Understanding the value of business process configuration

Noel Carroll , Eoin Whelan and Ita Richardson

Abstract


In order to deliver effective services, providers are being advised to `innovate' their service delivery systems. Innovation in this context often refers to technology, technique or restructuring improvements. However, the difficulty is that in the modern organisation, service delivery is dispersed across a complex network of numerous departments and units. There are greater pressures on organisational service systems to deliver a higher quality and more efficient service. Management must attempt to develop a greater understanding of organisational process and where improvements may be made using business process management (BPM). The network approach ultimately makes service innovations more difficult to implement. Thus, the purpose of this study is to investigate how service innovation is managed across a service network. Specifically, we examine the effectiveness of a technique called `social network analysis' (SNA) in extending business process management to enhance the manageability of network based services. This paper sets out to provide a state of the art literature review on the short fallings of our ability to understand what triggers business value. It examines the effects of our inability to understand the influence of business process behaviour on service innovation. It also provides a conceptual account of how SNA can be a powerful tool for managers to understand organisational network performance and service interaction (e.g. behavioural, functional, and structural). 153 The growth in service science as a discipline has underscored the need to investigate the contributory value of business processes and its influence on how a service system (including people, technology, and organisations) affects the delivery of organisational performance. Within organisational and technological management theory, understanding and measuring value (i.e. application of competences) of service networks is considered one of the key problems which prevent the sustainability of organisational growth. We refer to value as “the adaptability and survivability of the beneficiary system” [VMA08] (p. 148). Understanding the value of this infrastructure after investing often proves to be an even greater challenge [WSB02]. Therefore, assessing the value of the service processes is of critical importance. Service science explores the value cocreation of interactions between service systems (for example, [SM08], [VMA08]). As service networks continue to grow, understanding the dynamic exchange of resources which creates “value”, determined through specific relationships and interactivity between service systems is of significant importance. This paper sets out to provide a state of the art literature review on the short fallings of our ability to understand what triggers business value. It examines the effects of our inability to understand the influence of business process behaviour on service innovation. It also provides a conceptual account of how social network analysis (SNA) can be a powerful tool for managers to understand organisational network performance and service interaction (behavioural, functional, and structural). 2 Background to the Research Our traditional understandings of the `organisation', with solid boundaries and internally focused on operations, time, and individuality are becoming less apparent today. As competitive advantages of single organisational strategies continue to erode over recent years, organisations are experiencing greater demands to operate with increased innovation, collaboration, scalability, efficiency, agility, and virtuality (for example, [Z97], [MSB99], [RK02], [BH03], [AC05], [BM06], [F06], [K07], [VWVV07], [SMBG07], [C07], [G09], [H09]). In fact, services are now the dominant contributor to the developed economies. The business landscape has significantly changed, i.e. a shift from a goods-dominant logic towards a service-dominant logic ([N01], [VMA08]). It is evident that a scientific understanding of modern services is undeveloped and may even be described as an unexplored topic. This has sought the introduction of “service science” which attempts to address this problem. Service science is an attempt to “study the application of the resources of one or more systems for the benefit of another system in economic exchange” (p. 2) [SMBG07]. One of the fundamental objectives of service science is to understand the mechanics of service networks and define how and why they generate value. 154 [SMBG07] summarises one of the core problems in understanding the dynamics and complexity of service science: “powerful dynamics are in play around the world when it comes to applying resources effectively to solve problems and create value” (p. 10). Value (for example, economic, social, and interaction exchange) is the core of organisational sustainability. Over the past few years business practices have changed dramatically for several reasons including; globalisation, world financial crisis, accessibility of a global educated and mobile workforce, technological advances (`death of distance'), and global outsourcing. Understanding how these influences have distorted our understanding of business plays a significant part on how we interpret service networks. Many of these changes require that we view business with a new mindset to understand the interactions of global and electronic infrastructure which supports service operations. Transparency within service operations is envisioned as a critical factor within service innovation [CS06]. Organisations are under increased pressure to adapt their business processes at a much faster pace than they have ever experienced before [PBLDKL08]. Understanding the value of service network infrastructure after heavy investments often proves to be an even greater challenge. In addition, organisations must monitor what is often described as the `paper-based system' which is only too common through many organisational service systems. There is little evidence to suggest the organisations understand whether their service networks are operating at an optimum level and how can they demonstrate how value is created and measured. 