The situational factors that affect the software development process: Towards a comprehensive reference framework

Context

An optimal software development process is regarded as being dependent on the situational characteristics of individual software development settings. Such characteristics include the nature of the application(s) under development, team size, requirements volatility and personnel experience. However, no comprehensive reference framework of the situational factors affecting the software development process is presently available.

Objective

The absence of such a comprehensive reference framework of the situational factors affecting the software development process is problematic not just because it inhibits our ability to optimise the software development process, but perhaps more importantly, because it potentially undermines our capacity to ascertain the key constraints and characteristics of a software development setting.

Method

To address this deficiency, we have consolidated a substantial body of related research into an initial reference framework of the situational factors affecting the software development process. To support the data consolidation, we have applied rigorous data coding techniques from Grounded Theory and we believe that the resulting framework represents an important contribution to the software engineering field of knowledge.

Results

The resulting reference framework of situational factors consists of eight classifications and 44 factors that inform the software process. We believe that the situational factor reference framework presented herein represents a sound initial reference framework for the key situational elements affecting the software process definition.

Conclusion

In addition to providing a useful reference listing for the research community and for committees engaged in the development of standards, the reference framework also provides support for practitioners who are challenged with defining and maintaining software development processes. Furthermore, this framework can be used to develop a profile of the situational characteristics of a software development setting, which in turn provides a sound foundation for software development process definition and optimisation.     

Efficiency of CAMEtools in software quality assurance

Our paper describes the requirements and possibilities of integration of metrics tools in the field of software quality assurance. Tools for the support of the measurement process are herein classified as Computer Assisted Software Measurement and Evaulation Tools (CAMETools). Software measurement regarded as a special type of metrics application provides a great amount of basic information for the evaluation of the software development process or the software product itself. Our paper examines the effectiveness and destination of software measurement in tool-based software development and is based on an analysis of more than 20 CAME tools in the Software Measurement Laboratory at the University of Magdeburg. CAMEtools are useable for the process, product, and resources evaluation in all phases of the software life cycle (including the problem definition) for different development paradigms. The efficiency of CAME tools is described on the basis of a general measurement framework. This framework includes all steps in the software measurement and evaulation process: metrics definition, selection of the evaluation criteria, tool-based modelling and measurement, value presentation and statistical analysis. The framework includes the main aspects of the process evaluation techniques (Capability Maturity Model, ISO 9000-3 etc.) and product evaluation (ISO 9126, etc.). It is not a disjointed set of aspects: our measurement framework represents an incremental technique for the application of quantification of quality aspects in a required quality assurance

Offshore outsourcing of software development and maintenance: A framework for issues

Frameworks intended for identifying and organizing issues associated with offshore outsourcing of software development have focused on project or site selection. Existing frameworks are not comprehensive because they do not fully address one or more of the following issues: (1) the relationship between project characteristics and site suitability, (2) financial and intellectual property issues in the context of software development, and (3) the role of agents outside the outsourcing and vendor firms in the offshore outsourcing process. To overcome these limitations, we propose a more comprehensive framework that links projects (which require resource) and sites (which possess resources). It also includes environmental agents whose actions affect resource availability at the sites. The framework serves as an useful tool to systematically address the issues that arise in the context of offshore outsourcing of software development. We use the framework to review and classify existing literature.

Leveraging global resources: a process maturity framework for managing distributed development

The popular and well-tested software process frameworks such as the Software Engineering Institute's Capability Maturity Model and ISO 9001, details key process areas for software development. Focusing more on continuous improvement in code development processes, generic-process frameworks such as the CMM lack key process areas (KPA) that address capabilities for managing distributed software projects, such as establishing mutual knowledge and managing geographically dispersed social networks. We identify 24 new KPAs that address the wide-ranging capabilities needed for managing distributed software development and arrange them in an evolutionary order similar to the CMM framework. The evolutionary or phased approach in improving software management capabilities helps firms systematically assess their situations and plan for improvements. We also report the results of a statistically tested maturity assessment survey and test the overall rigor of our model against industry expert opinion and objective data collected from real-world projects implemented at SAP AG, a leading global-enterprise software firm.
