[Context] Outsourced information systems development (ISD) represents an important and widely used software delivery strategy for mid-size and large non-IT companies. In such companies, testing activities are conducted by a contracted party, and are hidden from continuous checks on the part of the client, who is typically only provided with insight during the system hand-over. Such an approach is risky; the testing activities might be executed in a loose and sloppy manner by the contractor. Consequently, the risk of unsatisfactory quality may be shifted de-facto to the client, who will bear any negative consequences (e.g., project delays, increased effort) during user acceptance testing (UAT). [Objective] The main objective of this doctoral dissertation is to design and evaluate a management artefact - Test Governance Framework (TeGoF) - that can be used by the client company; the framework thus focuses on client's perspective on exercising control. To this end, the artefact is evaluated in the context of three outsourced ISD projects. [Method] The research is grounded in control theory, which originates in organizational studies. The principles of design science were applied in the development of the TeGoF, and the principles of ethnographically informed action research were used to evaluate the management artefact. This form of evaluation underscores the social dimension of the problem. In particular, the concepts of trust, control, and power are examined using an interpretive epistemological position. [Results] Of a total of three projects, the TeGoF was applied successfully in only one case. A detailed analysis describes the factors contributing to the difficulties implementing the TeGoF principles in the two remaining projects. The resulting interpretation stresses the fact that such difficulties were caused by differences among the contexts in which the evaluation took place. Specifically, there were varying dynamics of the abovementioned factors of trust, control, and power. [Conclusion] The contribution of this doctoral dissertation consists in (1) the development of the TeGoF as a tool that pinpoints significant limitations in the current research related to control issues in the domain of outsourced ISD; (2) the evaluation of the TeGoF and analysis of the key success factors; and (3) a proposal of a novel methodological approach combining design science research with ethnographically informed action research.

Vývoj a implementace testovací platformy

The quality is probably the most significant property of a successful software product. As experience with many software projects has already shown, leaving out testing and quality management from software development process can result in vast and critical customer issues, which usually invoke additional expenses for the software production company. In the course of time, software testing as a discipline has therefore seized an important position among other software development activities. And due to the fact that the software, thanks to rising customer demands and growing competing products portfolio, is getting more complex, the more advanced software testing procedures need to be implemented. Test strategy and iteration planning, implementation of multiple test types into the test suite, test automation, evaluation, administration and maintenance: these activities are commonly required within larger software development projects. Formalized software testing is, nevertheless, being introduced also to projects using agile management techniques which, by management decision or target user industry, are supposed to deliver products of highest quality. This initiates the high focus on the software testing discipline. The purpose of this thesis is to design and implement a new system of software testing within a real project in the CertiCon a.s. company, for which software development is the main business activity. Current issues and gaps for possible improvement, gathered both by project management and the author himself, are analyzed in the first major part of this work and transformed into testing system requirements, which should cover both process changes as well as implementation/development of needed software supporting the process. The second part of thesis is covering the design of the new software testing system, focusing mainly on the area of test management and selection of appropriate software management tool. The final part of the thesis is aimed at implementation of the designed solution within a real organization environment and evaluates its benefits against the previously set requirements.
