The global business environment provides emergent business opportunities as well as challenges. To tap these opportunities and to respond to uncertainties in global business environments, firms must not only develop global business strategies but also support them with information systems aligned with these strategies. Such systems are increasingly being developed in globally distributed environments,especially in countries with availability of low-cost, advanced technical expertise.
There are two challenges in the development and deployment of globally distributed systems. First, from the development perspective, the complexities of coordination, communication, culture, and technology create challenges due to the disparate compositions of teams in dispersed geographic locations. Second, from the deployment perspective, firms need to cater to the specific local requirements of the sites spanning the activities of the global business. To address these challenges, firms must have the capability (that is, agility) to rapidly develop and deploy systems to meet emerging business needs.
While there is growing interest in agility for successful global system development, at present there are only a few studies that examine it in the context of globally distributed system development (GDSD) projects. The objective here is to provide a better understanding of the role of agility in developing and deploying GDSD to support diverse local business needs in the global scenario, and to explain how such agility can be achieved in the GDSD context.
Drawing from prior studies on agility, open source software (OSS) development, and IT resources, we identify three components of agility in GDSD projects: agile IT strategy, agile IT infrastructure, and agile IT project management. Also, drawing from the perspective of business/IT alignment, we suggest these components are interdependent, and the capability to derive synergy from the interaction of these three components in an iterative manner determines the extent of agility in GDSD projects. We present a framework depicting the concept of agility and provide supporting evidence for the framework with the case study of a successful GDSD project, a global business system development and deployment through a LEGO-like integration of multi-sourced, predesigned, existing financial service components with a component-based IT strategy [3].
Agility in GDSD Projects
Business agility is defined as a firm’s capability to flexibly and rapidly respond to environmental variations by assembling and (re)configuring requisite assets, knowledge, and business relationships [10]. On the other hand, information systems agility represents the ability of information systems development and deployment methods to swiftly adapt to the changing business requirements [1]. Drawing from these concepts, we conceptualize GDSD agility as the collective capability of globally distributed teams to rapidly develop and deploy systems by assembling globally distributed IT assets and expertise, in order to tap emerging business opportunities at dispersed geographic locations. To provide an understanding of the components of GDSD agility, we draw from the IT resource perspective [9]. Since organizational resources underlie organizational capability to respond [6], IT resources1 can be considered as crucial enablers of GDSD agility. We also draw from prior studies on agile software development, specifically in the OSS development context, to provide insights on the nature of each component of GDSD agility.
The OSS development context is characterized in terms of a highly distributed environment, cooperative and rapid development, and rapid evolution as the environment changes [5]. Similarly, in the highly distributed environment of GDSD, cooperation among globally dispersed teams, rapid systems development, and an IT infrastructure that is scalable and capable of evolving are crucial to the GDSD project. Based on these understandings, we identify three interdependent components of agility in the GDSD project context: agile IT strategy to suit changing business needs, agile IT infrastructure to enable the formulation and enactment of flexible IT strategies, and agile IT project management to enable coordination and control in the system development project. See Figure 1 for the three components of agility and their interdependent relationships, as depicted by the two-way arrows, in the GDSD project context.
Agile IT strategy. IT strategy defines the role of information systems in the organization, the business goals to be achieved through IT, the selection of IT standards and architecture, and the manner in which IT is deployed. First, need for an agile IT strategy has its basis in the requirements for an ongoing fit between IT and business strategy [7, 9]. Thus, agile IT strategies are grounded in agile business strategies responding to variations in the business conditions [4]. Since market needs and technology standards vary across locations and change over time, in the global business context the development of flexible IT strategies to meet specific local business needs becomes a critical issue.
Second, to make GDSD agile, firms must exercise loosely centralized control on their development processes. In OSS development, loosely centralized control provides high flexibility in fulfilling the customization needs for various situations [5]. Accordingly, a loosely centralized IT strategy for GDSD would enable firms to tap emergent local opportunities by facilitating flexibility in fulfilling local needs.
The third component of agile IT strategy—new IT resource exploration and exploitation—refers to innovative and fast implementations of business systems by deploying and utilizing new IT resources from external sources. New IT resource exploration and exploitation can enable GDSD teams to flexibly obtain and integrate emerging IT resources, thus enabling firms to capture emerging market opportunities.
Agile IT infrastructure. A firm’s IT infrastructure is defined by its IT platform and its IT applications [12]. Thus, two aspects of agile IT infrastructure can be conceived: an IT platform amenable to rapid development and deployment of localized business systems to support local business needs, and application support for agile communication and collaboration. With regard to the first aspect, a standardized IT platform can lead to fast reconfiguration and integration of IT resources [4, 9]. Moreover, loosely coupled applications, data, and other technology components in modular architecture enable firms to assemble modules locally customized to suit local needs while preserving global standards.
