social ties knowledge sharing and successful collaboration in globally distributed system Development Projects
European Journal of Information Systems, 2005Co-Authors: Julia Kotlarsky, Ilan OshriAbstract:Traditionally, the main focus of the information system (IS) literature has been on technical aspects related to system Development Projects. Furthermore, research in the IS field has mainly focused on co-located project teams. In this respect, social aspects involved in IS Projects were neglected or scarcely reported. To fill this gap, this paper studies the contribution of social ties and knowledge sharing to successful collaboration in distributed IS Development teams. Data were drawn from two successful globally distributed system Development Projects at SAP and LeCrov. Data collected were codified using Atlas.ti software. The results suggest that human-related issues, such as rapport and transactive memory, were important for collaborative work in the teams studied. The paper concludes by discussing the implications for theory and suggesting a practical guide to enhance collaborative work in globally distributed teams.

a procedure to detect problems of processes in software Development Projects using bayesian networks
Expert Systems With Applications, 2015Co-Authors: Mirko Perkusich, Hyggo Almeida, Gustavo Soares, Angelo PerkusichAbstract:We present a procedure to assist on software process management.The procedure uses Bayesian networks to detect processes' problems.The procedure was successfully applied to Scrum-based software Projects.The application was validated through case studies in two companies.Using the procedure should increase software project's success rate. There are several software process models and methodologies such as waterfall, spiral and agile. Even so, the rate of successful software Development Projects is low. Since software is the major output of software processes, increasing software process management quality should increase the project's chances of success. Organizations have invested to adapt software processes to their environments and the characteristics of Projects to improve the productivity and quality of the products. In this paper, we present a procedure to detect problems of processes in software Development Projects using Bayesian networks. The procedure was successfully applied to Scrum-based software Development Projects. The research results should encourage the usage of Bayesian networks to manage software processes and increase the rate of successful software Development Projects.

SAC - A model to detect problems on scrum-based software Development Projects
Proceedings of the 28th Annual ACM Symposium on Applied Computing - SAC '13, 2013Co-Authors: Mirko Perkusich, Hyggo Almeida, Angelo PerkusichAbstract:There is a high rate of software Development Projects that fails. Whenever problems can be detected ahead of time, software Development Projects may have better chances of success, and therefore save money and time. In this paper, we present a probabilistic model to help ScrumMasters to apply Scrum in organizations. The model's goal is to provide information to the project's ScrumMaster to help him to be aware of the project's problems and have enough information to guide the team and improve the project's chances of success. We published a survey to collect data for this study and validated the model by applying it to scenarios. The results obtained so far show that the model is promising.

Change decisions in product Development Projects
International Journal of Project Management, 2007Co-Authors: Wolfgang Steffens, Miia Martinsuo, Karlos ArttoAbstract:Abstract In dynamic business environments, product Development Projects rarely proceed according to the original plan. It is likely that some changes must be made and plans or goals be redefined to adapt to changes in the business environment. Which changes should the project approve and implement, which ones to reject, and why? Earlier product Development literature has largely covered planned decisions and go/no-go decision criteria in line with a phased product Development process. Project management literature, in turn, suggests change management processes and practices during the project. Earlier research has not sufficiently covered criteria for change decisions that are needed between product Development gates, nor a holistic approach for making such decisions in complex product Development Projects. This paper explores decision criteria and change management in complex product Development Projects. In a qualitative, multiple-case setting we characterize change management practices, decision criteria, and managers’ experiences with change management in seven complex product Development Projects within one firm. The results report multiple parallel change management approaches differing in terms of business context maturity, type of change, and IT system use. Operative criteria dominated in the change decisions of the case Projects, as opposed to more long-term oriented strategic criteria. The paper concludes with propositions concerning more holistic change management frameworks that would account for contextual contingencies.

problems in managing internal Development Projects in multi project environments
International Journal of Project Management, 2003Co-Authors: Suvi Elonen, Karlos ArttoAbstract:Abstract This article identifies problems in managing multiple internal Development Projects. The research methodology employed organisation-specific interviews, surveys and workshops on two case project portfolios. Project portfolio management studies provide one view on existing knowledge in this area. The study results in six relevant problem areas: (1) Inadequate project level activities, (2) Lacking resources, competencies and methods, (3) Lacking commitment, unclear roles and responsibilities, (4) Inadequate portfolio level activities (5) Inadequate information management and (6) Inadequate management of project-oriented organisation. The article suggests further analysis and Development of managerial practices on these areas.

Valuing Research and Development Projects in Energy Markets
Valuing Corporate Innovation, 2018Co-Authors: Peter SchäferAbstract:In this chapter we highlight the importance of appropriately valuing research and Development investments. We identify specific characteristics of research and Development Projectsresearch and Development Projects, such as irreversibility, uncertainty and managerial flexibilitymanagerial flexibility. In Sect. 2.2 we suggest valuation tools that are able to take these characteristics into account in order to valuate Projects in research and Development. In Sect. 2.3 we present a case study. The case study analyzes the decision process in the Development of the Siemens H-class Gas TurbineSiemens H-class Gas Turbine. It illustrates how companies make their decisions about research and Development Projects in practice.

a fuzzy robustness measure for the scheduling of commissioned product Development Projects
Fuzzy Sets and Systems, 2019Co-Authors: Matthias Wichmann, Maren Gade, Thomas SpenglerAbstract:Abstract Due to a considerable degree of uncertainty, the generation of robust schedules for the execution of product Development Projects is a crucial planning task. In the area of robust project scheduling, one basic option is to apply surrogate robustness measures as estimates of schedule robustness. Although project managers typically possess vague information about activity variations, most surrogate measures neglect this knowledge and are entirely based on deterministic data. In this contribution, we therefore present the “fuzzy overlap”, that is, to the best of our knowledge, the first surrogate robustness measure for schedule stability which accounts for fuzzy activity duration. We provide a mathematical formulation and embed the fuzzy overlap in a two-stage planning approach for the scheduling of product Development Projects, which aims at balancing the minimization of project costs as the basic scheduling objective with the maximization of schedule robustness. In a numerical study, we compare the performance of our proposed approach with comparable deterministic surrogate robustness measures. The results indicate that the consideration of fuzzy information enhances schedule robustness compared to the application of traditional deterministic surrogate robustness measures.
