This paper conceptualises the development of a Patient Information Management system to assist health care professionals and carers in providing an enhanced level of support to patients. By focusing on throughput analysis and mission criticality the system designers can make valued judgement on the needs of the professional and system's long term requirements.

As the Internet is transforming the global information economy, the Telecollaboration (TC) system services are moving at a transitional pace dictated by market forces. However, the pace is turning out to be a lot slower than expected. This has prompted us now to approximate and synthesize the design concepts of building a scalable biomimetic system manager for a telecollaboration service taxonomy. Thus, it is expected that if there is more correlation across the design concepts of the system manager, the greater will be the likelihood of demonstrating a rescue-like operation for humans in this new taxonomy. The main goal of this paper is initially to over view the bio-swarm behaviours of insect colonies to embrace a notional computing architecture that enables an individual TC service entity. It is important that these behaviours along with the proposed self-x autonomic functions offered by the system manager need to be pursued, and indeed continue, in a highly correlated way to fulfil the opportunistic functional tasks related to the discovery and delivery of Telecollaboration services. In this context next, we attempt to study the significant usability benefits of qualitative and quantitative execution pressures related to the implementation of these functions. This includes a better understanding of the constraints of implementation of these functions to deal with complex usability performance baselines. Finally, we give an updated foresight of process deployment strategies through a group of highly diverse and autonomous objects called Teleholons whilst exploiting the role of these self-x autonomic functions.

This paper proposes the emerging Telecollaboration (TC) business system environments supported by Video over IP applications, thus contributing the measurement of user experience. Initially, a simple but comprehensive analytical model for Video over IP is presented for the development of Quality of Service (QoS) indices. We then characterize the model with few illustrative units that provide an integrated context for estimation and mapping of the quality and quantity measures of Video over IP in the ubiquitous Internet. This includes application of Pittsâs software methodology, whilst addressing the second-order network performance statistics in the context of jitter (such as delay and packet-loss variation). Finally at the network level, the behavior of source, queuing, multi-service requirement mechanisms and a set of flows, connections and aggregates are measured to justify the quality inherent usability aspects of video quality. It is expected that the proposed modeling overcomes the degradation of video quality, which is seen as a fundamental problem that often occurs due to the multi-user packet switched network. Our results also suggest that the experimentally validated analytical modeling of Video over IP is of considerable value in promoting the TC initiatives.

Lack of high-level usability awareness often leads the e-business communities to a missing relative assessment of capability of collaborative businesses effectively in terms of achieving strategic and competitive advantages. In this paper, we propose a new strategic framework for an evolutionary Collaborative Space of Opportunities (CSO) whilst using a Telecollaboration (TC) business system during Enterprise Resource Planning (EPP) training. Initially, we apply Callos's General System Theory (GST) with the description of logistics elements of this framework. Next, we provide a business logistics management perspective within CSO, addressing organizational effectiveness, technology integration control efficiency and user satisfaction. This includes formation of co-evolutionary loops to induce the apparent system usability objectives to explore the emergence of business logistics portfolios and technology integration control profiles of the users. We then describe our proposed Collaborative Space of Opportunities Matrices (CSOM) to analyse the apparent usability alternatives in this multi-criteria decision making environment. In this context, we apply the general form of Saaty's Analytic Hierarchy Process (AHP) to demonstrate how these matrices could be used as a generic elicitation tool. It is here, we provide a set of systematic, explicit, rigorous and robust reinforcement mechanisms for quantifying and prioritizing the Decision elements (De) involved. We assume that the exposition on AHP has the Business process Re-engineering (BPR) effect to measure and synthesize the often conflicting apparent usability objectives and alternatives of a TC business system during EPP training.

The telecollaboration (TC) business system is an important class of emerging applications that is spawning new challenges in achieving the desired levels of performance. One important implication in identifying and characterizing the properties of TC system implementations is that performance evaluation should no longer be isolated and viewed as a separate analytic activity. Instead, we require a physical and logical understanding of the complex quality issues that affect overall performance of applications, systems and network infrastructures. As one of the natural artifacts of this practice, a workload model are developed to characterize a TC system. We demonstrate how such an analysis may result in characterization of workload behavior, and that in turn lead to definition of efficient analytical model parameters, network invariants and use of relevant quality metrics. The study of underlying issues of telecollaboration quality of service (TQoS) within the context of TC could have positive impacts on performance analysis and traffic control, if the analytical modeling used remains consistent and effective in describing the Web-based environments.
