“…They also state that each product variant has its specific considerations regarding appropriate requirements, risks and costs. Cortellessa et al, present a framework supporting the choice between selection of commercial component software and development in-house (Cortellessa et al, 2008). Daneshgar et al have examined, in relation to the 'make or buy' decision on the basis of 10 existing decision criteria, additional criteria that affect small and medium businesses (Daneshgar et al, 2013).…”

“…Component-based software development is often used to deal with this challenge but the selection of appropriate software components then becomes an important decision (Jha et al, 2014). A component can be defined as a coherent package of software that can be independently developed and delivered as a unit, and that offers interfaces by which it can be connected, unchanged, with other components to compose a larger system (D 'Souza and Wills, 1997 Choosing between these options is not obvious (Cortellessa et al, 2008). However, we were unable to find a good overview of criteria that could be used for such a decision.…”

ICEIS 2016 received 257 paper submissions from 42 countries in all continents, which makes it one of the largest conferences in the World in the area of Information Systems, thus demonstrating the success and global dimension of this conference. From these, 42 papers were selected for publication and presentation at the Conference as full papers. These numbers, leading to a full-paper acceptance ratio of 16%, show the intention of preserving a high quality forum for this conference, a quality that we intend to maintain in the future, for the next editions of this conference.The high number and high quality of the received papers imposed difficult choices in the selection process. To evaluate each submission, a double blind paper review was performed by the Program Committee, whose members are highly qualified researchers in ICEIS topic areas.All presented papers will be available at the SCITEPRESS Digital Library and will be submitted for indexation by Thomson Reuters Conference Proceedings Citation Index (ISI), INSPEC, DBLP, EI (Elsevier Index) and Scopus.Additionally, a short list of presented papers will be selected to be expanded into a forthcoming book of ICEIS 2016 Selected Papers to be published by Springer in the LNBIP Series.The technical program of the conference included a panel and 4 invited talks delivered by internationally distinguished speakers, namely: Claudia Loebbecke (University of Cologne, Germany), Sergio Gusmeroli (TXT e-solutions SPA, Italy), Wil Van Der Aalst (Technische Universiteit Eindhoven, Netherlands) and Jan Vom Brocke (University of Liechtenstein, Liechtenstein). Their participation positively contributes to reinforce the overall quality of the Conference and to provide a deeper understanding of the fields addressed by the conference.Moreover, ICEIS 2016 had a Doctoral Consortium on Enterprise Information Systems and 1 tutorial. We are thankful to the Conference Co-chairs (Olivier Camp and José Cordeiro) and Program Co-chairs (Slimane Hammoudi, Leszek Maciaszek and Michele M. Missikoff) for their dedication and hard work in organizing these events.We sincerely thank all the authors for their submissions and participation in ICEIS 2016. Furthermore, we would like to thank all the members of the program committee and reviewers, who helped us with their expertise, dedication and time. We would also like to thank the invited speakers for their excellent contribution in sharing their knowledge and vision and the workshop/special session chairs whose collaboration with ICEIS 2015 was much appreciated. Finally, we gratefully acknowledge the professional support of the ICEIS 2016 team for all organizational processes. XIIIWe hope that all colleagues find this a fruitful and inspiring conference. We hope to contribute to the development of the Enterprise Information Systems community and look forward to having additional research results presented at the next edition of ICEIS, details of which are available at http://www.iceis.org.

“…In the following discussion of make-or-buy literature, we focus on normative make-or-buy approaches for IT services (e.g., components, modules) or especially web services, as the sell option we consider in this paper is only relevant for IT/web services that are tradable on a market. For instance, Cortellessa et al [21] investigate whether a firm should buy commercial offthe-shelf components or develop them in-house. They incorporate costs as well as quality attributes in a non-linear cost-quality optimization model and also consider the architecture of the intended software system.…”

Abstract:The emergence of the web service market has enabled firms to choose between developing web services internally and purchasing them externally from web service providers. In general, these socalled make-or-buy decisions have been the object of intense debate in the IT outsourcing literature.However, characteristics of web services such as loose coupling and the current trend of digitalizing application interfaces enable new opportunities especially to non-software firms: when a firm decides to develop a web service internally (make-decision) it has the option of exposing and selling the use of this web service after its internal development (sell option). In this paper, we propose a normative approach for the valuation of such a sell option based on real option theory, taking into account the characteristics of web services. This approach enhances traditional make-or-buy approaches by additionally considering this sell option in decision-making. Our results are twofold: (I) the sell option has considerable impact on traditional make-or-buy decisions and makes the internal development of web services more attractive; (II) it is preferable to execute the sell option as soon as possible after completion of the internal development of the web service.

“…The actual decision-making is often done using optimization approaches [7], [8], in particular when the trade-off is between two properties such as cost and reliability [9].…”

“…Assuming for the sake of the argument that the estimates problem is solved (which it most certainly is not), this means that each alternative software product -each option on the decision maker's table -can be characterized by an 8-dimensional vector. Also assuming that the properties can all be measured and mapped onto a scale of, say, 0-10, the problem becomes one of selecting between alternatives of the form A = (10, 10, 2, 10, 10, 5, 8, 1), B = (4,9,8,10,7,0,8,9), C = (7,8,7,4,7,2,7,0). This is a complex problem.…”

Characterization of trade-off preferences between non-functional properties

Efficient design and evolution of complex software intensive systems rely on the ability to make informed decisions as early as possible in the life cycle.Such informed decisions should take both the intended functional and nonfunctional properties into account. Especially regarding the latter, it is both necessary to be able to predict properties and to prioritize them according to well-defined criteria. In this paper we focus on the latter problem, that is to say how to make trade-offs between non-functional properties of software intensive systems. We provide an approach based on the elicitation of utility functions from stake-holders and subsequent checks for consistency among these functions. The approach is exploitable through an easy-to-use GUI, which is also presented. Moreover, we describe the setup and the outcome of our two-fold validation based on exploratory elicitations with students and practitioners.
