3. WHAT IS SPICE?
ď˘ SPICE â Software Process Improvement & Capability
dEtermination
ď˘ also known as ISO/IEC 15504 is an international standard
for SW process assessments
ď˘ a model that identifies a set of software best practices and
shows how they fit together to create an improvement path
for the software development process
ď˘ Mainly used in Europe and Australia by the automotive
industry
ď˘ Goal
ď˘ To provide assessment results that are repeatable,
objective, comparable
4. AUTOMOTIVE SPICE
ď˘ Automotive SPICE launched in April 2006
ď its usage will increase mainly driven by HIS (Audi, BMW,
Daimler Chrysler, Porsche, Volkswagen), Ford & Volvo, Fiat
ď If OEMâs target levels are not met, then:
ď˘ Suppliers are requested to improve the development processes
ď˘ In case of high risks/low capability levels, the suppliers are
excluded from sourcing
ď (me) structure the way of working
ď (me) identify the main weakness within the development
process and build improvement activities
ď (me) âlinkâ between inputs & outputs
5. THE GOAL OF PROCESS ASSESSMENT
& IMPROVEMENT
Rating
Process Assessment
Improvement
ď The goal of an improvement is to change an organizationâs
processes so that they achieve a higher ability to meet its
businesses goals
ď Assessments deliver the input for any improvement by
detecting strength and weaknesses in the organizations
processes
ď Assessments are also a tool used by customers to ascertain the
ability of their suppliers to meet their needs
6. SPICE STRUCTURE
The measure of the capability is done according to the two-
dimensional evaluations scheme of ISO 15504 (SPICE/
Automotive SPICEÂŽ):
Process Dimension Capability Dimension Two-dimensional
(Automotive SPICEÂŽ) (ISO 15504 'SPICE') Evaluations Scheme
It is possible to identify the
capability of certain processes
Includes processes in groups independent of the others
7. SPICE MODELâS STRUCTURE
ď˘ Process dimension
ď˘ Characterized by set of purpose statements which describe in
measurable terms what has to be achieved in order to attain
the defined purpose of the process
ď˘ Process Capability dimension
ď˘ Characterizes the level of capability that an organization unit
has attained for a particular process or,
ď˘ May be used by the organization as a target to be attained
ď˘ Represent measurable characteristics necessary to manage a
process and improve its capability to perform
11. CAPABILITY LEVEL 1 & 2
Level 1 Level 2
ď˘ The purpose of the process ď˘ The performance of the
process is planned and
is generally achieved checked
ď˘ Work products proof ď˘ The responsibility for
developing the work products
implementation of base is assigned to a person or
practices team
ď˘ No documented process ď˘ Requirements for the work
products are identified,
ď˘ No planning or checks of documented and traced
performance of the process ď˘ Work products are put under
configuration management
ď˘ No quality requirements and quality assurance
for work product are ď˘ No documented or defined
expressed process
12. CAPABILITY LEVEL 3
ď˘ A documented standard process with tailoring guidelines
exists and is used in the project
ď˘ Historical process performance data is gathered
ď˘ Experience from the performance of the process is used for
process improvement
ď˘ Resources and needed infrastructure for the performance
of the process are identified and made available
ď˘ The process is not yet quantitatively understood or
managed
ď˘ Process improvement is reactive
15. MEASURE CAPABILITY LEVELS
ď¨ The fulfillment of a process attribute (PA) is
measured along a scale from 0 â 100% in the
following predefined stages:
ď¤ N (not achieved): 0 â 15%
ďŽ The are no or only very limited indications of PA fulfillment
ď¤ P (partially achieved): 16 â 50%
ďŽ There are some indicators that the PA is implemented to the
measured extent. In some aspects the process remains
unpredictable, though.
ď¤ L (largely achieved): 51 â 85%
ďŽ There is evidence that the PA is implemented to the measured
extend in a useful and systematic way. Process performance
might still show some weaknesses
ď¤ F (fully achieved): 86 â 100%
ďŽ There is evidence for a complete and systematic PA execution to
the measured extent. Process performance does not show any
significant shortcomings due to the analyzed processes
