Focusing on Organizational Focusing on Organizational Process ImprovementProcess Improvement
At Level 3, the entire organization becomes focusedon process improvement. It’s an important step up the maturity scale. At this point your teams have developed a set of proven processes and practicesthat have been shown to work over time and across
a wide variety of projects. The challenge now is to gather these into a single program and then to implement it across the organization, with the idea of measurement and improvement still in mind. -- Alan Waklin, Micronetix Corporation

• Understanding existing processes• Introducing process changes to achieve
organisational objectives which are usually focused on quality improvement, cost reduction and schedule acceleration
• Most process improvement work so far has focused on defect reduction. This reflects the increasing attention paid by industry to quality
• However, other process attributes can be the focus of improvement

• Process analysis– Model and analyse (quantitatively if possible)
existing processes• Improvement identification
– Identify quality, cost or schedule bottlenecks• Process change introduction
– Modify the process to remove identified bottlenecks
• Process change training– Train staff involved in new process proposals
• Change tuning– Evolve and improve process improvements

• Creating the SPI plan is a core effort for Level 3 shops
• CMM is not really a software process improvement program. It is a framework on which you can build your own SPI program.
• CMM gives you the infrastructure and direction to instantiate SPI activities.

Organization Process DefinitionOrganization Process Definition
The entry for Level 3 is a degree of maturity markedby an already present focus on process improvement. The move to Level 3 – the organization’s adoption of A common set of software development processes and practices – is almost always accompanied by aDepth of experience that provides a benchmark for What works well. At level 3, that knowledge is Formally defined. -- Booch Kasadian, Process Development Enterprises

• The documented processes and practices that you elected to institutionalize across the organization
• The descriptions of the software development life cycles you have elected to allow for use on your project.
• The set of tailoring guidelines that helps your people fine-tune the SSPS to the unique needs of a specific project.
• The establishment of a common measurement database used as a repository for all project-level process and practice measurements.
• A centralized process library that is used to manage and version control the contents of the SSPS.

Creating Level 3 StructuresCreating Level 3 Structures
The Structure that put into place at Level 3 are there,ultimately, to help you communicate. There is organizational need to share a common body of knowledge with the workforce. There are also specific communication needs within each project –sharing information on process, status, and the riskseach group needs to be aware of. -- Dan Payne, Senior Analyst, Lockheed-Martin Corp

Creating Level 3 ProcessesCreating Level 3 Processes
Effective process management at Level 3 requires the extension of what you have built at Level 2. At Level 2 you set the pillars in place for process improvement. At Level 3 you strengthen them, and the foundation for process improvement settles intoplace.
-- Ransom Day, Public Health Software Systems
Level 3 Mostly Just Extends Level Level 3 Mostly Just Extends Level 2 on Processes2 on Processes
For CMM Level 2, you’ll set up processes for RM, SPP, SQA, CM,
and vendor management. Each of these areas can be seen as existing
in may ways apart from each other. Each addresses a specific
functional area along the development chain. But at Level 3 things
change. The CMM introduces only one more independent KPA,
Training Program. The others-Organization Process Focus,
Organization Process Definition, Integrated Software Management,
Software Product Engineering, Intergroup Coordination, and Peer
Review – all serve to expand the Level 2 processes, to deepen their
reach within the organization, to crystallize tracking elements down
to finer detail.

• The SPE KPA of the CMM is a different kind of KPA. From it, the CMM begins to address direct intervention into the rote technical activities involved in software development.
• The idea of a software product engineering KPA lies pretty much in its name: improved technical performance through the administration of process measures.

• The ISM KPA is in place to help coordinate the use of the organization’s SSPS across the projects within the organization.
• The ISM KPA also guides how to tailor the SSPS to DSPS which is used to shape and control various elements of project progress and activity results.
Guidelines for Tailoring the SSPSGuidelines for Tailoring the SSPS
• Study and then define the tailoring steps• Document the guidelines for all to use• Establish the procedures to waive certain
SSPS steps• Peer review the guidelines for approval• Configuration manage the resulting guidelines

Intergroup Coordination ProcessesIntergroup Coordination Processes
• Software development can involve many different groups.• Software development usually fares poorly in an isolationis
t environment.• Communication is vital for any project, not just within team
s but between teams.
• The effective and coordinated communication is so important to quality software development.
• In fact, we might say that the CMM is all about coordination. The plans, processes, and practices employed to create a product are there as a way to coordinate activity in a predicable and trackable manner.
Is IC Different from Regular Project Is IC Different from Regular Project Status Meeting?Status Meeting?
No• In the sense that any exch
ange between groups can be seen as a status meeting of sorts, and the format that you’ll use for the exchanges will be probably be for all practical matters the same as for regular status meetings.
Yes• In the sense that these exc
hanges, the IC “events” will be individually planned in advance. They will be anticipated in the project plan and recognized as perhaps “formal” status meetings where specific items, not just project progress in general, need to be addressed.

Creating Level 3 Training ProgramCreating Level 3 Training Program
Training is an important long-term success factor in organizations. Personnel management studies point out an interesting correlation – companies that invest in training show a lower level of turnover than companies that don’t. Training not only brings needed skills and knowledge to the workforce, but it in many other ways reinforces the workforce, imparting both asense of individual growth and a sense of common mission. -- Makie May, Quality Assurance Consultant