In OSS development, standardized IT platform and modular architecture particularly provide vital support for massive parallel development. Since each team (or individual) is engaged in developing specific parts, a standardized IT platform and modular architecture facilitates seamless integration of parts to build a whole system [11]. Therefore, customization and reuse capability based on standardized IT platform and modular architecture can enable agility in GDSD [8].
Regarding the second aspect, application software can streamline the system development process by providing IT-based communication and collaboration support [12]. In particular, Internet-based communication and collaboration tools are important components of OSS development in streamlining networking among distributed developers separated by location and time [1]. Likewise, tools such as videoconferencing and bulletin boards, are vital in GDSD projects by providing virtual space for communication and collaboration among distributed members.
Agile project management. We conceptualize four skill sets for agile project management in the GDSD context: system localization, task division and coordination, partnership management, and decentralized knowledge management skills. First, since globally distributed environments have local business and technology requirements, GDSD teams must adapt their IT resources across locations [8]. Therefore, management skills to clarify the extent of localization through an ongoing dialogue among various stakeholders are essential for agile project management.
Second, since GDSD members are globally distributed and/or culturally diversified, the skill to divide tasks and coordinate a highly diversified GDSD project team in terms of culture and expertise is critical for successful development and deployment. The agile methods in OSS development evoke the idea of coordinated development processes through the rational division of tasks that are voluntarily selected and developed by individuals or groups according to their interest and expertise [11]. Similarly, agile GDSD project management can be achieved through the rational division of tasks within member groups according to their local needs and expertise, and through the coordination of these divided tasks.
Third, partnership management with external partners, such as vendors, suppliers, and outsourcers, is another important component of a coordinated development process for GDSD [4]. Strategic partnerships with external partners can enable GDSD teams to coordinate better and quickly deploy new IT resources from external sources to achieve innovation, thus contributing to the rapid evolution of the IT infrastructure [12]. Fourth, knowledge management skill is another important skill in agile GDSD project management, because IT and business knowledge that resides across project teams is a strategic resource for global system deployment. Therefore, capturing, storing, transferring, sharing, and assimilating knowledge across locations is vital for capitalizing the distributed knowledge across diverse development teams for an ongoing development project [2].
Interdependence of the three components of GDSD agility. The three components mentioned here, though distinct, are highly interdependent [9]. According to Henderson and Venkatraman [7], organizational competitive advantage can be obtained through dynamic processes of strategic alignment between business strategy, IT strategy, organizational infrastructure and processes (in our case, project management), and IT infrastructure and processes. We believe these arguments are even more relevant to GDSD. For example, IT strategy to explore and exploit new technologies can lead to an agile IT infrastructure that enables firms to realize business strategies in innovative ways.
On the other hand, agility in organizational IT infrastructure is essential to the formulation of IT-enabled corporate and/or local business strategies. An agile IT infrastructure, specifically a standardized IT platform with modular architecture, contributes to the agility of project management by allowing fast and flexible integration of multiple system components. Furthermore, communication and collaboration support facilitates internal coordination and external partnership management through IT-enabled linkages [12]. Likewise, IS support for communication and collaboration enables knowledge sharing and assimilation in distributed groups [2, 10], thereby enabling agility in the formulation of IT strategy.
At the same time, relationships with external partners provide awareness and opportunities for exploring new technologies, thereby enabling the deployment of appropriate IT infrastructure to suit local needs. Thus, agile IT strategy development is heavily dependent on reciprocal understanding and collaboration between business and IT sides. Such cooperation also enables agile project management to solve unexpected problems during project execution. Thus, the three components of GDSD agility reinforce one another.
Skandia Financial Concepts: A Case Analysis
Established in 1855 and listed in the Stockholm Stock Exchange in 1863, Skandia is among the world’s top 20 life and casualty insurance companies. In late 1990s, Skandia, together with its technology partner, Tata Consultancy Services (TCS),2 identified two promising opportunities: a growing customer group, internationally mobile, with sizable financial assets and regular demand for managing its varied accounts and investments from international locations, and an emerging need expressed by small and medium-size regional banks and non-traditional actors (such as insurance companies, supermarkets, employee unions, and automobile associations) for providing Internet-based financial services to their customers. To capitalize on these opportunities, Skandia established a subsidiary, Skandia Financial Concepts (SFC),3 to develop, execute, and implement a novel business model with supporting organizational and IT strategies.
SFC’s business model was based upon the modularization of financial services and cooperation with external financial service providers. This business model allowed SFC to rapidly create a variety of new IT-enabled financial institutions in different countries for Skandia and its client organizations. It did so by a LEGO-like integration of predesigned, existing financial service components. This deployment was facilitated by agility in global project management fostered by a multi-layer4 modular IT infrastructure. Moreover, due to the variations in specific country requirements, such as language, currency, reporting and regulatory requirements, and specific business strategies for different channel preferences of customers, there was a strong need for country-specific localization of services.
