- In market-driven software development, release planning is one of the most critical tasks. Selecting a subset of requirements for realisation in a certain release is as complex as it is important for the success of a software product. Despite this, the literature provides little information on how release planning is done in practice. We designed, implemented and evaluated a support tool for release planning as a means for provoking a rich understanding of the task of release planning. The tool utilises a selection algorithm which, based on value, resource estimate and interdependencies, presents a number of valid and good release suggestions. The initial attempt at supporting release planning proved to be based on an overly simplistic and structuralistic view. The results provide ample evidence that the task could be characterised as a wicked problem, which in turn has several implications for the support needed. Although the provotype could indeed support the planner, in its current version it has several serious shortcomings related to the degree of interactivity, underlying models, presentation of information and general appearance. A rich description of the task of release planning is provided. Based on these findings, a list of design implications is proposed, which is intended to guide the future design of a support tool for release planning.

- When modelling inter-organisational workflow it is important not to make assumptions such as with regard to the formats of the data exchanged between the workflow participants or the technical infrastructures and platforms, as they can restrict the range of possible workflow management implementations. The approach presented in this paper allows for the conceptual modelling of workflow processes using primitive constructs such as nodes, rules and business documents. The paper presents both a graphical notation for modelling workflows as well as a mapping of the workflow constructs to XML models that follows the Workflow Management Coalition interoperability standards. This allows the modelled workflow to be interpreted and executed by a variety of workflow engines.

A Feasibility Study of Automated Support for Similarity Analysis of Natural Language Requirements in Market-Driven Development

- In market-driven software development there is a strong need for support to handle congestion in the requirements engineering process, which may occur as the demand for short time-to-market is combined with a rapid arrival of new requirements from many different sources. Automated analysis of the continuous flow of incoming requirements provides an opportunity to increase the efficiency of the requirements engineering process. This paper presents empirical evaluations of the benefit of automated similarity analysis of textual requirements, where existing information retrieval techniques are used to statistically measure requirements similarity. The results show that automated analysis of similarity among textual requirements is a promising technique that may provide effective support in identifying relationships between requirements.

An industrial case study on distributed prioritisation in market-driven requirements engineering for packaged software
- 2001

Tidskriftsartikel (refereegranskat)abstract
- When developing packaged software, which is sold `off-the-shelf' on a worldwide marketplace, it is essential to collect needs and opportunities from different market segments and use this information in the prioritisation of requirements for the next software release. The paper presents an industrial case study where a distributed prioritisation process is proposed, observed and evaluated. The stakeholders in the requirements prioritisation process include marketing offices distributed around the world. A major objective of the distributed prioritisation is to gather and highlight the differences and similarities in the requirement priorities of the different market segments. The evaluation through questionnaires shows that the stakeholders found the process useful. The paper also presents novel approaches to visualise the priority distribution among stakeholders, together with measures on disagreement and satisfaction. Product management found the proposed charts valuable as decision support when selecting requirements for the next release, as they revealed unforeseen differences among stakeholder priorities. Conclusions on stakeholder tactics are provided and issues of further research are identified, including ways of addressing identified challenges
