Soliciting & Setting Up Projects
   Instructor solicits projects from
       Contacts with CSIS faculty interested in creating
        research-related systems, sometimes in
        collaboration with other universities or local
        research companies
       E-mail to various university departments

Forming Teams and
Assigning Projects
    Last year 2001-2

          (usually based solely on friendship)
         Each teams submitted 5 project preferences
         Instructor assigned teams to projects
          (tedious, far from optimal, can be perceived as unfair)
    This year 2002-3
         Project group assignment system automatically
          forms teams and assigns projects
          (automatic, close to optimal, unbiased and objective)
    Managing Systems
    Development Process
   Requirements analysis
       Through use cases and use scenarios
   Analysis and design – tools/methodologies
       Depend highly on type of system being developed –
        e.g., database requires database methodologies
   Construction of the system
   Test system to ensure
       It meets customer’s requirements
       All functions operate correctly
