Collaborative software development involving multiple organizational units, often spanning national, language, and cultural boundaries, raises new challenges and risks that can derail software development projects even when traditional risk factors are being controlled. This article presents a framework that can be used to manage collaborative software development projects, based on an extended set of risk management principles. Three risk factors — trust, culture, and collaborative communication — are discussed in depth. 相似文献

The classic models of two party problem solving in situations of potential conflict are reviewed and the growing impetus for a process that would encourage collaborative win‐win solutions is summarized. In is demonstrated that in‐win collaboration requires innovative thinking, and that a four stage process of deliberate creativity with a track record of success is described. The process, called Simplex, emphasizes ‘out of the box’ thinking in problem defining (before solving) as the key to making a perceived ‘fixed pie’ larger, moving beyond the shackles of zero‐sum, win‐lose, compromise thinking. If a problem can be conceptualized from a new angle in such a way that each party believes its resolution would provide a high level of satisfaction, then the parties will be more likely to work together collaboratively. This process uses four specific creative thinking skills. A case study is described in which the Simplex process was used in union management bargaining. In the case study, when the creative process was deliberately applied, success was achieved in building trust and developing expanded pies and new solutions. However, when the process was abandoned, the trust was lost, no creative solutions were developed, and a sub‐optimal lose‐lose situation resulted. A two‐dimensional diagnostic model which shows the relationship between skill level in the process and motivation to use it is provided. This model defines four modes of pure and mixed distributive and integrative bargaining. 相似文献

When solving a mathematical problem, we sometimes encounter a situation where we can not reach a correct answer in spite of acquiring knowledge and formula necessary for the solution. The reason can be attributed to the lack in metacognitive abilities. Metacognitive abilities consist of comparing the difficulty of problem with own ability, proper plan of solution process, and conscious monitoring and control of solution process. The role and importance of metacognitive ability in mathematical problem solving of permutations and combinations was explored. Participants were required to solve five practical problems related to permutations and combinations. For each problem, the solution process was divided into: (1) understanding (recognition) of mathematical problem; (2) plan of solution; (3) execution of solution. Participants were also required to rate the anticipation whether they could solve it or not, and to rate the confidence of their own answer. According to the total score of five problems, the participants were categorized into the group of the high test score and the group of the low test score. As a result, at the plan and the execution processes, statistically significant differences were detected between the high and the low score groups. As for the rating on the anticipation of result and the confidence of own answer, no significant differences were found between both groups. Moreover, the relationship between the score of plan process and the score of execution process was statistically correlated. In other words, the more proper the plan process was conducted, the more proper solution the participants reached. In such a way, the importance of metacognitive ability in the solving process, especially the plan ability, was suggested. 相似文献

Problem orientation is gaining interest as a way of approaching the development of software intensive systems, and yet, a significant example that explores its use is missing from the literature. In this paper, we present the basic elements of Problem Oriented Software Engineering (POSE), which aims at bringing both nonformal and formal aspects of software development together in a single framework. We provide an example of a detailed and systematic POSE development of a software problem: that of designing the controller for a package router. The problem is drawn from the literature, but the analysis presented here is new. The aim of the example is twofold: to illustrate the main aspects of POSE and how it supports software engineering design and to demonstrate how a nontrivial problem can be dealt with by the approach. 相似文献

Human–computer collaboration is extremely necessary for solving ill-structured problems and critic systems can effectively facilitate human–computer collaborative problem solving. This paper conducts a systematic study on critic systems. First, the concepts of critic systems are presented. Then, a literature review is presented on critic systems. Afterwards, a generic architecture is put forward for critic systems, with its important aspects being analyzed. Finally, two case studies are given to illustrate critic systems. 相似文献

Software development is rarely an individual effort and generally involves teams of developers collaborating to generate good reliable code. Among the software code there exist technical dependencies that arise from software components using services from other components. The different ways of assigning the design, development, and testing of these software modules to people can cause various coordination problems among them. We claim that the collaboration of the developers, designers and testers must be related to and governed by the technical task structure. These collaboration practices are handled in what we call Socio-Technical Patterns.
The TESNA project (Technical Social Network Analysis) we report on in this paper addresses this issue. We propose a method and a tool that a project manager can use in order to detect the socio-technical coordination problems. We test the method and tool in a case study of a small and innovative software product company. 相似文献

The last decade progresses have led the Satisfiability Problem (sat) to be a great and competitive practical approach to solve a wide range of industrial and academic problems. Thanks to these
progresses, the size and difficulty of the sat instances has grown significantly. Among the recent solvers, a few are parallel and most of them use the message passing
paradigm. In a previous work by Vander-Swalmen et al. (IWOMP, 146–157, 2008), we presented a fine grain parallel sat solver designed for shared memory using OpenMP and named mtss, for Multi Threaded Sat Solver. mtss extends the “guiding path” notion and uses a collaborative approach where a rich thread is in charge of the search-tree evaluation and where a set of poor threads yield logical or heuristics information to simplify the rich task. In this paper, we extend the poor thread abilities
of mtss and present extensive comparative results on random 3-sat problems. These new experimentations show that fine grained techniques associated to poor tasks within the framework of mtss can achieve very interesting speedup on multi-core processors. 相似文献

We present a new model for parallel evaluation of logic programs. This model can exploit the main sources of parallelism that the language of logic expresses: Independent AND parallelism and OR parallelism, together with a secondary source emerging as a consequence of the Independent AND Parallelism: the producer/consumer parallelism. The efficiency is derived from the use of ordered structures for managing the information generated throughout the search process. The model is suitable for evaluating programs with a high degree of non-determinism because it never generates two processes for solving the same subgoal and hence it can exploit the same real parallelism generating a lower number of processes than other models. As an application example, we consider the Job Shop Scheduling problem. We report experimental results showing that logic programs can be designed that exhibit parallelism, and that the use of heuristic information translates into speedup in obtaining answers. 相似文献

. This paper describes a prototype implementation of a software platform that enables the utilization and collaborative development
of structural analysis programs, taking advantage of the Internet and web-based technologies. The new platform would allow
users to have easy access to the structural analysis platform via the Internet. Users can have direct access to the analysis
program and the analysis results by using a web-browser or other application programs, such as MATLAB. Furthermore, the platform
is intended to serve as a common finite element structural analysis tool for which researchers and users can build, test,
and incorporate new developments. Researchers and developers can link the analysis platform with their developments by utilizing
pre-defined Internet-enabled communication interfaces. The prototype system is applied to perform a nonlinear dynamic analysis
for a two-dimensional frame structure. It is shown that the Internet-enabled collaborative paradigm can potentially provide
greater flexibility and extendibility than traditional structural analysis programs, which are typically packaged individually. 相似文献

Managing software development is getting harder. Expensive before off-shoring, it has now become expensive even in offshore countries. The clamor for more H-1 visas in the US would have us believe the country has a dearth of software professionals. Is it really a shortage of resources or a misuse of them? This paper discusses what is exactly the problem in software development. 相似文献
