Problem‐formulation and problem‐solving in self‐organized communities: How modes of communication shape project behaviors in the free open‐source software community

Research summary: Building on the problem‐solving perspective, we study behaviors related to projects and the communication‐based antecedents of such behaviors in the free open‐source software (FOSS) community. We examine two kinds of problem/project‐behaviors: Individuals can set up projects around the formulation of new problems or join existing projects and define and/or work on subproblems within an existing problem. The choice between these two behaviors is influenced by the mode of communication. A communication mode with little a priori structure is the best mode for communicating about new problems (i.e., formulating a problem); empirically, it is associated with project launching behaviors. In contrast, more structured communication fits subproblems better and is related to project joining behaviors. Our hypotheses derive support from data from the FOSS community. Managerial summary: We study how the way in which individuals communicate influence the project‐behaviors they engage in. We find that relatively unstructured communication is associated with the setting up new projects, while communication that is structured around an artifact is associated with joining projects. Our findings hold implications for understanding how management may influence project behaviors and problem‐solving: Firms that need to concentrate on more incremental problem‐solving efforts (e.g., because a sufficient number of attractive problems have already been defined) should create environments in which interaction is undertaken mainly via artifacts. On the other hand, if firms seek to generate new problems (e.g., new strategic opportunities), they should create environments in which open‐ended, verbal conversation is relatively more important than artifact‐based communication.

Ambiguous workarounds in policy piloting in the NHS: Tensions,trade‐offs and legacies of organisational change projects

Pilot projects are increasingly used as a mechanism to enact organisational change, particularly government policy. Information technology's centrality to organisations often makes it key to the introduction of new processes. However, it can give rise to workarounds as employees circumvent impediments it presents by rejecting its prescribed use. Workarounds tend to be conceptualised dichotomously, as either ‘good’ problem solving, or ‘bad’ subversion of the technology. In pilot projects, workarounds are more ambiguous because those that support projects' successful completion in the short‐term may undermine day to day operations longer term. We draw on interview data from a policy pilot in general practice in the National Health Service in England aimed at extending access to care. We problematise the dichotomous conceptualisation of workarounds, finding they can be simultaneously supportive and undermining of policy pilots. Workarounds thereby become political, as employees are required to trade‐off consequences for themselves and the wider organisation.     

Determinants and archetype users of open innovation

Extant research on open innovation (OI) offers no systematic insight of how and why firms differ regarding the extent to which they conduct OI activities. Whereas past theoretical contributions have focused on explaining the externalisation of R&D activities as a result of firm-external factors, we focus on explaining this externalisation as a result of firm-internal weaknesses, specifically, impediments to innovation. Using the exploration–exploitation dichotomy as our theoretical framework, we develop hypotheses on how impediments to innovation influence the breadth and depth of OI. We then test these hypotheses by using an exceptionally large and detailed data set to estimate population-averaged panel models. Our results provide support for most of the hypothesised relationships. Further, they allow to identify four 'archetypes' of firms that differ significantly regarding the breadth and depth of OI and the importance of impediments. Finally, we discuss the significance of these findings for both academics and managers.     

Impediments to sales force automation

Sales force automation (SFA) occurs when firms adopt technology to improve the efficiency and effectiveness of sales-related activities. Research has shown, however, that 55-75% of SFA projects fail. This paper first identifies and explains impediments that exist in three SFA areas: planning, communication, and evaluation. The high failure rate of SFA can also be explained by gaps that exist, between the sales force and management, in SFA perceptions and goals. Finally, after discussing each of these areas, study implications are provided to sales managers and suggestions are offered for future research.     

A unified solution approach for the due date assignment problem with tardy jobs

We analyze a number of due date assignment problems with the weighted number of tardy jobs objective and show that these problems can be solved in O(n²) time by dynamic programming. We show that the effects of learning or the effects of past-sequence-dependent setup times can be incorporated into the problem formulation at no additional computational cost. We also show that some single-machine due date assignment problems can be extended to an identical parallel machine setting. Finally, we improve the complexity of the solution algorithms for two other due date assignment problems.     

Project Ranking in Petroleum Exploration

Abstract

Project ranking based on project value is an essential management task for organizations that face resource bottlenecks. Project value focuses on the hard elements of projects that can be expressed in monetary terms. In the petroleum exploration business, however, there is also soft information, like effects on corporate liquidity, advantages of compliance with the strategic goals, or learning potential and organizational development, which may change the ranking hierarchy. The aim of this research is to provide a solution for incorporating industry-based selected soft data in the project ranking process. The process is illustrated with a case study. We took the structured system of criteria identified from the petroleum industry.

The importance of design thinking for technological literacy: a phenomenological perspective

“We know that progress depends on discovery, inventions, creativity and design, but we have simply supposed that it happens anyway,” de Bono (1999 p. 43). Technology education is ostensibly a foundation for future designers and creative thinking. However evidence of good design or creative thinking in outcomes displayed in school technology studios is limited. Technology is inextricably linked with applied science, but I argue that scientific method couldn’t be further from creativity and designing as technology education based on this premise can confine problem solving to a set of prescribed components that harness teachers to narrowly defined and deeply focused goals. This paper attempts to analyse the nature of this phenomenom, debate the place of creativity, imagination and personal sensitivities as part of designing and demonstrate that although there are inseperable links between design and technology the structure of a technology curriculum could be a barrier to opportunities for effective design thinking.     

