Systems Engineering Reflects the following Axioms

• Fixing a problem after delivery costs 100 times
  more than fixing it during design
• About 15 of software development effort is
  devoted to programming
• Walkthroughs catch 60 of the errors

Staffing Considerations

• Dont proceed if you cant staff the project
• Client inexperience reduces probability of
  success by 30
• Supplementary staff available
• Consultants
• Non-profits
• Universities
• Reference Capers

Course Learning Objectives

• List the reasons that systems engineering is
  important for ITS
• Name the steps in the systems engineering process
• Differentiate between cross-cutting practices and
  the steps in the process
