Software development process

These abstraction layers offer tremendous benefits to the software development process with reduced development complexity and costs and increased productivity. Application server platforms and blueprints also provide software development frameworks to help the software fit into specific architecture patterns. One of the most commonly adopted software architecture patterns for enterprise systems is the layered architecture (Buschmann et al., 1996 Fowler, 2003a). It is also the heart of the J2EE blueprint (Alur et al., 2003). 

In a mature software development environment, software is developed as individual components or small units. Each unit is tested individually and integrated with other units to form a module. The accurate implementation of each module is achieved by following the technical design specification deliverable. The output of the software development process is an assembled system. 

It is often tempting to implement tools to support design techniques as part of the system/software development processes. Care must be taken, however, not to get carried away with technology. Many tools that promise improved productivity and quafity are in the market. While these tools may be designed to support particular development techniques/processes, they are often used out of context. In consequence, the tools are not exploited fully and may even be misused. The promised benefits may not materialize. 

The FDA will consider the lack of computer validation as a significant inspection finding and log it as a 483 noncompliance citation. The MHRA may take a more lenient view depending on the criticality of the system on GxP operations. The lack of a detailed written description of an individual computer system (kept up to date with controls over changes), its functions, security and interactions (EU GMP Annex 11.4) a lack of evidence for the quality assurance of the software-developed process (EU GMP Annex 11.5), coupled with a lack of adequate validation evidence to support the use of GxP-related computer systems may very well be either a critical or major deficiency. Ranking will depend on the inspector s risk assessment.

It should be said that integration of existing, extended, and newly built environments for one location and their further integration to a distributed overall environment results in a big software development process and project for tool construction/extension/integration within IMPROVE. The underlying question is practical as well as big and, therefore, needs software engineering and architectural knowledge. The solution we have achieved leaves the size and lucidity of textbook examples. 

Due to the realization effort of the challenging approach of IMPROVE this can only mean that we do not aim at case-dependent solutions. Instead, we are looking for a framework of reusable components (dark grey parts of Fig. 1.8) and a carefully structured software development process to get a distributed overall environment by making use of the framework. 

The term software architecture is defined as a description of the structure of the components of a program/system (and) their interrelationships [331, 686[. This description serves different purposes, e.g. for analyzing certain software qualities, such as adaptability, maintainability, or portability, or managing the software development process [536]. 

The role of the subproject 13 of IMPROVE, as described in Sect. 5.7, was to coordinate the software development process of the integrated engineering design environment (cf. Fig. 5.55 on p. 558). Especially, it dealt with the development of a general framework for a-posteriori integration of existing tools.

Standardized directory structures for source code, documentation hies, hnal executables, conhguration hies, and model inputs/outputs allow tracking the software development process and also help in easily integrating multiple, independently developed modules. Standardized directory structures allow easy detection of con-hicts in the names of functions, scripts, or conhguration hies. 

Documentation concerns basically two areas (1) specification documents — produced during software development process — covering for the internal design of software for the purpose of future maintenance and enhancement (2) documentation addressing the application of the software, such as user guides, reference manuals, training documentation, and release notes. 

The V-model was developed in 1992 to regulate the software development process within the German federal administration. It was extended in 1997, called the V-model 97, and the most current version, V-model XT, was finalized in Eebruary 2005 [5],... 

With this information about the software development process, we will now look at some general concepts of data and knowledge management. 

In this context, multiple methods for supporting the software development process have been developed. They differ according to their focus on the various software development processes and their preferred approach regarding the issue at hand, such as data, event, or function orientation, respectively. 

Coordination The fragmentation and stovepiping in the flight software development process, coupled with the lack of comprehensive and defined system and safety engineering processes, resulted in poor and inadequate communication and coordination among the many partners and subprocesses. 

Safety Constraint Effective software development processes must be established and monitored. System safety processes must be created to identify and manage system hazards.
