The Effects of Information Overload on Software Project Risk Assessment*

Managers are responsible for providing effective information technology governance of the software development process. Ineffective governance leads to serious resource misallocations and negative consequences concerning Sarbanes‐Oxley compliance. In order for managers to make informed decisions about software development projects, they often need more information than is available through normal information channels, that is, they need an in‐depth review of the at‐risk project. Such in‐depth reviews, however, are costly. Hence, accurate identification of at‐risk projects for in‐depth review is critical to management's ability to govern. This research considers how two factors, information load and time pressure, affect the quality of the project‐selection process. We examine quality by observing the decision strategies involved and then relating these strategies to subsequent decision making. An experiment was conducted with experienced information systems auditors using a combination of policy‐capturing and computerized process‐tracing techniques. The participants in our study cope with information overload by accelerating their decision‐making process and adopting noncompensatory decision processes. Contrary to prior research, our process‐tracing analysis suggests that participants rarely filter information, thus implying that decision makers are unable to process all the information. Coping by resorting to noncompensatory strategies did not decrease decision quality unless combined with accelerated information processing. Participants also increase their weight on the software project risk factors that they repeatedly access and that they view for longer periods of time. The theoretical contributions and practical implications regarding what actions managers can take to reduce the negative impact of information overload are discussed.     

Managing Outsourced Software Projects: An Analysis of Project Performance and Customer Satisfaction

We examine the drivers of project performance and customer satisfaction in outsourced software projects using a proprietary panel dataset. The data cover 822 customer observations related to 182 unique projects executed by an India‐based software services vendor. Adopting a multidisciplinary perspective, we investigate how project planning, team stability, and communication effectiveness impact project performance and customer satisfaction. We delineate the direct and interactive influences of the antecedent variables. We also examine how these influences are moderated by two important project contexts: (a) the nature of software work (maintenance and development vs. testing projects) and (b) project maturity (new vs. mature projects). Among other results, we demonstrate that, when project planning capabilities are high, the positive impact of team stability and communication effectiveness on project performance is even higher. In addition, our results suggest that the impact of communication on project performance is muted when team stability is high. Finally, we also demonstrate that the impact of the antecedent variables on project performance varies with the nature of software work. Our findings offer specific and actionable insights to managers that can help them manage outsourced projects better, and open up new research perspectives in the context of outsourced project management.

Linking Objectives to Actions: A Decision Support Approach Based on Cause–Effect Linkages

The process of translating objectives into actions is a difficult task. This difficulty is due to the wide range of possibilities and the lack of structured information. Managers must take into account relevant information and generate a range of options before a decision is reached. So far, little is available to guide managers in translating a set of objectives into actions. This paper presents a three‐stage action‐planning process to address this gap. The process, supported by a software tool, takes managers through the stages of model building, action generation, and action evaluation and selection. A case study illustrates the application of the process. The paper concludes by discussing the implication of this work for managers and academics.     

CIM implementation for job-shop environments

Abstract

Abstract. The small to medium-sized job-shop manufacturing industry can benefit most from the implementation of computer integrated manufacturing (CIM) technology, to meet the increasing demand for high-quality and economically priced products. The injection mould making industry is a typical representative for this group, where a manufacturer would generally produce moulds which consist of parts that are standard to every mould type or very similar. Thus, manufacturing techniques, such as group technology (GT), and production planning and control (information) management systems could make significant contributions in improving the efficiency of design and production operations.

The objective of the project, presented in this paper, was the development of a GT-based classification and coding (C/C) system for injection mould parts especially for the design and process planning phases, and the development of a production planning and shop-floor control (SFC) information management system.

An extensive investigation was carried out on existing GT-based C/C systems. This investigation, followed by a thorough examination of many injection mould parts for determining geometric similarities, led to the development of part families (classes) required for GT implementation. An OPITZ-type GT system was developed, thereafter, for the C/C of the manufactured parts of the target company.

The production planning and control software that has been developed for the target company utilizes a relational data base management system. It consists of 13 application programs, which provide a tool of organizing information for efficient production planning and SFC. The programs are designed to cover all manufacturing operations of a job from the proposal to the final testing stage. Shop orders and dispatch lists are created using this software for effective and prioritized SFC. Shop status and job status reports are generated based on feedback information received through time card entries.     

