8.1 Organization Process Focus
  • Purpose To establish the organizational
    responsibility for SW process activities that
    improve the organizations overall software
    process capability
  • Involves developing and maintaining an
    understanding of the organizations and projects
    SW processes and coordinating the activities to
    assess, develop, maintain, and improve these
    processes
  • The organization is responsible for providing
    long term commitments and resources to coordinate
    the development and maintenance of the SW
    process across the current and future projects
    via a group
  • (I.e. SWE group, Software related groups, SWE
    process groups, System Engineering groups, System
    Testing groups, SWQA groups,SW Configuration
    management groups, and Training groups)

8
Organization Process Focus
Goals 1. SW activities coordinated across
organization 2. SWOT of SW processes used to
identify and related to a process standard 3.
Organizational level process development and
improvement activities are planned
9
Organization Process Focus
Commitment to Perform 1. Organization follows
written policy for coordinating SW process
development and improvement activities across the
organization 2. Senior Management Sponsors the
Organizations activities for SW development and
improvement 3. Senior Management Oversees the
organizations activities for SW process
development and improvement
10
Organization Process Focus
Ability to Perform 1. A group that is
responsible for the Organizations SW process
activities exists 2. Adequate resources and
funding are provided for the Organizations
software process activities 3. Members of the
group responsible for the organizations SW
process activities receive required training to
perform these activities 4. Members of the SWEG
and other SW-related groups receive orientation
on the organizations SW process activities and
their roles in those activities
11
Organization Process Focus
Activities Performed 1. The SW process is
accessed periodically, and action plans are
developed to address the assessment findings 2.
The organization develops and maintains a plan
for its SW process development and improvement
activities 3. The Organizations and projects
activities for developing and improving their
software processes are coordinated at the
organizational level 4. The use of the
organizations SW process database is coordinated
at the organizational level
12
Organization Process Focus
Activities Performed Cont.- 5. New processes,
methods, and tools in limited use in the
organization are monitored, evaluated, and where
appropriate, transferred to other parts of the
organization 6. Training for the Organizations
and projects SW processes is coordinated across
the organization. 7. The groups involved in
implementing the SW processes are informed of the
organizations and projects activities for SW
process development and improvement
13
Organization Process Focus
Measurement and Analysis 1. Measurements are
made and used to determine the status of the
Organizations process development and
improvement activities (I.e Work completed,
effort expended, and funds expended in the
Organizations activities for process assessment,
development, and improvement compared to the
planned activities Also the results of the
assessments relative to previous assessments)
14
Organization Process Focus
Verifying Implementation 1. The activities for
SW process development and improvement are
reviewed with senior management on a periodic
basis a. Progress and status of activities to
develop and improve SW processes reviewed against
the plan b. Unresolved conflicts resolve c.
Action items are assigned, reviewed and tracked
to closure d. Summary Report for each review
distributed to appropriate groups
15
8.2 Organization Process Definition

    understanding of the organizations standard SW
    process, along with related process assets
  • (I.e. Descriptions of SW life cycles, process
    tailoring guidelines, and criteria, the
    organizations SW process database, and a library
    of software process- related documentation )
