“…Schall [74] describes the Human-Provided Services framework, which applies the principles of service-oriented architecture to the discovery, composition, and selection of scalable human workforce. Vaculin et al [85] propose a WaaS protocol and meta-model aimed to enable decomposition, delegation, adjustable management, control, and visibility of how the work is coordinated and performed. However, as noted by [75,41], there is a potential danger in treating workers as an "API call".…”

Integrating crowd-based systems to organizations is highly complex. A major of source of this complexity stems from the nature of organizational work design. Work design and configurations of work performance, in the traditional organizational model, are tightly woven into the structure and functions of organizations, whereas crowdwork leverages an undefined network of people without an organized managerial or hierarchical model. This paper examines work design theories in organizational studies with a view to exploring their potential for addressing the fundamental challenges of work design in organizational crowdwork. Drawing on review of extant literature on crowdwork and analysis of perspectives in work design theories, the paper outlines ways in which crowdsourcing research, on one hand, can interpret and utilize work design theories, and on the other, contribute to redesigning work design theories to keep pace with the important and rapid transformation of work from the traditional staffing paradigm to crowd and open models.

“…Work-as-a-service formalizes various operations such as merge, tear, pause, and resume which allow the control actions we will need to develop the RHC algorithms [24]- [26]. We do not go into details of the work-as-aservice algebra in this paper, but focus on the larger optimized coordination enabled by it.…”

Formal coordination mechanisms are of growing importance as human-based service delivery becomes more globalized and informal mechanisms are no longer effective. Further it is becoming apparent that business environments, communication among distributed teams, and work performance are all subject to endogenous and exogenous uncertainty.This paper describes a stochastic model of service requests in global service delivery and then puts forth a cognitive approach for coordination in the face of uncertainty, based on a perception-action loop and receding horizon control. Optimization algorithms used are a mix of myopic dynamic programming and constraint-based programming. The coordination approach described has been deployed by a globally integrated enterprise in a very large-scale global delivery system and has been demonstrated to improve work efficiency by 10 − −15% as compared to manual planning.

“…A closely related work is [41], which develops a formal framework for several algebraic operations on GSM schemas, including the notion of "tear" which is similar to splitting. However, the work of [41] does not address runtime problems and the race conditions solved here. Also somewhat related are artifact-centric interoperation hubs [21], which enable multiple parties to collaborate on a single artifact-based business process (state-machine-based or GSM) that is maintained by the centralized hub using an underlying centralized GSM engine.…”

Case Management is emerging as an important paradigm for Business Process Management. The Guard-Stage-Milestone (GSM) model is a recent case management approach that substantially influences OMG's emerging Case Management Modeling Notation standard. We study the problem of outsourcing part of a GSM schema to another party, and develop a formal framework that supports splitting and outsourcing of GSM schemas. One element of the framework focuses on restructuring the GSM schema to facilitate outsourcing while preserving the semantics of the original schema; the second focuses on locking protocols that define how the distributed parties should operate. Additionally, the framework allows parties to keep local parts of their GSM subschema private without affecting the outcomes of the global execution. The rules restructuring developed here enables a crisp separation of concerns, which allows reuse of existing GSM (and thus Case Management) engines for executing the subschemas. Both elements of the framework are formally proven correct.