A block mining and re-combination enhanced genetic algorithm for the permutation flowshop scheduling problem

The goal of block mining is to obtain a set of genes that contain dependency among gene relationships. Such blocks without overlapping of genes can be further merged to form a new chromosome and the quality of the new chromosome can be greatly improved. Based on this concept, we propose a novel block mining method that is able to locate common structures or to establish new blocks (like a small piece of puzzle) from a set of high fit chromosomes. The identified blocks (puzzles) will also be updated generation by generation through the newly updated high fit chromosomes. We develop a heuristic re-combination procedure to form a new chromosome by re-combining the blocks. We call the new chromosomes generated as artificial chromosomes (ACs) and inject them into the evolutionary process when the convergence slope of the evolutionary process is less than a predefined threshold. This new algorithm retains the regular simple genetic algorithm (SGA) operations of crossover and mutation, and utilizes the ACs generated from elites to speed up the convergence process. Experimental results indicate that the puzzle-based method of chromosome generation is very efficient and effective in solving the traditional permutation flowshop scheduling problem. The new method can be applied to tackle other NP-complete problems such as scheduling and vehicle routing problems.     

Post-Failure Success: Sensemaking in Problem Representation Reformulation

Failure is an inevitable feature of innovation, and management research promulgates the importance of learning from it. Key to excelling at an innovation-based strategy is understanding the processes that can turn failures into successes. However, post-failure success remains elusive. Although failure signals that the innovation journey is off course, shifting trajectory is difficult, because it may require revising assumptions and reformulating the project’s problem representation. Using comparative case studies, this study set out to understand how problem representations are reformulated. Employing case method and comparing data versus theory iteratively, the important role of sensemaking and of leadership behaviors in driving post-failure success became salient. Findings show that problem representations post-failure require a process of problem formulation characterized by sensemaking and that innovative solutions are enabled by the reformulation of problem representations that spring from prospective sensemaking. Furthermore, this article identifies leadership change behavior as the linchpin driving a problem formulation process characterized by prospective sensemaking that catalyzes innovative solutions and explains why some projects thrive post-failure and others do not. This article provides empirical support to the theoretical work of the literature on problem formulation, while extending the learning-from-failure literature by emphasizing and demonstrating the process driving post-failure success. The major implication of our study is that different leadership behaviors may foster different types of sensemaking (retrospective or prospective), and that, in turn, the type of sensemaking matters for how a problem is reformulated. Ultimately, this article concludes that in the context of project failure, problem reformulation that springs from prospective sensemaking enables innovative solutions post-failure.     

Realising the Potential – and Lost Opportunities – for Peer Collaboration in D&T Setting

This paper follows up our theoretical discussion of the potential for collaborative problem solving in Design and Technology (Hennessy and Murphy, 1999). In this paper we report our empirical investigation of peer collaboration in a setting where we identified the presence of significant pre-conditions for productive collaboration. The study investigated the participation of two boys aged 13 who worked together with their teacher over 8 weeks in designing and making an aid for a child with a disability. We analysed their participation using a framework of key features derived from the research literature. Our analyses yielded evidence of effective collaboration in the early design stage, but the students' collaboration and their progress were subsequently undermined. The reasons related to the students' ability to collaborate and the tension for the teacher between students' learning needs and client needs within an authentic activity. The outcome was a successful product but a wealth of lost opportunities – and lack of support – for the students' collaborative problem solving and Design and Technology (D&T) learning. Our observations confirm that despite little evidence of collaboration in D&T, this setting offers extensive resources for supporting collaboration in joint design, planning and problem-solving activities. We also identify impediments to collaboration as a learning mechanism. This revised version was published online in July 2006 with corrections to the Cover Date.     

Food and nutrition policy formulation: A Delphi approach to establishing basic principles

The authors describe the results of a multidisciplinary, international Delphi inquiry carried out to establish basic principles for food and nutrition policy formulation. A working vocabulary is established, preliminary assumptions are set up, and controversial topics are defined. The inquiry resulted in a consensus on several policy statements which can serve as guidelines in the development of flexible food and nutrition programmes.     

Ship routing problem with berthing time clash avoidance constraints

We consider a ship routing problem in which multiple vessels have to perform pickups and deliveries of cargoes at various locations. The loading and unloading time of cargoes at pickup and delivery locations is significant, and at each of these locations we need to assign a time slot to each vessel to perform the loading/unloading task so as to avoid time clashes. This problem is motivated by the operations of feeder vessels and company-owned cargo terminals, where the shipping company wishes to coordinate the routing and the berthing time of its vessels. We develop a heuristic algorithm for the problem using set partitioning formulation and column generation techniques. The effectiveness of the heuristic is tested via extensive computational experiments.

