requirements for a spice assessment
REQUIREMENTS FOR ASPiCE ASSESSMENT
  • A set of defined input information has to
  • be prepared before the assessment.
  • Assessment has to be against a model that is
  • compatible with the SPICE reference model.
  • The model has to provide indicators to guide the
  • assessor in rating the processes of the reference
  • model.
  • The assessment results, the process ratings, have to be justified objective evidence of the existence
  • of the indicators in the assessment model.

  • Purpose statement: “The purpose of the Develop Software Requirements process is to establish the requirements of the software component of the system.”
  • A list of outcomes achieved: “The requirements allocated to software components of the system and their interfaces will be defined to match the customer’s stated and implied needs; …”

spice compatible assessment model
SPiCE . . . Compatible Assessment Model
  • Model purpose- for process assessment.
  • Model scope - a subset of the process dimension and a “continuous” subset of the levels of the capability dimension.
  • Mapping - elements of the model are mapped to the elements of the SPICE reference model.
  • Translation - the mechanism for converting the data collected against the assessment model into the SPICE rating scheme.

spice process attributes
SPiCE . . . Process Attributes

The capability model is based on nine process attributes (one at level 1 and two at levels 2 to 5)

Level 5 5.1 Process Change 5.2 Continuous ImprovementLevel 4 4.1 Process Measurement 4.2 Process ControlLevel 3 3.1 Process Definition 3.2 Process ResourceLevel 2 2.1 Performance Management 2.2 Work Product ManagementLevel 1 1.1 Process Performance

spice process indicators
SPiCE . . . Process Indicators
  • Indicators - are used to support the assessor’s judgement in rating process attributes. Generally there are process performance indicators and process management indicators.
  • Objective evidence - based on the indicators, must be documented to justify assessment ratings
  • Example indicators - work products, practices, records, reports.

spice assessment process
SPiCE . . . Assessment Process
  • Each process in the assessment scope is assessed by examining one or moreprocess instances(e.g. each time the code for a new software product is written, a process instance of an implemented software design is created.)
  • The assessment process is based on the set of process instances selected that satisfy the purpose and scope of the assessment.
