Crowd Sourcing Literature Review

Literature Review

(Pedersen et al., 2013) [1] suggested that crowd-sourcing is a collaborative model that gives an open call for externals to solve difficult problems. Businesses and other entities are turning to crowd-sourcing to obtain external skills, to access collective intelligence and creativities from the virtual crowd, and to decrease costs. They proposed a conceptual model for organizing the crowd-sourcing. The conceptual model resembles the traditional Input-Process-Output (IPO) model. The elements of conceptual model are: Problem, Process, Governance, Technology, and peoples, and Outcome. The problem is the heart of the crowd-sourcing and is the statement for starting and desired ending condition. Process is a set of actions that

To understand and simulate crowd-sourcing platform they suggested a model called ABM that had four components Requester, Workers, Task and Environment. They described a process to build this model. ABM use properties of workers, task and design experiments to study a system. Amazon Mechanical Turk (AMT) is chosen as a crowd-sourcing system to build an ABM. AMT is a crowd-sourcing Internet marketplace that enables individuals or businesses to coordinate the use of human intelligence to achieve tasks that are hard to process by computers. in this paper they designed Human Intelligence Task (HITs) on AMT to show workers a parking lot video and ask the viewers to record when a car enters/exits the parking lot. Verification and Validation are used to evaluate this model. Verification checks the correctness and consistency by unit and integration testing. Validation checks accuracy of the model by Genetic

CrowdREquire is a platform to develop requirements for projects submitted by individuals, corporations or any other external bodies. Requirement engineering involves different stages like elicitation, analysis, specification and quality assurance. CrowdREquire use two approaches: business model and market strategy. The CrowdREquire business approach is detailed viewing the purpose, goals, stakeholders, work context model and typical business events of CrowdREquire. The market strategy involves using appropriate strategies and corresponding methods for connecting with the customers. Some of the factors considered in CrowdREquire market strategy are market segmentation strategy, targeting strategy, positioning strategy, corporate message and image, product and service strategy, pricing strategy, distribution. channels, promotion and advertising strategy, sales strategy and sales forecasts. CrowdREquire have some challenges such as Quality Assurance (QA), government and legal issues, and business viability. These challenges are tackled by using some methods like client-defined tests, modularization of tasks, two-sided platform model. One area of further research is to execute a cost assessment model for CrowdREquire in order to better understand its direct financial
