Design and Production in Software Engineering

Design and Production in Software Engineering

1. Naur

   • Profiles of software designers and producers
     • No Distinction
       • Production
       • Design
         • Properly Belong
           • Performance of the software system
             • Include Decisions

2. Dijkstra

   • If you have your production group
     • it must produce something
       • thing produced has to be
         • Correct
         • Good
   • ability to convince
     • users
     • yourself
     • Product is good
       • Is intertwined
         • Design process

3. Kinslow

   • Design Process is iterative
     • Flowchart
       • Understand the problem
     • Write code
       • Realize that you don´t
     • Go Back
       • do the flowchart
     • Write
       • Some more code
         • Feel is the correct solution

4. Ross

   • Most deadly in software
     • Is the concept
       • specify what you are going to do
         • Then do it
   • Specifications
     • based upon designers ignorance
       • Before they started the job

   • THE NATURE OF SOFTWARE ENGINEERING
     • Perlis
       • A feedback loop is required.
         • Monitor the system
         • Collect system data
         • Make future improvements
     • Fraser
       • Design and execution in stages
         • A usable product is created
         • Products of successive stages
         • Final design requirements
         • Program of usable objects
     • Galler
       • Language designers
         • Implementors should not
         • Implement the desired extensions
     • Selig
       • External specifications
         • Describe the software product
       • The internal design
         • Describe the software product
         • Terms of program structures
       • The internal specifications
         • Implementation process
     • d’Agapeyeff
       • Application programs
         • Middleware
           • Service Routines
             • Control program
               • Compilers
