3. Software Production 0721330 3 What is a process?  A group of homogeneous tasks that are related together in which an outcome can be identified.  People, equipment, input, methods, and environment that work together to produce output.  The set of activities, methods, and practices that are used in the production and evolution of software.  Set of activities, organized in steps, in order to transform users needs into operational software.  Steps, partially ordered, are in interaction and aim to achieve a goal.

4. Software Production 0721330 4 Processes, Activities and Tasks  Activities are carried out by human agents (team) and are supported by tools.  Agent: physical or virtual entity which is able to act in an environment, can communicate directly with other agents, has own resources, and carries out activities related to a role.  Role: Describes a set of responsibilities and obligations assumed by an agent.

8. Discussing the process groups of the IEEE standard Project Management  During project management, the project manager initiates, monitors, and controls the project through the software life cycle. Project management processes

9. Project Management  The Project Initiation Process creates the infrastructure for the project.  During this phase, the task plan, schedule, budget, organization, and project environment are defined.  The project environment includes: project standards, communication infrastructure, meeting and reporting procedure, development methodology, and development tools.  Most of the information generated during this process is documented in the Software Project Management Plan (SPMP).  The Project Initiation Process is complete as soon as a stable environment for the project is established.

10. Project Management  The Project Monitoring and Control Process ensures that the project is executed according to the task plan and budget.  If the project manager observes any deviation from the schedule, he will take corrective action such as reallocating some of the resources, changing procedures, or replanning the schedule. The SPMP is updated to reflect any of these changes.  The Project Monitoring and Control Process is active throughout the lifecycle.

11. Project Management  The Software Quality Management Process ensures that the system under construction meets the required quality standards (which were selected during Project Initiation).  This process is executed by a separate quality management team to avoid conflict in interest (i.e. the goal of the developers is to complete the system on time, and the goal of the quality management team is to ensure that the system is not considered complete until it meets the required quality standard).  The Software Quality Management Process is active throughout most of the lifecycle.

12. Pre-Development  During Pre-Development, management and a client identify an idea or a need.  This can be addressed with a new development effort (greenfileld engineering), or a change to the interface of an existing system (interface engineering), or software replacement of an existing business process (reengineering).  The system Allocation Process establishes the initial system architecture and identifies hardware, software, and operational requirements.  The subsystem decomposition is the foundation of the communication infrastructure among the project members.

13. Pre-Development  The requirements, subsystem decomposition, and communication infrastructure are described in the problem statement, which serves as input for the development process.  The pre-Development processes are depicted in the following table. Pre-Development Processes
