1. Lecturer: Dr. AJ Bieszczad Chapter 22-1 Process includes: all major process activities resources used, subject to set of constraints (such as schedule) intermediate and final products subprocesses, with hierarchy or links entry and exit criteria for each activity sequence of activities, so timing is clear guiding principles, including goals of each activity constraints for each activity, resource or product

2. Lecturer: Dr. AJ Bieszczad Chapter 22-2 Reasons for modeling a process To form a common understanding To find inconsistencies, redundancies, omissions To find and evaluate appropriate activities for reaching process goal To tailor a general process for the particular situation in which it will be used

3. Lecturer: Dr. AJ Bieszczad Chapter 22-3 Examples of process models Waterfall model Prototyping V-model Operational specification Transformational model Phased development: increments and iterationPhased developmentincrements iteration Spiral model

4. Lecturer: Dr. AJ Bieszczad Chapter 22-4 Dynamic process models Enables enaction of process to see what happens to resources and artifacts as activities occur Simulate alternatives and make changes to improve the process Example: systems dynamics model

5. Lecturer: Dr. AJ Bieszczad Chapter 22-5 Model of Factors Contributing to Productivity