The Role of Contracts on Quality and Returns to Quality in Offshore Software Development Outsourcing

In this study, we examine how the different incentive structures inherent in two primary contract types—time and materials (T&M) and fixed price (FP)—influence the quality provided by the vendor in the software development outsourcing industry. We argue that the incentive structure of FP contracts motivates a vendor to be more efficient in the software development process, which results in higher quality as compared to projects executed under a T&M contract. We thus argue that vendors consistently staff FP projects with better trained personnel because they face the most risk on these contracts, resulting in better outcomes on these projects. We extend our analysis to propose that providing higher quality is associated with higher profit margins for the vendor only for FP contracts. We develop and test these hypotheses on data collected from 100 software projects completed by a leading Indian offshore vendor. The results provide strong support for our fundamental thesis that the drivers of and returns to quality vary by contract type. We discuss the implications of our research for both researchers and practitioners.     

Developing strategic thinking

This paper looks at the problem of getting managers to contribute effectively to strategic planning, and focuses on the role of management development approaches in ensuring that this happens. A number of formal, and less formal, management development techniques are discussed in the light of their relevance for developing strategic awareness. The importance of providing exposure to strategic issues at an early stage in managers' careers is stressed, and also the need to encourage managers to take initiatives in obtaining their own development. Some of the most fruitful techniques involve taking full advantage of the ‘natural learning’ that takes place on the job, and those which provide a close integration between management development and the planning process—such as projects and ‘task forces’. Finally the role of senior managers in helping to create and maintain a climate in which strategic abilities can develop is discussed.     

Allocation of research and development funds: A zero-one goal programming approach

The research and development project selection process is one of the most difficult and important problems faced by management. It is typically complicated by indivisibility of projects and multiple and conflicting objectives, in addition to limitations on funding, facilities, and qualified researchers. In this paper a case example involving a high technology electrical equipment manufacturer is developed to illustrate this problem using zero—one goal programming to accommodate indivisibility of projects in addition to multiple and conflicting goals. The model presented is an attempt to provide managers with a robust tool for allocating scarce resources among research and development projects.     

Is your information system mature enough for computerized planning?

This paper presents the results of a study of computerized planning models in 235 firms throughout the world. The authors argue that organizational climate can be a serious pitfall to the inplementation of long-range planning systems. However, their view of climate extends beyond the traditional behavioral domain to include the sophistication of the organization's information system. The paper addresses itself to one of the key questions affecting the implementation of long-range planning systems. Why do some organizations develop computerized planning models and others do not?

Task partitioning in new product development teams: A knowledge and learning perspective

R&D alliances and outsourcing elements of the new product development process are now commonplace practices among many firms. However, little previous work has examined how these organizational choices influence project knowledge and learning. Based on a comparison of three new product development projects in the software industry, this paper examines how task partitioning in the project influences learning and knowledge development within the firm. The paper suggests that internal development projects encourage synthetic learning and development of architectural and tacit knowledge; in contrast, outsourcing and joint ventures encourage analytic learning and development of component and explicit knowledge.     

Scenarios,Real Options and Integrated Risk Management

In the 1970s, scenario planning gained prominence as a strategic management tool. Scenario planning encourages managers to envision plausible future states of the world and consider how to take advantage of opportunities and avoid potential threats. In the last decade, finance researchers have developed real option analysis as a way to value investments under uncertainty. Scenario planning and real option analysis have complementary strengths and weaknesses as tools for managers making strategic investment decisions under uncertainty. We combine these two approaches in an integrated risk management process. This process involves scenario development, exposure identification, formulating risk management responses, and implementation steps. We advocate a corporate-level perspective on managing risk that takes into consideration the full range of exposures across a firm’s portfolio of businesses. In contrast with the predominant emphasis on quantitative analysis in the real option literature, this study illustrates qualitative assessment of real options.     

