Bringing IT Back: An Analysis of the Decision to Backsource or Switch Vendors

Whereas the decision to outsource information systems (IS) has been an important focus in IS research and practice, the decision to switch vendors or to backsource has received little attention. Evidence suggests that in practice, however, the decision to backsource or to switch vendors is becoming increasingly common as firms vie for ways to continue to cut information technology (IT) costs and improve IT service levels. This research specifically examines the factors associated with the decision to backsource or to switch vendors. Based on a sample of 160 IT managers involved with application development, we compare and contrast the perceptions of those who switched vendors, backsourced, or continued in an outsourcing relationship for application development. Our findings suggest that product quality, service quality, relationship quality, and switching costs are related to the decision to backsource application outsourcing. However, service and product quality did not influence the decision to switch vendors. Rather, firms that made the decision to switch vendors reported high levels of service and product quality but low levels of relationship quality and switching costs.     

Real option games with R&D and learning spillovers

We demonstrate to decision makers how to optimally make costly strategic pre-investment R&D decisions in the presence of spillover effects in an option pricing framework with analytic tractability. Decisions are modeled as impulse-type controls with random outcome. Two firms face two decisions that are solved interdependently in a two-stage game. The first-stage decision is: What is the optimal level of coordination (optimal policy/technology choice)? The second-stage decision is: What is the optimal effort for a given level of the spillover effects and the cost of information acquisition? The framework is extended to a two-period closed-loop stochastic game with (path-dependency inducing) switching costs that make strategy revisions harder. When conditions of learning-by-doing exist, we find that strategy shifts are easier to observe in market environments of high growth and high volatility.     

Validating measures of information technology outsourcing risk factors

Outsourcing information technology (IT) operations has been recognized to have important potential benefits, including cost reduction, improved quality of service, and access to technological expertise. Researchers and practitioners also recognize that, in some circumstances, IT outsourcing entails risk, and that it sometimes leads to undesirable consequences that are the opposite of the expected benefits. The main purpose of this study was to validate measures of the risk factors associated with outsourcing IT operations. Insights from transaction costs theory suggest that there exist three major sources of risk factors for IT outsourcing: the transaction, the client and the supplier. From these insights, preliminary measures of IT outsourcing risk factors were developed and data from a survey of 132 IT executives were analyzed with partial least squares to assess their reliability and validity. The results confirm that these factors are useful indicators for assessing IT outsourcing risks.     

不确定条件下的IT外包时机选择问题研究

IT外包的业务环境、技术环境和需求的不确定性往往会引起IT服务成本的不确定性。针对IT服务成本的不确定性和IT外包投资的不可逆性,运用传统净现值方法和实物期权方法比较固定价格合同、成本加成定价合同和收益共享合同3种常见合同的外包临界值,分析3种合同下客户企业的等待价值,并讨论客户企业推迟外包情形时的等待时间。研究结果表明,实物期权方法得出的外包临界值高于净现值方法得出的外包临界值;等待价值随无风险利率的增大而减小,随漂移率、变动率的增大而增大;当漂移率与变动率平方的比值大于二分之一时,客户企业选择外包的期望等待时间受无风险利率、漂移率和变动率的影响,其他情形下客户企业的期望等待时间不受无风险利率、漂移率和变动率的影响。研究结论为不确定条件下客户企业外包与否和外包时机的选择提供理论支持和实践指导。     

Outsourcing to a Powerful Contract Manufacturer: The Effect of Learning‐by‐Doing

The contract manufacturing industry has grown rapidly in recent years as firms have increasingly outsourced production to reduce costs. This growth has created powerful contract manufacturers (CMs) in several industries. Achieving a competitive cost position is often a primary motive for outsourcing. Outsourcing influences both the original equipment manufacturer's (OEM) and the CM's production levels, and, therefore, through learning‐by‐doing renders future costs dependent on past outsourcing decisions. As such, outsourcing should not be viewed as a static decision that, once made, is not revisited. We address these considerations by analyzing a two‐period game between an OEM and a powerful CM wherein both firms can reduce their production costs through learning‐by‐doing. We find that partial outsourcing, wherein the OEM simultaneously outsources and produces in‐house, can be an optimal strategy. Also, we find that the OEM's outsourcing strategy may be dynamic—i.e., change from period to period. In addition, we find both that the OEM may engage in production for leverage (i.e., produce internally when at a cost disadvantage) and that the CM may engage in low balling. These and other findings in this paper demonstrate the importance of considering learning, the power of the CM, and future periods when making outsourcing decisions.     

