  1. 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.

  3. SPiCE . . . Process Descriptors See page 25 - example for ENG.2 • 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 Requirements - slide#3

  4. SPiCE . . . Process Descriptors • Notes providing further information: “This process is identical in scope to Activity 4 of the Development Process, one of the Primary Life Cycle Processes in ISO 12207.” SPiCE Requirements - slide#4

  6. 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.

  8. 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 Requirements - slide#8

  9. 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.

  11. 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.
