You have reviewed the Module Three resources and spent some time learning about process models. You will spend some time discussing these concepts with your classmates in order to gain a deeper understanding of the topics and how they apply to system analysis and design.

In your initial post, be sure to address each of the following:

• Why are process models typically used in system design?
• Which of the guidelines for drawing DFDs (completeness, consistency, timing considerations, iteration) do you think is the most important for creating a good process model? Why?
• Imagine that somebody creates a process model illustrating "Student Completion of CS 255." One process might be for the student to "Complete Project One". How would you decompose this process?
• 
  
• Note: You are not required to create a DFD to model this process. Instead, simply describe it in words.
