- Quality requirements play a critical role in driving architectural design and are an important issue in software development. Therefore, quality requirements need to be considered, specified, and quantified early during system analysis and not later in the development phase in an ad-hoc fashion. This paper presents the quality performance model that estimates quality targets in relation to market expectations as a basis for the architecting of quality requirements. The purpose of the model is to provide concepts for qualitative reasoning of quality levels in the decision-making of setting actual targets of quality requirements for coming releases of the product. The quality performance model is evaluated at one case company, using a market-driven development approach, in the electronic payment-processing domain. The results show that the model is useful for supporting early decisionmaking in, e.g., release planning of quality requirements

Enterprise Architecture for Information System Analysis : Modeling and assessing data accuracy, availability, performance and application usage
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Decisions concerning IT systems are often made without adequate decision-support. This has led to unnecessary IT costs and failures to realize business benefits. The present thesis presents a framework for analysis of four information systems properties relevant to IT decision-making. The work is founded on enterprise architecture, a model-based IT and business management discipline. Based on the existing ArchiMate framework, a new enterprise architecture framework has been developed and implemented in a software tool. The framework supports modeling and analysis of data accuracy, service performance, service availability and application usage. To analyze data accuracy, data flows are modeled, the service availability analysis uses fault tree analysis, the performance analysis employs queuing networks and the application usage analysis combines the Technology Acceptance Model and Task-Technology Fit model. The accuracy of the framework's estimates was empirically tested. Data accuracy and service performance were evaluated in studies at the same power utility. Service availability was tested in multiple studies at banks and power utilities. Data was collected through interviews with system development or maintenance staff. The application usage model was tested in the maintenance management domain. Here, data was collected by means of a survey answered by 55 respondents from three power utilities, one manufacturing company and one nuclear power plant. The service availability studies provided estimates that were accurate within a few hours of logged yearly downtime. The data accuracy estimate was correct within a percentage point when compared to a sample of data objects. Deviations for four out of five service performance estimates were within 15 % from measured values. The application usage analysis explained a high degree of variation in application usage when applied to the maintenance management domain. During the studies of data accuracy, service performance and service availability, records were kept concerning the required modeling and analysis effort. The estimates were obtained with a total effort of about 20 man-hours per estimate. In summary the framework should be useful for IT decision-makers requiring fairly accurate, but not too expensive, estimates of the four properties.

Automated Identification of Yellow Flags and Their Signal Terms in Physiotherapeutic Consultation Transcripts
- 2023
-
Ingår i: Proceedings of the 16th International Joint Conference on Biomedical Engineering Systems and Technologies BIOSTEC - (Volume 5). - : SciTePress. - 9789897586316 ; , s. 530-537

Konferensbidrag (refereegranskat)abstract
- This paper investigates the possibility of automating the process of identifying yellow flags and their signal terms in physiotherapeutic consultation transcripts from patients with low back pain, using Automated Text Identification. It is part of the Automated Medical Reporting research domain. In physiotherapy focused on low back pain, yellow flags are considered psycho-social predictors of poor recovery and risk factors for chronic disability development. This paper uses a 6-step mixed method approach. Consultation transcripts and yellow flag assessment guidelines were collected, an automated identification tool was built and the OSPRO assessment guideline was used to test the tool for accuracy. It was found that it is possible to identify Yellow Flags and their Signal Terms automatically with the tool developed in this experiment. However, this is just the beginning, and much more research must be done in the future to further enhance the tool, mainly to improve precision.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In today’s digital environment companies are forced to participate in a process often coined digital transformation. As a result, companies expect to stay relevant and harness digital technologies for their competitive advantage and sustainable value creation. A central element of this transforming process is the software that companies develop, purchase or customize in order to support their business. These challenges stretch beyond the information and technology industry, as businesses use digital technology to compete in traditions industries. Popular examples are omnipresent, with Uber revolutionizing the taxi industry, AirBnB forcing new legislations to protect the hotel industry, and Spotify becoming a single source for music with a monthly subscription model. The Dagstuhl Seminar “Software Business, Platforms, and Ecosystems: Fundamentals of Software Production Research” organized by Pekka Abrahamsson, Jan Boch, Sjaak Brinkkemper, and Alexander Mädche took place from 29th of April until 02nd of May. The seminar’s objectives were i) to strengthen crosscommunity research efforts, ii) to increase accessibility of research data and results, iii) to exchange on current and future research developments and discussions, iv) to initiate project ideas between scholars and with industry that evolve into project proposals.

Exploring factors affecting decision outcome and lead time in large-scale requirements engineering
- 2015
-
Ingår i: Journal of software: Evolution and Process. - : Wiley. - 2047-7481 .- 2047-7473. ; 27:9, s. 647-673

Tidskriftsartikel (refereegranskat)abstract
- Lead time, defined as the duration between the moment a request was filed and the moment the decision was made, is an important aspect of decision making in market-driven requirements engineering. Minimizing lead time allows software companies to focus their resources on the most profitable functionality and enables them to remain competitive within the quickly changing software market. Achieving and sustaining low decision lead time and the resulting high decision efficiency require a better understanding of factors that may affect both decision lead time and outcome. In order to identify possible factors, we conducted an exploratory two-stage case study that combines the statistical analysis of seven possible relationships among decision characteristics at a large company with a survey of industry participants. Our results show that the number of products affected by a decision increases the time needed to make a decision. Practitioners should take this aspect into consideration when planning for efficient decision making and possibly reducing the complexity of decisions. Our results also show that when a change request originates from an important customer, the request is more often accepted. The results provide input into the discussion of whether a large company should focus on only a few of its large customers and disregard its significantly larger group of small customers. The results provide valuable insights for researchers, who can use them to plan research of decision-making processes and methods, and for practitioners, who can use them to optimize their decision-making processes. In future work, we plan to investigate other decision characteristics, such as the number of stakeholders involved in the discussion about the potential change or the number of dependencies between software components.

Modularization constructs in method engineering : towards common ground?
- 2007

Ingår i: Situational method engineering. - Berlin : Springer. - 9780387739465 ; , s. 359-368

Konferensbidrag (refereegranskat)abstract
- Although the Method Engineering (ME) research community has reached considerable maturity, it has not yet been able to agree on the granularity and definition of the configurable parts of methods. This state of affairs is causing unnecessary confusion, especially with an ever increasing number of people contributing to ME research. There are several competing notions around, most significantly ‘method fragments’ and ‘method chunks’, but also ‘method components’ and ‘process components’ are used in some quarters and have also been widely published. Sometimes these terms are used interchangeably, but there appears to be important semantic and pragmatic differences. If the differences are unimportant, we should be able to come to an agreement on what construct to promote. Alternatively, the different constructs may serve different purposes and there is a need for them to coexist. If this is the case, it should be possible to pinpoint exactly how they are related and which are useful in what contexts. This panel is a step towards finding common ground in this area, which arguably is at the very core of ME.