Information Technology in Public Services: Towards the Contractual Organization?

The growing trend towards information technology (IT) outsourcing is analysed within the UK public sector. The paper first details the research findings on factors influencing the degree of success experienced in a range of IT outsourcing deals. These factors are then utilized as a framework for analysing and discussing two case histories—of selective and large-scale IT outsourcing—drawn from different parts of the public sector. Both demonstrate how distinctive public-sector contexts influence the direction and degree of outsourcing. At the same time they highlight a range of managerial and organizational issues raised by moves towards contractual, core competence forms of organizing. Selective outsourcing is revealed as effective provided key decisions and actions are taken. The large-scale outsourcing case raises a number of critical issues not just for how it can be conducted in public-sector contexts, but also about the efficacy of such arrangements in terms of cost savings, possible over-dependence on a few suppliers, and ability to respond flexibly to changing political requirements and legislation.     

两寡头序贯进入下的B2B电子商务网站IT投资决策

在竞争性的B2B电子商务网站这一市场中,用户转移成本及网络外部性的存在会阻碍用户转向市场后入者,从而给市场先入者带来用户规模优势,而IT成本下降可以给后入者带来成本优势,在这些因素交互影响的市场环境下,先入者和后入者应采取何种IT投资策略以保持竞争优势是一重要问题。针对上述问题,通过综合考虑IT成本下降、用户转移成本及网络外部性等因素,构建了一个序贯进入的、两寡头垄断的B2B电子商务网站的IT投资决策模型,探讨了IT成本下降、用户转移成本及网络外部性等参数变化对B2B电子商务网站IT投资决策的影响。研究结果表明,随着IT成本下降,当用户具有高转移成本时,先入者可采取进攻性的、增加投资的策略;反之,当用户具有低转移成本时,后入者则可采取进攻性的、增加投资的策略,并且能够提供更高质量的网站,获得相对于先入者更高的市场份额;当网络外部性增强时,先入者则可采取进攻性的、增加投资的策略,而后入者只能采取防守性的、减少投资的策略。     

THE EFFECT OF LEARNING ON THE MAKE/BUY DECISION

By including the effects of learning over time on both the production of components and their integration into complete products, we develop an engineering‐based model of outsourcing. This model provides an alternative explanation for much of what other outsourcing theories predict, as well as making several new predictions. In particular, we show that outsourcing decisions can create a path‐dependent outsourcing trap in which a firm experiences higher long‐run costs after an immediate cost benefit. We also describe conditions under which outsourcing a small fraction of component production may dominate either complete insourcing or complete outsourcing. Finally, we show that, with discounting, there is a convex, curvilinear relationship between the optimal outsourcing fraction and the rate of technological change.     

基于疏忽的最优投资决策

The Influence of Cost and Quality Priorities on the Propensity to Outsource Production*

Outsourcing of production has escalated over the past decade due to unprecedented competition and worldwide access to low‐cost labor markets. This article examines how cost and quality priorities—two key attributes of manufacturing strategy—influence a manufacturer's propensity to outsource. By doing so, we bridge the existing gap between research on manufacturing strategy and firm boundaries. We develop a theory‐based model that links a manufacturer's cost and quality priorities to its plans to outsource production. Our empirical analyses, based on survey data obtained from 867 manufacturing business units, control for firm‐specific factors previously shown to impact outsourcing, including asset specificity, uncertainty, and current capabilities in cost and quality. We found that the competitive priority placed on cost played an integral role in sourcing decisions, while, surprisingly, conformance quality priorities did not. The cost result is consistent with our expectations and observations in practice. The significant effect of cost priority on outsourcing shows that any theory of firm boundaries that fails to consider competitive priorities is incomplete. The finding regarding quality, which was counter to our expectations, may partially explain why there is an emergence of so many nonconforming products associated with outsourcing. Taken together, our results provide theoretical insights for future research into how manufacturing managers can improve their decision making on outsourcing production.     

