evaluate outcome of decision (End the Solving)

Which of these steps is most important?


Some problems encountered with problem solving

Some “Problems” Encountered With Problem Solving

  • Failure to recognize existenceof a problem

  • Failure to define the correct problem

  • Failure to use all available information

  • Failure to recognize and question assumptions

  • Failure to consider a wide range of alternatives

  • Failure to address implementation issues


Root cause analysis

Root Cause Analysis

  • Identify symptoms

  • Trace each symptom back to its causes

  • “The Five Whys”

  • “If there was one thing I wish I had learned when I was younger…”

  • Five whys

Symptoms

Symptoms

ROOT CAUSES


Problem analyzing and solving

Problem Analyzing and Solving

  • Four Phases

    • Intelligence

      • All relevant information is collected

    • Design

      • Alternatives are formulated

    • Choice

      • Best alternative solution is chosen

    • Implementation

      • Solution is put into practice


Technical skills for systems analysis

Technical Skills for Systems Analysis

  • Constant re-education is necessary as technology changes rapidly

  • Activities to keep skills up-to-date
