The overall context of process improvement is shown in figure 6. The guidance provided builds directly on ISO It does not presume specific organizational structures, management philosophies, software life cycle models or software development methods.

The concepts and principles are appropriate for the full range of different business needs, application domains and size of organization, so that they may be used by all types of software organizations to guide their improvement activities. The context of process capability determination is shown in figure 7. Before making a contract the acquirer may need to determine the process capability of the prospective contractor, or a supplier may want to ascertain its own process capability before responding to an acquirer's request for proposal.

The technical and other needs for process capability determination are documented in the specified requirements.

The specified requirement is translated into a target capability that represents the required process capability, and process assessment input that will scope the process assessment. The supplier may put forward a proposed process capability as a set of process-by-process capability level ratings to be offered by the organizational unit concerned.

In a straightforward situation, the proposed process capability may be based on a recent self- assessment or by other means. In more complex cases, a supplier may propose a process capability to be achieved in the future based on the supplier's current profile and relevant improvement plans, backed up if possible with improvement records, or a constructed capability including the capability of one or more sub-contractors or partners.

It specifically addresses process capability determination both for use within an organization to determine the risks associated with undertaking a new project sometimes called first party use and for use by an acquirer for assessing external suppliers sometimes called second party or contractual use.

This clause explains the nature of conformance in these two areas. Subclause 5. This is important where an organization wishes to compare its assessment results with those of other similar organizations.

Spice (ISO 15504)

It is especially important in process capability determination in a contractual situation where competing or collaborating suppliers are being compared. The sponsor of the assessment will normally be the party requiring that the assessment conforms to the requirements. When a decision is taken to perform an assessment, the sponsor of the assessment should be responsible for defining the purpose of the assessment.

The sponsor is also responsible for verifying that the assessor has the necessary competence and skills to perform or oversee the assessment. The identity of the competent assessor is part of the assessment input.

Some of the items - particularly assessment scope and constraints - contain a number of elements, and care must be taken to ensure that all of these have been addressed. Documentation of the assessment inputs should be retained in the assessment record, and traceability provided to ensure that it can be verified that the necessary reviews have been performed.

The model s used as the basis for performing the assessment must be compatible with the reference model, and it is required that correspondence is established between the processes in the organizational unit and the reference model, through the use of the assessment model s. Defining the scope in this way ensures that there is a common basis for rating and measurement. Apart from guiding the assessment, the mapping of organizational processes to the compatible model s forms an essential part of the assessment record.

It should be possible, after the assessment has been completed, for any person examining the assessment record to be able to relate the mapping to records of organizational structure, procedures, and standards within the assessed organization.

Indicators of process performance and capability form an objective basis on which judgments of process attribute ratings can be founded. It is this objective basis for judgment that is the foundation of any comparisons of assessment results. The simplest way in which these requirements can be met is for the elements of the compatible model - including the indicators - to be embedded in an appropriate instrument or tool, that permits the recording of observations and evidence throughout the assessment.

This is made possible by implementing the requirements for rating processes and calculating results within the measurement framework, and reporting them in a way that makes the results of the calculation obvious. The results of an assessment formally comprise a set of process attribute ratings for each process in the assessment scope.

The set of process attribute ratings is termed the process profile. Attribute ratings may be used to calculate a capability level rating for the assessed process. Whatever the final format of the process output, it is essential that clear traceability to the processes and process attributes contained in the reference model is provided, to enable the process of calculation to be verified. A clear mechanism for the translation of results has to be provided by the developer of a compatible model, and this mechanism should ensure that such traceability is achieved.

It should be noted that assessment output contains full details of the process context in the assessment record. This record will also include additional information collected as part of the assessment, and required as inputs to the process improvement or process capability determination activities to follow on from assessment.

The reference model identifies critical attributes that a process should have to be considered complete and effective, but without unduly constraining the implementation of the process. Compatible models may be developed by organizations for their own internal use; by acquirers of software systems for use in specific acquisition situations; or by professional organizations defining requirements for specific application domains or use situations.

There must be a clear and unambiguous mapping from the elements in a compatible model to the basic elements of the reference model - the processes and process attributes.

The model must contain a set of indicators of process performance and capability. They are for information purposes only, and should not be taken as implying support for any or all of the approaches described.