3 Business Processes Defined The overall objective of implementing a business process is an attempt to improve business. Thus, we must understand the dimensions (for example, structural, behavioural, and functional) of the business process and its contribution towards organisational performance. The term `business process' has been well documented across literature in the hope to shape and reshape a more universally accepted meaning of the term. For example, [D93], (p.5) defines a business process as “$\dots a$ structured, measured set of activities designed to produce a specific output for a particular customer of market”. In addition, [HC93], (p.35) defines a business process as a: “$\cdots $collection of activities that takes one or more kinds of input and creates an output that is of value to the customer”. In more recent years, [SF03] define a business process as, “$\cdots $the complete, end-to-end, dynamically coordinated set of collaborative and transactional activities that deliver value to customers.” [SF03] dissect their definition, and extract the key characteristics of business processes. They specify eight characteristics of business process as follows: 1. Large and complex: involving the end-to-end flow of materials, information and business commitments. 2. Dynamic: responding to demands from customers and to changing market conditions. 3. Widely distributed and customised across boundaries: within and between organisations, often spanning multiple applications on disparate technology platforms. 155 “develop product” may run for months or even years. 5. Automated: at least in part. Routine or mundane activities are performed by computers whenever possible, for the sake of speed and reliability. 6. Both “business” and “technical” in nature: IT processes are a subset of business processes and provide support to larger processes involving both people and machines. 7. Dependent on and supportive of the intelligence and judgment of humans: the tasks that are too unstructured for a computer or require personal interaction with customers are performed by people. The information flowing through the automated systems can support people in solving problems and creating strategies to take advantage of market opportunities. 8. Difficult to make visible: these processes are often undocumented and embedded in the organization. Even if they are documented the definition is maintained independently of the systems that support them. The last characteristic is an interesting flaw within business process management (`difficult to make visible'). If we can understand the behaviour of business processes, surely we can offer a method to management to visualise the business processes behaviour and what influence (enables or inhibits) process innovation. After all, [P03], defines a business process as “a set of logically related tasks performed to achieve a well defined business outcome” (p. 49). In addition, [P07] explains that a business process comprises of a set of logically related tasks performed to achieve a well-defined business outcome that determines the results to be achieved, the context of the activities, the relationships between the activities, and the interactions with other processes and resources. Therefore, the behaviour exhibited within business process management, can provide us with a critical insight as to what influences organisational/service performance. Understanding this, relates back to how [CKO92] uses the term `business process reengineering', and defines it as `the redesign of an organisation's business processes to make them more efficient'. 4 Business Process Management As the current business practices are carried out, we know that taking a reactive stance in today's business environment is no longer sustainable. In addition, we must also look beyond the tangible assets within business processes. [A03], cautions that managers find it difficult to understand many of the critical intangible metrics of organisational networks (p.5): “Companies and economists struggle to develop new scorecards, metrics, and analytics that will provide leading indicators for how well a company or country is building capability for the future”. 156 Although Business Process Reengineering (BPR) was quickly embraced, organisations failed to reap its potential promise [H97]. One of our latest organisational theoretical developments is Business Process Management (BPM). BPM has adopted many definitions, however [DM97], report that no single solution exists to meet organisational performance needs. The value driven metrics of BPM therefore requires further attention. [LD98] (p. 217), offers a definition for BPM as: “$\dots a$ customer-focused approach to the systematic management, measurement and improvement of all company processes.” BPM is the latest development in extending our understanding of organisational management. BPM has emerged as one of the major new developments within organisations to support our understanding of the evolution and interaction of processoriented business applications and information systems. BPM has encapsulated many definitions over time, which identified the need to enhance a specific process or a number of processes, to allow an organisation to operate more efficiently. For example, [EHLB95], state that BPM consists of “$\cdots $systematic, structured approaches to analyse, improve, control, and manage processes with the aim of improving the quality of products and services.” The `value' of BPM was captured in the [LD98], case study as a method of “measuring the core processes, analysing what works and what doesn't and improving them” (p. 219). They also identify three critical factors which contribute to the success of BPM: (1) process discipline (correct and consistent application of business processes), (2) process improvement, and (3) cross-process integration. The concept of value-driven processes often refers to services within a business network that executes a business process to produce economic value while monitoring cost, quality and time parameters