Software Systems In-House Integration : Observations and Guidelines Concerning Architecture and Process
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Software evolution is a crucial activity for software organizations. A specifc type of software evolution is the integration of previously isolated systems. The need for integration is often a consequence of different organizational changes, including merging of previously separate organizations. One goal of software integration is to increase the value to users of several systems by combining their functionality, another is to reduce functionality overlap. If the systems are completely owned and controlled in-house, there is an additional advantage in rationalizing the use of internal resources by decreasing the amount of software with essentially the same purpose. Despite in-house integration being common, this topic has received little attention from researchers. This thesis contributes to an increasing understanding of the problems associated with in-house integration and provides guidelines to the more efficient utilization of the existing systems and the personnel.In the thesis, we combine two perspectives: software architecture and processes. The perspective of software architecture is used to show how compatibility analysis and development of integration alternatives can be performed rapidly at a high level of abstraction. The software process perspective has led to the identification of important characteristics and practices of the integration process. The guidelines provided in the thesis will help those performing future in-house integration to make well-founded decisions timely and efficiently.The contributions are based on several integration projects in industry, which have been studied systematically in order to collect, evaluate and generalize their experiences.

- We validated the new European Organisation for Research and Treatment of Cancer Quality of Life Head and Neck Module (EORTC QLQ-HN43).We enrolled 812 patients with head and neck cancer from 18 countries. Group 1 completed the questionnaire before therapy, and 3 and 6 months later. In group 2 (survivors), we determined test-retest reliability using intraclass correlation coefficients (ICC). Internal consistency was assessed using Cronbach's Alpha, the scale structure with confirmatory factor analysis, and discriminant validity with known-group comparisons.Cronbach's alpha was >0.70 in 10 of the 12 multi-item scales. All standardized factor loadings exceeded 0.40. The ICC was >0.70 in all but two scales. Differences in scale scores between known-groups were >10 points in 17 of the 19 scales. Sensitivity to change was found to be sufficient in 18 scales.Evidence supports the reliability and validity of the EORTC QLQ-HN43 as a measure of quality of life.

Konferensbidrag (refereegranskat)abstract
- Making software developers work towards a common goal may be likened to herding cats. If we further spread developers around the globe, we run increased risks of being unable to design and impose coherent software architectures on projects, potentially leading to lower quality of the resulting systems. Based on our experiences in a large, distributed research and development project, PalCom, we propose that employing techniques from active user involvement in general (and from participatory design in particular) may help in designing and sharing quality software architectures. In particular, we present the Traveling Architects technique in which a group of architects visit development locations in order to engage developers and end users in software architecture work. We argue that using techniques such as these may potentially lead to higher quality of software architectures in particular for systems developed in a distributed setting.
