SPICE Assessment Types

• Self-Assessment
• Assisted Self-Assessment
• Self-Assessment with External Verification
• Independent Assessment

Ratings

• Each Process instance is rated
• Base Practice adequacy scale
• N, Not Adequate The base practice is either not
  implemented or does not to any degree contribute
  to satisfying the process purpose
• P, Partially Adequate The implemented base
  practice does little to contribute to satisfying
  the process purpose
• L, Largely Adequate The implemented base practice
  largely contributes to satisfying the process
  purpose
• F, Fully Adequate The implemented base practice
  fully contributes to satisfying the process
  purpose
• Base Practice existence scale (N, Y)
• Generic Practice adequacy scale (N, P, L, F)

• Performed Informally
• Planned and Tracked
• Well-Defined
• Quantitatively Controlled
• Continuously Improving

Process Improvement Roadmap

Continuously Improving

• Capability Levels taken from ISO SPICE model v1.0
• Capability levels provide logical and structured
  methodology for improving how work is performed

Quantitative strategic goals
Processes improved

Goals of BOOTSTRAP

• Valuation of the capability level on SPU Software
  Producing Unit) and project level for
• process categories
• each process
• Comparison of capability levels between the
  projects and the SPU
• Benchmarking the capability level against
  european mean value
• overall
• in the defined business segment
• Identifying the main strength and weaknesses of
  the company
• Support to define adequate business goals
• Define and implement an improvement plan

ISO 9000 Series

• Actually a series of specifications that allow
  companies to be certified
• Doesnt focus on improvementjust current state
• Addresses minimum criteria for a quality system
• Strongly paper-trail oriented
• Checklist assessment
• Genericnot software specific
• Principle Every important process should be
  documented

21
Example from ISO 90012000

• 4 Systemic Requirements
• 4.1 Establish your quality system
• Develop your quality management system
• Identify the processes that make up your quality
  system.
• Describe your quality management processes. 
• Implement your quality management system
• Use quality system processes.
• Manage process performance.
• Improve your quality management system
• Monitor process performance.
• Improve process performance

An ISO 9001 compliant organization should be at
or near CMM 2 with significant progress towards
level 3.
CMM has no delivery and product handling process.
24
Conclusions

• CMM-I seems to have pretty much won the wars,
  although the other methods are more productized.
• Other methods focus on specific tailored
  processes rather than everything
• ISO 9000 is a separate issue in certification
  rather than assessment.
