DO-178C Certification Process & Planning

DO-178C Certification Process & Planning

Table of Contents

Introduction

DO-178C, also known as Software Considerations in Airborne Systems and Equipment Certification, is a widely recognized standard for the certification of software used in airborne systems. Developed by the Radio Technical Commission for Aeronautics (RTCA), DO-178C provides guidelines and objectives for the software development process to ensure safety and reliability in aviation systems. This article will discuss the DO-178C certification process and highlight important plans that must be considered for successful certification.

DO-178C Certification Process

The DO-178C certification process consists of several key activities that need to be performed in a systematic and well-documented manner. The following are the major steps involved in the certification process:

Software Planning

Software planning is the initial phase of the DO-178C certification process. It involves defining the software development life cycle, including processes, tools, and resources required for software development. The planning phase also includes the identification of software levels (DAL A to E) and associated objectives, tasks, and artifacts.

Software Development

In the software development phase, the actual coding and testing of the software take place. The development activities should comply with the defined software development life cycle, including requirements capture, design, coding, verification, and validation. The software should be developed using a process that ensures high-quality and reliable code.

Software Verification

Software verification is a critical phase in the certification process. It involves conducting various activities to demonstrate that the software satisfies its intended requirements and functions correctly. Verification activities include requirements-based testing, structural coverage analysis, and code reviews. The objective is to identify and fix any potential defects in the software.

Software Configuration Management

Software configuration management (SCM) is essential for maintaining control over the software throughout its life cycle. It involves managing software baselines, controlling changes, and ensuring the integrity of the software artifacts. SCM activities include configuration identification, version control, change management, and release management.

Software Quality Assurance

Software quality assurance (SQA) focuses on ensuring that the software development processes and activities are performed correctly. SQA activities include process audits, documentation reviews, and compliance assessments. The goal is to identify any deviations from the defined processes and take corrective actions to maintain the quality of the software.

Software Certification

The software certification phase involves the preparation of certification artifacts and documentation required by the certification authorities. These artifacts demonstrate compliance with the objectives and requirements of DO-178C. The certification package typically includes the software plans, development and verification records, test procedures and results, and other supporting documentation.

Important Plans for DO-178C Certification

To achieve DO-178C certification, it is crucial to develop and execute several plans that address specific aspects of the software development process. The following plans should be considered during the certification process:

Software Development Plan (SDP)

The Software Development Plan outlines the overall strategy for software development and describes the software development life cycle, processes, and procedures. It defines the roles and responsibilities of the development team and provides an overview of the software configuration management and quality assurance activities.

Software Verification Plan (SVP)

The Software Verification Plan details the activities and techniques to be used for verifying and validating the software. It defines the test strategies, test environments, test procedures, and the criteria for determining the successful completion of verification activities. The SVP also specifies the requirements-based testing and structural coverage analysis to be performed.

Software Configuration Management Plan (SCMP)

The Software Configuration Management Plan outlines the procedures for managing software configuration items, controlling changes, and ensuring the integrity of the software baselines. It describes the version control system, configuration identification scheme, and the process for handling configuration changes and releases.

Software Quality Assurance Plan (SQAP)

The Software Quality Assurance Plan describes the activities and processes to ensure that the software development adheres to the defined standards and objectives. It outlines the procedures for conducting process audits, documentation reviews, and compliance assessments. The SQAP also includes the metrics for measuring software quality and the corrective action process.

Software Tool Qualification Plan (STQP)

The Software Tool Qualification Plan addresses the qualification of software development and verification tools used during the development process. It defines the process for tool selection, verification, and validation to ensure that the tools do not introduce errors or deviations from the required standards.