within business processes. Therefore, BPM should be considered as a tool with huge potential and not a fad of managerial toolsets [DM97]. However, according to [A03], one of the main problems of successfully managing organisations today is that it has become more complex due to the changing nature, structure and identity of organisations. One of the major emphases realised today in achieving a competitive advantage is in business intelligence (BI), through communicative and collaborative networks and knowledge management (KM) across the wider organisational spectrum ([D88], [D06], [EL05]. [WDLBNVP09], explore the use of Business Activity Monitoring (BAM) to map service choreography and monitoring agreements. To assist business analysts and managers to extract knowledge, there are often a number of BI tools available (e.g. IBM Cognos 8 is a single service-oriented architecture). However, these are limited in their functionality (i.e. ability to extract unstructured data and limited to focus on a single organisation rather than an entire network). While the current limited view is sufficient to address specific problems, a complete and holistic view of the BPM modelling space is required in order to avoid isolated solutions by providing an overall view over the whole organisational network [PBLDKL08]. This is more evident in the service-dominant logic business environment. 157 Organisational change, more specifically business process change is a critical activity across service networks to accommodate the reoccurring trends across the business landscape. However, change can take place on many dimensions, i.e. through continuous process improvements, or through radical rethinking a renewal of the business model and how business activity reflects this change. To look at BPM through a much broader lens, we revisit what [A04] suggests that BPM supports: “$\dots $business processes using methods, techniques, and software to design, enact, control, and analyse operational processes involving humans, organisations, applications, documents and other sources of information”. Therefore, the governance, chorography and management of human ad technological interaction are of critical importance to understand the competency of a service network. However, the literature indicates that there are several issues with our current understanding of BPM. For example, [PBLDKL08], state that BPM suffers from a lack of automation which `could' support the transition between the business domain and the information technology domain. We should also re-examine the goal of BPM as highlighted by [BCGMT05], the goal towards achieving business process automation, is motivated by numerous reason, including; creating opportunities in relation to cost savings and higher quality, more reliable executions, which has consequently generated the need for integrating the different enterprise applications involved in such processes. Within the [S08], BPM has received much attention. An extensive account of BPM describes a number of problems which are listed as follows: 1. Existing generation BPM technologies do not address quickly emerging requirements of complex, service enabled applications, involving several organisations. 2. BPM deployments are narrow in scope 3. Existing BPM adopt an organisation-centric view 4. Only provide improvements to business functions of a single organisation 5. Becomes a problem if managers are trying to apply existing methods to encompass agility to span service networks across organisational boundaries. In addition, existing methodologies or concepts (for example, BPEL) used within service engineering fail to capture and represent human aspects and other data including, the user goals, tasks, motivations and characteristics, and lacks information about the actors ability, actions, motivations. We wish to take this a step further and explain the need for more dynamic and explorative methodologies to understand the underlying behavioural patterns of service networks. 158 Information and communication technology (ICT) has been charged as one of the main contributors for organisational flattening [F06] and the evolvement of service science [CS06]. The wealth of information available on people and their roles, technology and processes, and organisations and activity has never been greater, nor has the prospect to (re)configure them into service relationships to create new value. The information revolution has given birth to new economies structured around processes and flows of data, information, knowledge, and more recently, people ([H89], [K89], [SG89], and [REMCV02]). Thus, information technology plays a significant role in the enabling or inhibiting of business process behaviour across service networks [WSB02]. To exasperate this, organisational boundaries have been redefined, creating larger `change' patterns [A03]. Despite all the attention however, the contributory value of services to organisations is still poorly understood. Considering the promise of BPM, understanding the value of service systems is prominent across several sectors of our economy. The concept of service science has become very popular throughout organisational and information systems literature. Service science is often referred to as a discipline which scientifically explores the theory and mechanisms required for the distribution of interoperable services. [SM08], state that “service science aims to explain and improve interactions in which multiple entities work together to achieve a win-win outcome or mutual benefits$\dots $.[as] value co-creation as a change or set of related changes that people prefer and realise a result of their communication, planning, or other purposeful and knowledge-intensive interactions”. This theoretical development is considered important to support today's dynamic and networked business world. However, considering that service science is a relatively new field, much of the literature attempts to understand the importance of service science and attempts to define what service science constitutes rather than prescribe precise methods to improve business practice. BPM could provide a significant contribution here with the emergence of a modern theoretical view of the business world (i.e. service science) and the application of business process technology (i.e. BPM). There has been a significant shift on the focus of a technological-centric view of business to a more holistic encompassment of business processes, human behaviour, and technology. 