What is the ISO/IEC 15504 Standard?
ISO/IEC 15504, commonly known as SPICE (Software Process Improvement and Capability Determination), means ‘Software Process Improvement and Capability Determination’ in Turkish. It is an international quality management standard created to improve the quality of software development processes.
This standard has been expanded from its initial versions, which covered software development processes, to include all relevant processes related to software organisations.
These processes have expanded to cover six areas: organisational, management, engineering, acquisition and supply, support, and operations. In a major revision of the draft standard in 2004, the process reference model was removed and is now linked to ISO/IEC 12207 (Software Life Cycle Processes).
Purpose of the ISO/IEC 15504 Standard
The primary purpose of the SPICE standard is to improve the quality of software development processes, ensure the efficiency and effectiveness of processes, and create a continuous improvement cycle to gain a competitive advantage internationally. This standard aims to reduce the failure rate of software projects and ensure quality control.
The ISO/IEC 15504 standard is used by a wide range of users, including software development companies, healthcare information system manufacturers, the automotive industry, public and private sector projects, certification and audit organisations, training and consulting firms, and the defence industry.
Key Components and Competence Levels of the ISO/IEC 15504 Standard
The ISO/IEC 15504 standard has two main components:
- Process Assessment Model: Used to assess the effectiveness and maturity level of software processes. This model measures process performance based on specific criteria and metrics.
- Process Improvement Model: Provides guidance for improving the effectiveness of processes and guides improvement efforts through the planning, implementation, and evaluation stages.
The ISO/IEC 15504 standard competence levels are a measure used to assess the maturity and performance of processes:
Competence levels
- Level 0 (Initial): Processes are undefined or poorly defined.
- Level 1 (Managed): Processes are managed in specific projects.
- Level 2 (Defined): Processes are defined and documented according to organisational standards.
- Level 3 (Predictable): Processes are monitored and controlled based on measurable objectives.
- Level 4 (Optimised): Processes are continuously improved and performance is optimised.
ISO/IEC 15504 Standard Certification Process
The ISO/IEC 15504 certification process consists of the following steps:
- Initiation and Preparation: The documents required for certification are prepared and the processes to be evaluated are determined.
- Assessment and Audit: Software processes are evaluated in detail according to SPICE criteria.
- Reporting and Analysis: Assessment results are reported and areas for improvement are identified.
- Improvement and Reassessment: Necessary adjustments are made in areas for improvement and processes are reassessed.
Advantages of the ISO/IEC 15504 Standard
The ISO/IEC 15504 standard is a critical tool for improving software processes and determining their capabilities. By focusing on continuous improvement and process maturity levels, it enhances the quality and reliability of software processes.
