    • 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

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

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
