Diverse businesses, such as garbage collection, retail banking, and management consulting are often tied together under the heading of “services”, based on little more than a perception that they intangible do not manufacture anything. Such definitions inadequately identify managerial operational implications common among, unique to, services. We present “Unified Services Theory” (UST) to clearly delineate service processes from non‐service key commonalities across seemingly disparate...
Abstract The management of new service development (NSD) has become an important competitive concern in many industries. However, NSD remains among the least studied and understood topics literature. As a result, our current understanding critical resources activities to develop services is inadequate given NSD’s importance as competitiveness driver. Until recently, generally accepted principle behind was that “new happen” rather than occurring through formal processes. Recent efforts...
Services and products possess various attributes, some being more important than others. Importance-Performance Analysis (IPA) is a technique for prioritising attributes based on measurements of performance importance. A weakness IPA that it conceptualises attribute importance as scalar which independent performance. In this article we theorise not adequately represented point estimate, but function When changes, does also, can change the relative priority subsequent improvement efforts....
Abstract Supply chains are quite easy to define for manufacturing organizations where each participant in the chain receives inputs from a set of suppliers, processes those inputs, and delivers them distinct customers. With service organizations, one primary suppliers process is customers themselves, who provide their bodies, minds, belongings, or information as processes. We refer this concept being "customer‐supplier duality." The duality implies that supply bidirectional, which production...
Service operations management (SOM) has a rich history of important but not widely recognized contributions to research and practice. There also seems be some uncertainty about how SOM fits in the broader fields service management. This article addresses those concerns by introducing visual framework called Process-Chain-Network (PCN) Analysis. The is built upon PCN Diagrams that depict processes interactions involving networks entities. Analysis includes identifying value proposition given...
This article conceptualizes service supply chains according to the Unified Service Theory, which defines services as bidirectional that have customers both providing resources and receiving from providers. We establish how eight traditional roles in manufacturing are assumed by chains. Those service–customer include component supplier, labor, design engineer, production manager, product, quality assurance, inventory, competitor. describe these manifested business‐to‐consumer...
Abstract The impact of business operations on the natural environment has been a public concern for decades and research years. To date, focus environmental almost exclusively manufacturing industries. Environmental specific to service industries have neglected, despite fact that economies developed nations are mostly made up businesses. This paper explores potential distinctions businesses as they may influence management motivation taking environmentally friendly actions. Through number...
A small electromagnetic sampling calorimeter, installed in the ZEUS experiment 1995, significantly enhanced acceptance for very low x and Q^2 inelastic neutral current scattering, e^{+}p \to e^{+}X, at HERA. measurement of proton structure function F_2 total virtual photon-proton (\gamma^*p) cross-section is presented 0.11 \le Q^{2} 0.65 GeV^2 2 \times 10^{-6} 6 10^{-5}, corresponding to a range \gamma^{*}p c.m. energy 100 W 230 GeV. Comparisons with various models are also presented.
Professional service jobs exist at the high end of skill ladder; thus, some have assumed that highly trained professional workers are relatively immune to being replaced by automation. However, this assumption is a bit dubious because automation does not occur job level but rather task level, and tasks within might be susceptible disruption. This research builds on prior (1) empirically testing model for services (2) developing task-automation framework shows how individual given can...

Abstract Labor is a crucial resource in most organizations. In not‐for‐profit, public, and government services, it common for labor to include unpaid volunteers. This article demonstrates how the volunteer assignment (VLA) problem markedly different from traditional (TLA) problems such as scheduling. One core difference pertains cost structure of labor, where TLA seek minimize costs, yet costs volunteers are usually trivial. Another assumed size pool: typically assumes sufficient cover task...
In this article we address the problem of scheduling a single project network with both precedence and resource constraints through use local search technique. We choose solution definition which guarantees feasibility, allowing procedure to focus on overcoming infeasibility. 110-problem data set Patterson test our procedure. Our results indicate significant improvement over best heuristic reported date for these problems (Bell Han [1]). Two major advantages algorithm are its ability handle...
Abstract No society works exactly like its constitution, and no organization functions according to official administrative guidelines. In the life of all societies bureaucratic organizations — East West there exist a whole variety "informal structures" by which people accomplish their delegated tasks or through they achieve own personal goals. West, we speak such informal structures in terms "networks" "connections." Those who "know somebody" can go around queue obtain free goods services...
It is common for service providers to collect data from customers as part of efforts monitor quality. Often, this passively collected, meaning (a) any solicitation feedback done without direct customer interaction, and (b) the initiates response given. Examples include comment cards, toll‐free telephone numbers, links on World Wide Web pages. This article compares passive collection with active methods (e.g., interviews mail surveys). Passive generally have lower rates are inherently biased,...
Abstract Customer queues resemble inventories of goods in that they both incur costs waiting. However, the immediate customer are primarily psychological, with subsequent being dissatisfaction and reduced future sales. A fundamental element psychological waiting is wait‐perception bias, which propensity to overestimate (or underestimate) passage time spent In 1985, Maister proposed a number principles affect bias [Maister, D., 1985. The psychology lines. In: Czepiel, J., Solomon, M.,...
There are two manifestations of supply chains in health care. One involves the equipment and materials used care delivery. The other chain delivery itself, wherein patients their physical conditions service suppliers deliver services. This article considers latter chain, analyzing a case study which have comorbidities thus require services network multiple providers. In study, we examine three schemes for coordination first scheme, patient herself is expected to manage coordination. second...
Purpose The customer contact approach to service has been at the core of theory since 1970s. It suggests that potential operating efficiency a is inversely related extent with provider's operations and various design issues are dictated by presence or absence contact. purpose this article reevaluate in light advanced digital technologies. Design/methodology/approach authors review origins history show ways it refined research literature. From they demonstrate how can be applied contemporary...
Abstract Digital technology has enabled significant productivity gains in many industries. Manufacturers have benefited from robotics, and service businesses self‐service technologies. An area that seen only meager is professional services, such as healthcare, consulting, legal higher education. Despite the emergence of artificial intelligence (AI) other new technologies, services continue to be labor intensive with high costs. In 2021, Sampson published an empirically‐based framework...
This article introduces the Special Topic Forum (STF) on Service Supply Chains (SSC). A fundamental purpose of STF is to more clearly define field SSC research and provide conceptual foundations, as well empirical observations. review literature shows three perspectives that correspond source‐make‐deliver processes from well‐known supply chain operations reference (SCOR) model. The contains articles assume each perspectives: sourcing services, making services involved in product delivery....