Cognitive flexibility and adaptive decision‐making: Evidence from a laboratory study of expert decision makers

Research Summary : How can strategic decision makers overcome inertia when dealing with change? In this article we argue that cognitive flexibility (i.e., the ability to match the type of cognitive processing with the type of problem at hand) enables decision makers to achieve significantly higher decision‐making performance. We show that superior decision‐making performance is associated with using semiautomatic Type 1 cognitive processes when faced with well‐structured problems, and more deliberative Type 2 processes when faced with ill‐structured problems. Our findings shed light on the individual‐level mechanism behind organizational adaptation and complement recent work on strategic inertia. In addition, our findings extend management studies that have stressed the relevance of cognitive flexibility for responding to the demands of increasingly open, flexible, and rapidly changing organizations. Managerial Summary : Humans are creatures of habits. We tend to prefer known courses of action over new ones. In many cases, habits are good. However, when things change in unpredictable ways, the past may not be good guidance for the future. We argue that “cognitive flexibility”—the ability of understanding when to rely on habits vs. when to explore new courses of action—enables managers to switch from a “fast” decision mode, based on habits, to a “slow,” more deliberate decision mode that facilitates the exploration of new courses of action. Managers high in cognitive flexibility reflect on the situation at hand, recognize and value diversity in viewpoints, and integrate such diversity in their own decision processes. By valuing diversity, they are more likely to overcome inertia.     

Growing pains: Pre‐entry experience and the challenge of transition to incumbency

We examine how entrepreneurial entry by diversifying and de novo firms in new industries leads to different levels of performance. We propose that these types of firms differ in dynamic capabilities, which help them overcome growth impediments and transition to incumbency in the industry. Growth impediments arise at larger size, older tenure levels in industry, and after technological discontinuities. Because of their prior experience, diversifying firms are better equipped to handle the challenges of impediments to growth. Meanwhile, de novo firms, ostensibly tailor‐made for the targeted industry, are more likely to stumble over these growth challenges, and eventually lag behind diversifying firms. We find support for our hypotheses using a near census of firms in the U.S. wireless telecommunications industry over the 1983–2004 period. Copyright © 2011 John Wiley & Sons, Ltd.     

THE EFFECT OF PROJECT RISK ON CAPITAL RATIONING UNDER UNCERTAINTY

The purpose of this paper is to investigate the effect of project risk on capital rationing with uncertain budgetary constraints. We reflect project risk by the standard deviation of cash flows. The problem is formulated in a stochastic linear programming with simple recourse (SLPSR) framework. In a sample problem, we vary the level of project risk and allow the probability distribution for the right-hand side constraints to be either symmetric or left skewed. We demonstrate that SLPSR yields superior solutions to an equivalent deterministic formulation and that risk aside, the borrowing rate is an important factor in determining the optimal solution vector. Moreover, we show that low project risk can compensate for higher borrowing costs and that the presence or absence of probability distribution asymmetry may not be an important issue.     

From Experience: The Corporate Black Hole

There is a lot of creative potential lying dormant in corporations because too many managers fail to see innovation as a process to be deliberately managed. C. Joshua Abend sees innovation connected to virtually everything that happens—or doesn't happen—in an organization. He offers in this article ideas that managers can use to remove the impediments to increased innovation and productivity.     

Metrics thermostat⋆

The explosion of information and information technology has led many firms to evolve a dispersed product development process with people and organizations spread throughout the world. To coordinate such dispersed processes a critical role of managers is to establish and foster a culture that implicitly rewards and motivates product development teams to perform against a set of strategic metrics such as customer satisfaction, time to market, defect reduction, or platform reuse. We focus on a practical method to fine‐tune a firm's relative emphasis on these metrics. In particular, we seek to advise a firm how to modify their emphasis on each metric in order to improve profits. We use a thermostat analogy based on an adaptive control feedback mechanism in which we estimate the incremental improvements in priorities that will increase profits. Iterations seek to maximize profits even if the environment is changing. In developing the metric thermostat we recognize that there are hundreds of detailed actions, such as the use of the house of quality and the use of robust design, among which the product development team must choose. We also recognize that team members will act in their own best interests to choose the actions that maximize their own implicit rewards as determined by the metrics. Management need not observe or dictate these detailed actions, but rather can control the process by establishing implicit weights on the metrics. The thermostat works by changing those implicit weights. We define the problem, introduce the adaptive control mechanism, modify “agency” theory to deal with incremental changes about an operating point, and derive methods that are practical and robust in light of the data that firms have available. Our methods include statistical estimation and internal surveys. The mathematics identify the critical few parameters that need be determined and highlight how to estimate them. Both the measures and the estimation are illustrated in an initial application to a large office‐equipment firm with $20 billion in revenue. The metrics thermostat suggests that this firm has about the right emphasis on time‐to‐market, but has overshot on platform reuse and has lost its focus on customer satisfaction. We describe how the firm reacted to the recommendations and changed its organization.