受弹性时间段和价值波动双重影响的项目组合选择问题研究

许多现有的项目组合模型都认为项目集合可以在固定的计划期完成,但是在实际的项目执行过程中,决策者为了使得高收益的项目纳入项目集合中或者放弃风险高的项目来释放更多的资金,会选择对项目组合固定的计划期进行灵活性调整。同时,考虑到项目未来价值的不确定性,本文利用实物期权的二叉树模型给出了价值波动的公式,进而建立了同时受弹性时间段和价值波动影响的项目组合选择的新模型,对传统的计算项目价值的净现值法进行补充。通过GAMS/BARON对算例进行求解,验证了模型的合理性和有效性。结果表明：考虑弹性时间段和价值波动的影响会给更符合企业长期的发展战略,给企业带来更大的收益,该模型也为处理不确定情况下的项目组合问题提供了新思路和新方法。     

Modelling collaborative product development using axiomatic design principles: application to software industry

Even though collaborative product development (CPD) is considered as a strategic business plan to maintain competitive advantage, the literature lacks a systematic and detailed model of CPD from a strategic point of view. This article aims to develop a CPD model based on an axiomatic design technique by offering a system perspective in the context of software development (SD). Software industry is characterised by a dynamic and innovative nature and it gives a suitable application area in order to detail the proposed model in industry. Three main dimensions of CPD derived from the literature are defined in strategic level: partnership process, collaboration process and PD/SD. These three dimensions are detailed into hierarchy through business feedback and by experts from software industry. The model is evaluated and verified through two interviews. A case study is then conducted to observe the performance of the model. The conceptual model offers a guideline for CPD practitioners to increase effectiveness in collaborative efforts in the development process. The proposed model incorporates the main success factors of CPD in general, collaborative SD in specific, and it can be used as a performance evaluator in collaborative projects.     

Experimental earliness/tardiness production planning with the due window system

In order to use the philosophy of JIT to improve the production planning method of MRP-II, we propose the experimental software system of the earliness/tardiness produc tion planning problem with due window. By means of the approaches and model reported in this paper, the optimal production planning can be achieved. The recommended model extends the problem of due window from the shop scheduling level into the aggregated planning level of mass manufacturing systems. Simulation results have demonstrated that the experimental software is a useful tool for the production management of repetitive manufacturing enterprises.     

From organization development to corporate development at Trebor

This article is a case history of a medium-sized, family-owned business where the corporate planning activity has been taken over by the Executive Board, which is concerned with a careful definition and dissemination of company strategy and with focusing action in the form of long-term planning projects. The organizational learning approach is evolutionary and incremental, involving—as in the Japanese style of management— many levels in project development.     

Managing uncertainty and ambiguity in frontier R&D projects: A Korean case study

One of the important tasks in planning large, frontier R&D projects is to minimize innate uncertainties and ambiguities in the early stages of the project. This case study is an attempt to provide a framework to handle such problems in R&D planning. In it we analyze various elements that define planning conditions, classify them into basic constructs, and suggest tools and methods to deal with uncertainty and ambiguity. We utilize two case studies to approach the research questions. Our findings suggest that both initial planning conditions and the effectiveness of front-end planning management affect the performance of R&D planning and the later R&D process.     

Technological newness: An empirical study in the process industries

Technological change in product development is a crucial issue in the management of technology. The entire sweep of technological changes over the past hundred of years is, in essence, the sum of thousands of individual product development projects in thousands of firms. Yet the degree of technological change in individual development projects has not been extensively studied. This paper presents a four-dimensional characterization of technological newness for product development projects in the process industries in which product development is closely tied to process innovation. The characterization uses four dimensions of change that are required in the development of new products: chemistry, production equipment, fabrication technology and process control. Based on the framework of technological newness, the paper presents data collected on the degree of process change in a set of 20 product development projects conducted by a large manufacturer of advanced polymers. The data provide a clear demonstration of the value of the measurement framework, showing a strong relationship between the characterization of change and the project performance.     

Linear programming techniques in R & D project planning

In a multi-project industrial R & D organization the selection of projects with potentially good payoffs has to be fitted in with the planning of on-going projects as they compete for the same expert staff, laboratory equipment, pilot plant rigs and other facilities and resources. A linear programming approach to this planning problem takes account of any flexibility possible in allocating resources to projects, and in their timing in finding the ‘best’ plan. This is the one which maximises the potential payoff for the whole ‘portfolio’ of projects and makes the most efficient use of the available resources. The principles of the formulation of such LP models and the interpretation of the results produced in terms of practical planning are discussed.
