The notion of calendar mining is introduced and support is provided for performing the measurement by a reference data model and queries for all metrics defined.

Developer support chat is used to provide internal support to other development teams. The report shows how a fundamental data analysis helped to identify gaps and action items to boost performance of a development team by reducing time spent on developer support chat and minimizing interrupts from other developer teams. The report also shows an example of how a root cause analysis can be supported by simple data analysis in finding process improvement opportunities.

First of all it has to be decided which approaches have potential for the organization. In many cases one approach does not contain enough information for process implementation. Consequently, the organization may need to use several approaches and the decision has to be made how the chosen approaches can be used simultaneously. This area is called Multi-model Software Process Improvement (MSPI). The simultaneous usage of multiple quality approaches is called the multi-model problem. In this dissertation we propose a solution for the multi-model problem which we call the Process Based Unification (PBU) framework. The PBU framework consists of the PBU concept, a PBU process and the PBU result. We cal...

Despite a systematic improvement requires mapping of quality approaches to organizational processes and data shall be stored in a well-designed manner, storing multimodel results is not yet addressed in detail in the current literature. In this report we present a data model for multimodel software process improvement which allows storing multimodel results in a maintainable way.

Manual processing of information consumes plenty of resources. In this report we present a text mining approach applied on CMMIone well known and widely known quality approach. The text mining analysis can provide a quick overview on the scope of a quality approaches. The result of the analysis could accelerate the understanding and the selection of quality approaches.

Manual processing of information consumes plenty of resources. In this report we present the complexity analysis of CMMI – one well known and widely process improvement framework. The complexity analysis can provide a quick overview on the coupledness of the elements of quality approaches by an automated analysis of the cross-references in quality approaches. The result of the analysis could accelerate the understanding the quality approach and help in setting the starting points of improvement.

A technical support chat is established and used to provide internal developer support to other development teams which use the software code developed by a core team. The paper shows how data analysis of a 6 months support time helped to identify gaps and action items for improving the technical support process to minimize interrupts from other developer teams. The paper also shows effects (advantages and drawbacks) of refactor actions taken based on this analysis.

The framework helps the quality assurance experts making objective and comparable decisions in software projects by defining and assessing measurable quality goals and thresholds, directly relating these to an escalation mechanism. First results of applying the proposed measurement based software quality framework in a real life case study are also addressed in this report.

We focus on presenting the structure of quality approaches emphasizing the similarities amongst them. Understanding the structure of quality approaches helps supporting organizations in using multiple quality approaches and methods in the same time.

UML activity diagrams, EPCs and BPMNs are compared based on well-defined criteria: intelligibility, ability of expressing process elements and workflow patterns, software support, portability and widespread. Both the criteria and the rationale of the final selection can be used as a basis for selecting a process modeling language for other projects in the industry.