In collaboration with TCS, SFC developed a comprehensive and flexible Internet-based financial services platform with a modular architecture to meet these needs. This platform was used as a basis for integrating a variety of software and service components sourced both from TCS and other third-party vendors of technology and IT-enabled services in Europe, the U.S., and India. These innovative organizational and technical architectures enabled Skandia to successfully develop and execute a novel business strategy with agility acquired from the interactive synergy of IT strategy, IT infrastructure, and project management.
SFC’s execution of business and IT strategy was in the nature of a truly globally distributed environment. To capitalize on the emerging business opportunities, SFC adopted an onsite-offshore delivery model that included a combination of onsite, offshore, and onsite-offshore development activities distributed in accordance with task characteristics. While user requirements and release management were primarily onsite activities, component coding and unit testing were sent to TCS’s software development sites in Delhi and Mumbai, India. On the other hand, interface design, integration of system components, and integration testing were done through the collaboration5 among client sites, SFC site (Zurich, Switzerland), and TCS sites.
Various service components were developed independently based on SFC’s requirements by third-party vendors at their own sites and later incorporated in SFC’s integration platform, that is, Apollo platform based on TCS’s Quartz banking engine. One such example was the development of Web site content and WAP interface by Mogul in Sweden. Collaborative development involving 16 vendors in globally distributed locations made it possible for SFC to develop its first bank, Skandia Bank Switzerland (SBS), within 20 months, its second bank, the Coop Bank in Sweden, within nine months, and its third bank, eQ Pankki OY in Finland, within just six months.
Interdependency of agile IT strategy and agile IT infrastructure. SFC’s IT strategy was to have a component-based, modular approach—a logical extension of Skandia’s business concept of collaborating with independent distributors and fund managers to deliver innovative, world-class financial services. The component-based IT strategy enabled the deployment of a novel IT infrastructure based on modular architecture to meet changing business needs. In turn, the availability and knowledge of the agile IT infrastructure that could support emergent business models facilitated the conception and execution of new business strategies to serve different types of banks in a short time.
While SFC was strategically created to tap emerging opportunities in global finance service, SFC was loosely bound with both Skandia and TCS as an organization that could independently cater to the IT needs of a variety of financial institutions offering different services. These included institutions that might traditionally be considered as Skandia’s competitors. The ongoing strategic sourcing partnership with TCS also enabled SFC to tap business opportunities in the finance solutions market and rapidly support it with the requisite IT infrastructure. In doing so, SFC assembled existing financial service modules available from TCS and other independent third-party financial services providers instead of developing a proprietary financial services platform from scratch.
Interdependency of agile IT infrastructure and agile IT project management. SFC’s standardized IT platform and modular architecture provided flexibility in developing localized financial services. Third-party service providers provided ready-made service modules for the platform and were also responsible for maintaining these services. This contributed to agility in project management by reducing development cycle time, since only those financial services that were not available from existing sources needed to be built by SFC. The main project management responsibility of SFC was the coordination of independent third-party services and the integration of these services within a SFC-developed financial service product. SFC’s agile IT infrastructure introduced considerable flexibility in the choice of standalone functional components and their reusability for such integration, thus further adding to agility in project management.
Not only did SFC’s agile IT infrastructure reduce the time from conception to market, it also provided the opportunity to localize the product to a particular market segment or customer at low adaptation costs. A product or service could be customized to a specific set of functional requirements by selecting and integrating appropriate service modules or customizing existing modules to the specific needs of the local context. Furthermore, SFC’s agile IT infrastructure was extensible as new service modules could be plugged into the platform as required.
Interdependency of agile IT strategy and agile IT project management. From its inception, SFC tried to select external vendors with the intention of building long-term sourcing relationships. These strategic relationships with external partners enabled SFC to maintain up-to-date knowledge on technologies. These relationships also enabled SFC to be more flexible in exploring new IT resources. New requirements to tap emergent business opportunities normally resulted in extensions to some components. By assigning a version number to each component and by recording change histories, SFC kept track of the various configurations deployed from multiple vendors. The ease with which the components were extended and managed in terms of version control through a configuration management strategy added to the agility in project management. Thus, component-based IT strategy aided agile project management.
The summarized analysis of the case with respect to the fit with the proposed framework and the specific lessons learned from the case are presented in Figure 2.
Conclusion
Through a framework that identifies the components of GDSD agility and describing their interactions, we have attempted to provide an understanding of agility in systems development and deployment in a globally distributed context. Our framework finds support from a case analysis of a global business group, SFC, which tapped opportunities in global finance service through an agile GDSD process. The generic guidelines that practitioners may draw from the study are presented in the accompanying table.
Our study serves to understand agility in a globally distributed work environment. Future research can aim at measuring agility with respect to the three identified IT components and tracing their causal paths through extensive study.