Decision Making and the Price Setting Newsvendor: Experimental Evidence

We present an experimental study of the price‐setting newsvendor problem, which extends the traditional framework by allowing the decision maker to determine both the selling price and the order quantity of a given item. We compare behavior under this model with two benchmark conditions where subjects have a single decision to make (price or quantity). We observe that subjects deviate from the theoretical benchmarks when they are tasked with a single decision. They also exhibit anchoring behavior, where their anchor is the expected demand when quantity is the decision variable and is the initial inventory level when price is the decision variable. When decision makers set quantity and price concurrently, we observe no significant difference between the normative (i.e., expected profit‐maximizing) prices and the decision makers’ price choices. Quantity decisions move further from the normative benchmarks (compared to when subjects have a single decision to make) when the ratio of cost to price is less than half. When this ratio is reversed, there is no significant difference between order levels in single‐ and multi‐task settings. In the multidecision framework, we also observe a tendency to match orders and expected demand levels, which subjects can control using prices.     

多部件采购外包的两阶段均衡投标策略

本文考虑一个由单个制造商和多个供应商群体组成的供应链——该制造商需要采购多个部件,对于每个部件在市场上均存在多个供应商。不同于传统的从各供应商群体分别采购各个部件,制造商考虑将所有部件的采购整体外包给某个供应商。在第一阶段,制造商使用一级价格密封投标的逆向拍卖来确定赢得整体采购合约的供应商。接下来,第一阶段投标的获胜者生产其所能供应的部件,并使用逆向拍卖向第一阶段中未获胜的其他竞标者采购其余部件。我们分析了供应商在两个阶段的均衡竞价策略,并比较了制造商在亲自逐件采购和外包整体采购两种情况下的期望采购成本。我们证明了在两种机制下制造商的总的期望采购成本相等。     

Sourcing Decisions with Competitive Suppliers and Imperfect Information

Manufacturers often must choose between outsourcing and producing internally. This choice is complex and influenced by a variety of factors, including the costs and capabilities of the potential suppliers. In addition, if the manufacturer outsources, he must design the sourcing process. We study the manufacturer's outsourcing decision, with a focus on the impact of the sourcing process on that decision. We consider a setting in which the manufacturer has imperfect information regarding the suppliers' costs and capabilities, and we assume that the manufacturer uses a two‐stage sourcing process. The first stage is the qualification stage, in which the manufacturer seeks to reduce the uncertainty regarding the suppliers' capabilities. The second stage is the supplier selection stage, in which the manufacturer selects among the qualified suppliers on the basis of price. We first characterize the optimal design of the two‐stage process, and then consider the outsourcing decision. We demonstrate several trade‐offs. Vertical integration enables the manufacturer to reduce uncertainty and extract all of the profits of production. However, outsourcing enables the manufacturer to take advantage of the (potentially) lower costs and higher capabilities of the suppliers, particularly if competition between suppliers can be encouraged. We find that the manufacturer is more likely to vertically integrate when the warranty cost and the cost of exerting effort during qualification are large, and when there is significant uncertainty regarding the suppliers' capabilities. The manufacturer is more likely to outsource when the suppliers' costs (capabilities) are low (high), and when the number of suppliers is large.     

Reasoned Decision Making Without Math? Adaptability and Robustness in Response to Surprise

Many real‐world planning and decision problems are far too uncertain, too variable, and too complicated to support realistic mathematical models. Nonetheless, we explain the usefulness, in these situations, of qualitative insights from mathematical decision theory. We demonstrate the integration of info‐gap robustness in decision problems in which surprise and ignorance are predominant and where personal and collective psychological factors are critical. We present practical guidelines for employing adaptable‐choice strategies as a proxy for robustness against uncertainty. These guidelines include being prepared for more surprises than we intuitively expect, retaining sufficiently many options to avoid premature closure and conflicts among preferences, and prioritizing outcomes that are steerable, whose consequences are observable, and that do not entail sunk costs, resource depletion, or high transition costs. We illustrate these concepts and guidelines with the example of the medical management of the 2003 SARS outbreak in Vietnam.     