5.1 The Change in Business Landscape Technological advances are the main driving forces of service science especially across end-to-end electronic communication channels and service-oriented business models. This has afforded organisations the opportunity to break-up or to `unbundle' and the ability to put together or `rebundle' specific processes [N01]. Most notably, IKEA have become world class in their ability to unbundle their system of value creation or reallocate different economic actors, i.e. the customer now plays a significant role in 159 indentifying, transporting, and assembling IKEA furniture. Witnessing the dramatic change in business, it raises two core questions within service science and one in which this within BPM: what is the contributory value of business processes across a service network, and how do these contributions influence service innovation? As [F05] reports, “services have little value if others cannot discover, access, and make use of them” (p. 814). Thus, service science explores how an organisation conducts business and how we can optimise process influence on the delivery of a service. To gain a better understanding of how we might address these questions, we must first ask what constitutes as a service. Within the IS discipline, little research exists towards the exploration into the influence of ICT in service design and delivery, which suggest the need to revisit the modern concept of the `service'. In 1977, [H77] defines a service as: “a change in the condition of a person, or a good belonging to some economic entity, brought about as a result the activity of some other economic entity, with the approval of the first person or economic entity.” Economics typically attributes transactional value or market value to assets, good or service which is difficult to set by an individual economic actor [N01]. A market handles these complexities and establishes the market value which is determined by the buyer and seller. Within a service environment, a service may be viewed as the networked behaviour to offer a specific capability from one party to another through a predefined protocol or service compositions. Defined by [FF04], a service is a “$\dots $time-perishable, intangible experiences performed for a customer acting in the role of a co-producer.” Services are a fundamental factor in every organisation, for example, health care, education, retail, and finance. Services extend business processes and business functionality within (cross-departmental) and outside (cross-organisational) of an organisation. The behaviour in which it does so indicates the value of process within the service network. A service is often referred to as “protocols plus behaviour” [SMBG07]. Service activities include co-generated exchanges of largely intangible assets, collective coordination, and integration of knowledge under negotiated conditions between the provider and the supplier. According to [F05] “creating a service involves describing, in some conventional manner, the operations that the service supports; defining the protocol used to invoke those operations over the Internet; and operating a server to process information requests” (p. 814). The complexity of the service system or ondemand business architecture is often misunderstood which requires the introduction of new theoretical developments. Therefore, managers must begin to view services through a scientific lens to construct reusable and standardised modelling methods to evaluate and govern service networks and manage dynamic business process. 160 Through this new lens, we propose that service configuration is the core logic which should support service process management. Service configuration presents us with the ability to (re)construct reusable methods and process patterns or blueprints to support service networks through the visualisation of dynamic business process. The concept of service configurability has been well documented throughout business and information systems literature. For example, [N01] (p. 59) reports “a technological breakthrough in itself may be enough to trigger reconfiguration”, $\dots $[and] “creates cases of reconfiguration which seems to stem from a new design vision of the `industry' or broader system of value creation” (p. 61), e.g. IKEA, Apple, and Microsoft. Technology often serves to reconfigure business practice and processes albeit often without a strategic plan to reframe business practice to align with emerging business patterns. In addition, [N01] illustrates the dramatic shift in business logic from an assets dominant perspective to a reconfiguration of value-creating system as depicted in figure 1 below. Figure 1 above illustrates that significant towards a new strategic logic of the `economy of reconfiguration'. The main emphasis here is the competence to organise value creation extending beyond the traditional boundaries. This is largely due to the affordance of information technology and the virtual organisational infrastructures. Thus the “reconfiguration of value-creating systems” shifts our focus on the customer from being that of a recipient to being the co-producer and co-designer of value creation. These relationships between the service provider and client open up new possibilities on the generation of service innovation. Across academia and industry we are beginning to recognise the significance of service innovation and service systems within the global economy. One of the fundamental objectives of mapping these relationships is to understand the underlying mechanics of service networks and define how and why they generate value.

Organisations are beginning to move away from the traditional corporate hub of business practice towards a more diffused and distributed web of relationships and agile alliances. [N01]
