Ch2 - Process Models
- A process pattern
- describes a process-related problem that is encountered during software engineering work
- identifies the environment in which the problem has been encountered
- suggests one or more proven solutions to the problem.
- A process pattern provides you with a template - a consistent method for describing problem solutions within the context of the software process.
- Patterns can be defined at any level of abstraction. In some cases, a pattern might be used to describe a problem (and solution) associated with a complete process model.
- patterns can be used to describe a problem (and solution) associated with a framework activity (e.g., planning) or an action within a framework activity (e.g., project estimating).
- Ambler [Amb98] has proposed a template for describing a process pattern:
- Pattern Name
- Forces - The environment in which the pattern is encountered and the issues that make the problem visible and may affect its solution.
- Stage pattern - defines a problem associated with a framework activity for the process.
- Task pattern - defines a problem associated with a software engineering action or work task and relevant to successful software engineering practice.
- Phase pattern - define the sequence of framework activities that occurs within the process, even when the overall flow of activities is iterative in nature.
- Initial context - Describes the conditions under which the pattern applies.
- What organizational or team-related activities have already occurred?
- What is the entry state for the process?
- What software engineering information or project information already exists?
- Problem - The specific problem to be solved by the pattern
- Solution - Describes how to implement the pattern successfully
- Resulting Context - Describes the conditions that will result once the pattern has been successfully implemented.
- Related Patterns - Provide a list of all process patterns that are directly related to this one.
- Known Uses and Examples - Indicate the specific instances in which the pattern is applicable.
Prescriptive Process Models
The Waterfall Model
Incremental Process Models
Evolutionary Process Models
Evolutionary models are iterative.
They are characterized in a manner that enables you to develop increasingly more complete versions of the software.
The Spiral Model
The Unified Process (UP)
- UP Phases
- UP Work Products
- Personal Software Process (PSP)
- Team Software Process (TSP)
