PREAMBLE

    In January 1993 a program of work was approved by ISO/IEC JTC1 for the development of an

    international standard for software process assessment. In June 1993 the SPICE Project

    Organisation was established with a mandate from JTC1/SC7 to:

     assist the standardisation project in its preparatory stage by developing initial working drafts; undertake user trials in order to gain early experience data which will form the basis for

    revision of the Technical Report prior to publication as a full International Standard;

     create market awareness and take-up of the evolving standard. The SPICE Project Organisation completed its task of producing the set of working drafts in June 1995. The SPICE user trials commenced in January 1995. The working drafts have now been

    handed over to JTC1/SC7 for the normal process of standards development, commencing in July

    1995.

    So far as can be determined, intellectual property rights for these documents reside with the individuals and organisations that contributed to their development. In agreeing to take part in the Project, participants agreed to abide by decisions of the Management Board in relation to the conduct of the Project. It is in accordance with this understanding that the Management Board has now agreed to release the baseline set of documents. This introductory statement sets out the terms and conditions under which this release is permitted.

Foreword

In June 1991, the fourth plenary meeting of ISO/IEC JTC1/SC7 approved a study period (resolution

    144) to investigate the needs and requirements for a standard for software process assessment.

    The results, which are documented in a Study Report (JTC1/SC7 N944R, 11 June 1992), came to the

    following major conclusions:

     there is international consensus on the needs and requirements for a standard for process

    assessment;

     there is international consensus on the need for a rapid route to development and trialing to

    provide usable output in an acceptable timescale and to ensure the standard fully meets the

    needs of its users;

     there is international commitment to resource the project with an international project team

    staffed by full time resource, with development being co-ordinated through four technical

    development centres in Europe, N America (2) and Asia Pacific;

     the standard should initially be published as a Technical Report Type 2 to enable the

    developing standard to stabilise during the period of the user trials, prior to its issuing as a full

    International Standard.

    The new work item was approved in January 1993 by JTC1. In June 1993 the SPICE Project

    Organisation was established with a mandate from JTC1/SC7 to:

     assist the standardisation project in its preparatory stage to develop initial working drafts;

     undertake user trials in order to gain early experience data which will form the basis for

    revision of the published Technical Report prior to review as a full International Standard;

     create market awareness and take-up of the evolving standard.

    The SPICE Project Organisation completed its task of producing the set of working drafts in June

    1995. These working drafts have formed the basis for this Technical Report Type 2. The period of

    SPICE user trials commenced in January 1995 and is synchronised in phases to allow feedback to

    the stages of the technical work.

    ISO/IEC Directives state that a Technical Report Type 2 may be used to publish a prospective

    standard for provisional application so that information and experience of its practical use may be

    gathered.

    This Technical Report Type 2 consists of the following parts, under the general title Software Process

    Assessment:

     Part 1 : Concepts and introductory guide Part 2 : A model for process management Part 3 : Rating processes

     Part 4 : Guide to conducting assessment Part 5 : Construction, selection and use of assessment instruments and tools

     Part 6 : Qualification and training of assessors Part 7 : Guide for use in process improvement Part 8 : Guide for use in determining supplier process capability ISO/IEC Software Process Assessment Part 8: Guide for use in determining supplier process capability Working Draft V1.00 Page 1 Part 9 : Vocabulary

    This part of the standard (Part 8) is for guidance only.

1. Scope

    This part of the International Standard provides guidance on how to utilize process assessment for the purposes of process capability determination

    A process capability determination (PCD) is a systematic assessment and analysis of selected software processes within an organization, carried out with the aim of identifying the strengths, weaknesses and risks associated with deploying the processes to meet a particular specified requirement.

    Process capability determination is applicable in a variety of situations; the specified requirement may involve a new or an existing task, a contract or an internal undertaking, a product or a service, or any other requirement which is to be met by deploying an organization's software processes. This guidance is intended to be applicable across all software application domains, over all software organizational structures, within any software customer-supplier relationship, and to any organization wishing to determine the process capability of its own software processes.

    This guide is primarily aimed at:

     the sponsor who initiates the process capability determination; the organization whose process capability is to be determined; the assessment team;

     tool and method developers.
