Development Assurance process

Titled Guidelines for Development of Civil Aircraft and Systems , this document addresses the development process of aircraft systems and the Development Assurance processes of (a) validation of requirements and (b) verification of the design implementation. 

Fig. 9.1 provides a simple illustration of the Development Assurance process, and each step is discussed in greater detail below. 

Development Assurance processes do not exist in isolation of system development processes. There are important information flows between them as illustrated in Fig. 9.4. These information flows are important to be understood, so that the developers... 

The food polymer science approach is being applied successfully in the food industry for understanding, improving, and developing food processes and products. However, to date, the glass transition generally remains more of a research and development tool than a routine quality assurance measure of food processability and stability. 

The International Standards Organization (ISO) definition of audit is Systematic, independent, and documented process for obtaining audit evidence and evaluating it objectively to determine the extent to which agreed criteria are fulfilled. The bottom-line goal of the software developer audit process is to allow you to assess the developer s quality assurance (QA) system. 

This FDA Orphan-Drug Review checklist has been designed in consultation with FDA reviewers, industry consultants, and regulatory professionals to serve as a summary tool indicating the evaluative criteria used by the Office of Orphan-Drug Development to critique and assess applications received. It can be used internally as a part of the Quality Assurance process, as a guideline for regulatory development of an application, and/or as a self-assessment tool to predict likely FDA response to an application. 

PAT is an automated quality-assurance process originally developed in the petrochemical industries. It is defined by three general principles continuous, cybernetic, and potentially remote monitoring of processes. 

But that sense of control can be regained and the result made rational and predictable through a careful Quality Assurance process that checks the submission against FDA established criteria and through the use of an internal, self-regulating review process that applies the checklist criteria used by the FDA to the submission development process. 

Conclusion. Successful implementation of a sustainable development mindset in an organization requires true integration of the values and principles behind sustainability, and not a shallow, cursory, stand-alone project. That is, sustainability is only one small piece of a larger approach to organizational responsibility in the global environment. The audit or assurance process is an important and valuable step in this approach that cannot and should not be overlooked. 

Operating limits are data driven, with the most critical measure being the process variation. They are established by working inward from the registration limits to provide assurance that we will not fail registration limits because of process or assay noise. At this stage of development the process variation will not be completely known, particularly in the hands of the plant, but the noise observed from the DOEs can be a reasonable starting point.

Often a device company will work closely with CDRH staff to develop and submit a combination device drug product, only to find out during the application review that upon consultation by the CDRH reviewer with CDER, new issues are brought up that could have been incorporated into the clinical study design. This points out the importance of early communication with all involved parties at FDA during product development. Assuring that representatives from both Review Divisions are present at FDA sponsor meetings allows for identification and discussion of issues early in the process. 

Short-lived radiopharmaceuticals have to be manufactured, quality-tested, and dispensed within a short time, adding constraint on safety procedures. In order to comply with the strict requirements of GMP, special methods for synthesis and in process quality control have been developed, assuring high quality of radiopharmaceuticals, without actually testing sterility and apyrogenicity before dispensing the labeled product. 

Of course, if a firm is ISO 9000 acaedited, this already speaks volumes about its commitment to quality, although the limitations of ISO 9001 to software development need to be clearly understood. These shortcomings have given rise to ISO 9000-3 (TickIT), to which over 1,000 firms have now been accredited however, this is a drop in the ocean when viewed against the industry as a whole. The consistent pattern of commercial success enjoyed by TicklT-accredited software houses is no coincidence and should be used by the auditor as a powerful endorsement of the benefits of a quality-assured process in securing the future prosperity of a firm involved in any way with software development. 

To provide confidence that the project will achieve the required quality level, a queiUty assurance process is implemented. By continuously reviewing (or auditing) the actual implementation of the plan developed during quality planning, qirahty assurance systematically seeks to increase the effectiveness and efficiency of the project and its results. 

Definition of SAV Development Assurance objectives as they relate to the SAV hfecycle processes, including the relationship between DAL, applicable objectives, independence, and SAV lifecycle data. 

Provide guidance for Design Assurance activities to meet the Development Assurance objectives. It does allow flexibility in choice of processes necessary to meet the objectives of this document as new process technologies become available. 

ARP4754A (paragraph 3.1) refers to Development Assurance , which establishes confidence that system development has been accomplished in a sufficiently disciplined manner to limit the likelihood of development errors that could impact aircraft safety . Development Assurance is defined as a process involving specific planned and systematic actions that together provide confidence that errors or omissions in requirements or design have been identified and corrected to the degree that the system, as implemented, satisfies applicable certification requirements . 

The Safety Assessment process assigns the DAL as explored in Step 1 (Section 9.2.1) mentioned earlier. The development assurance outputs from the Safety Assessment process is summarised in Table 9.16.