Rationality in Strategic Information Technology Decisions: The Impact of Shared Domain Knowledge and IT Unit Structure*

Rationality is a fundamental concept to several models of IT planning and implementation. Though the importance of following rational processes in making strategic IT decisions is well acknowledged, there is not much understanding on why discrepancies occur in the IT decision‐making process and what factors affect rationality. Drawing upon structural and resource‐based perspectives of strategy, this study examines the influence of shared domain knowledge and IT unit structure on rationality in strategic IT decisions. Data were gathered from 223 senior IT executives using a survey to examine the relationships among the research constructs. The results suggest a positive impact of shared domain knowledge and formalization of IT unit structure on rationality in strategic IT decisions. Further, a highly centralized IT unit structure was found to negatively influence shared domain knowledge. On the other hand, formalization of IT structure positively influenced shared domain knowledge. The implications of the findings for research and practice are presented.     

Approaches to displaying information to assist decisions under uncertainty

The estimation of the costs of a product or project and the decisions based on these forecasts are subject to much uncertainty relating to factors like unknown future developments. This has been addressed repeatedly in research studies focusing on different aspects of uncertainty; unfortunately, this interest has not yet been adopted in practice. One reason can be found in the inadequate representation of uncertainty. This paper introduces an experiment, which engages different approaches to displaying cost forecasting information to gauge the consideration of uncertainty in the subsequent decision-making process. Three different approaches of displaying cost-forecasting information including the uncertainty involved in the data were tested, namely a three point trend forecast, a bar chart, and a FAN-diagram. Furthermore, the effects of using different levels of contextual information about the decision problem were examined. The results show that decision makers tend to simplify the level of uncertainty from a possible range of future outcomes to the limited form of a point estimate. Furthermore, the contextual information made the participants more aware of uncertainty. In addition, the fan-diagram prompted 75.0% of the participants to consider uncertainty even if they had not used this type of diagram before; it was therefore identified as the most suitable method of graphical information display for encouraging decision makers to consider the uncertainty in cost forecasting.     

Do service-oriented IT architectures facilitate business process outsourcing?

How does a firm’s IT architecture affect its potential to outsource business processes? As Information Technology (IT) has become many firms’ essential operational infrastructure or “backbone”, we are interested in scrutinizing to what extent the kind of IT architecture affects a firm’s boundaries or the plasticity of its boundaries. Focusing on the particular concept of service-oriented architectures (SOA), we concretely ask: How does SOA affect business process outsourcing potentials? Since SOA is widely expected to modularize the IT implementation of business processes, it should increase business process outsourcing (BPO) in terms of buying in the provision of single business functionalities. We develop and empirically evaluate a theoretical model that conceptualizes the relationship between SOA and BPO. Questionnaire data from 115 firms give first evidence that SOA facilitates BPO. By increasing IT modularity, SOA supports BPO by increasing sourcing flexibility and, in particular, operational benefits, while at the same time lowering financial risks and strategic risks, such as lock-in. Overall, however, firms see SOA-based BPO mainly in an operational context with low hidden costs and little strategic benefits.     

A review of outsourcing from the resource‐based view of the firm

The phenomenon of outsourcing is becoming increasingly widespread among organizations and is now one of the strategic decisions that attract the greatest interest from professionals and organizational scholars. The primary purpose of the paper is to contribute with a review of the principal works that address outsourcing from the resource‐based view of the firm (RBV). The paper begins by setting out the main premises of outsourcing and then presents the different concepts of outsourcing and proposes a concept that is more in line with the theoretical framework used. This is followed by an analysis of the principal differences and similarities of the treatments of outsourcing from the traditional perspective of the transaction costs economics theory (TCE) and from the more strategic and up‐to‐date RBV. The next section contains a review of the most significant theoretical and empirical works on outsourcing that address outsourcing from the RBV. The contributions are classified into two categories, depending on the objectives: works that study the propensity to outsource and works that study the relationship between the outsourcing decision and organizational performance. Finally, a framework is proposed that is based on the resource and capability view with the aim of contributing to a better understanding of outsourcing and facilitating future empirical works from the RBV that are complementary and examine issues of greater interest that have been less developed in the literature to date.     

Regression models of behavior for managerial decision making

A principal problem in systems studies concerns the development of models that will be accepted and used by decision makers in organizations. Regression models derived from managers' past behavior offer promise in overcoming this problem for many repetitive types of decisions. Employing a simulated production planning environment, this paper discusses both the potential usefulness and limitations of such models for understanding and improving decision making in practical applications.
