• A process is a sequence of steps.
  

• A method is a notation and an approach that provides a technique for accomplishing several steps in a process (For example: an analysis method might use the UML notation and be used for the domain and application analysis models).
  

• A process script is a description of how to carry out the tasks necessary to complete a step in a process. It is a checklist.
  

• Script for writing a JOOP column
  

Personal Software Process

• A technique for quantifying the work done by an individual software engineer
  

• Set of metrics
  

• Set of analysis formulae
  

• Implemented by a set of forms and scripts
  

Quality Work

• Requires discipline
  

• Develop specific skills
  

• A defect that may appear only once in a billion executions could occur several times a day given today's processing speeds
  

• 
  

Process Improvement

• Use measures that quantify important aspects of the process
  

  • Metric: number of corrections made by the editor at JOOP
    

  • Goal: zero grammatical corrections by the editor
    

• Collect data on the process
  

• Analyze the data to pinpoint problems
  

• Hypothesize causes for problem
  

• Develop a Process Improvement Plan (PIP)
  

• Modify the appropriate process script
  

• Continue to collect data to determine if the modification is an improvement
  

First Step

• Write a first program - TBA
  

• Use Time Recording Log to track time spent on each task
  

• Follow the process!!
  

  • Analysis - construction a problem model
    

  • Design - construct a solution model
    

  • Implement - write the code for the solution model
    

  • Compile - use compiler
    

  • Test - yes, really test - try lots of different values
    

• Use the defect tracking log to record program errors
  

872 Assignment

• Write a program that calculates the standard deviation of a set of numeric data. The data should be held in a linked list.
  

• Use any language you wish.
  

• Follow the basic process
  

• Record time for each step
  

• Submit a working program
  

• Submit a completed time recording log
  

• Submit a completed defect tracking log
  

• Submission:
  

  • email file names and addresses to instructor
