The paper presents an explicit insight-based framework for the evaluation of dashboard visualisations and compares the performance of two groups of student engineering project managers against the framework: a group with the dashboard visualisations and a group without the dashboard. The results of our exploratory study demonstrate that student project managers who used the dashboard generated more useful information and exhibited more complex reasoning on the project progress, thus informing knowledge of the provision of information to engineers in support of their project understanding.

The questioning lens as research tool: the social shaping of network visualisation boundaries in the case of the U.K. junior doctors' contract dispute Social media and the data it produces lends itself to being visualised as a network. Individual Twitter users can be represented as nodes and retweeted by another Twitter user, thereby forming a relationship, an edge, between users. However, an unbounded network is a sprawling mass of nodes and edges. Boundary settings are typically applied, for example, a time period, a hashtag, a keyword search or a network substructure of a phenomenon of interest. Thus, the particular visualisation created is dependent upon the boundaries applied, enabling productive visual consumption, but concealing its social shaping. To explore this question of boundary setting and its associated issues, we draw on an example from the Twitter discussions about the U.K. Minister for Health, Jeremy Hunt and the media debate surrounding the contractual hours of junior doctors during 2015-2016. We discuss the role and impact differing stakeholders have in setting these boundaries. We seek to provide a set of 'questioning lenses' in which we ask why these boundary settings were selected, what effect they have, and what are the potential implications of these boundary setting techniques on the visualisation consumer.

Despite the target being the same for all acute hospitals, individual Trusts organise their services in different ways. The impact of this variation on patient journey time and waiting is unknown. Our study aimed to apply the Lean technique of Value Stream Mapping (VSM) to investigate care processes and delays in patient journeys at four contrasting hospitals. VSM timing data were collected for patients accessing acute care at four hospitals in South West England. Data were categorised according to waits and activities, which were compared across sites to identify variations in practice from the patient viewpoint. We included Public and Patient Involvement (PPI) to fully interpret our findings; observations and initial findings were considered in a PPI work...

First, we provide an introduction to network analysis and show how it can be applied to conversations between software ...

The concept is described generically as Remote Access Field Trip (RAFT). The interactivity framework proposed for assessing RAFT considers it within the context of live distance educa- tion and needs to be judged

However, studies on informal learning in this connection are still in their infancy. This article contributes to an emerging field of 'small data' research on Twitter by presenting a case study of how community managers in Finland used this social media platform to construct an informal learning environment around an annually organized conference. In this empirical study we explore informal learning behavior in project contexts especially by analyzing and visualizing informal learning behavior from Twitter data from conference participants.

Time is of the essence when patients' lives are at stake if they do not receive timely medical intervention. Healthcare service providers, managers and flow coordinators are particularly concerned with understanding where delays occur in the healthcare service they provide, in order that those delays are improved and patients receive the best possible treatment as quickly as they can. To understand delays a Lean improvement tool: Value Stream Mapping (VSM) has been applied to a NHS Emergency Department (ED) in the South West of England. This paper reports on the findings from that VSM research and particularly the use of the VSM visualisation. We highlight the issues of visualising patient waiting using the VSM approach and how this hugely important research area requires an improved VSM diagram to convey information to medical decision makers about patient delays.

Within the ethnographic mechanism there are various theories and affiliations that can be employed to research the practice of designing. This paper looks at three theories, activity theory (AT), grounded theory (GT) and ethnomethodology (EM). It will be proposed that an EM approach is an appropriate mechanism for understanding and analysing the earliest stages of product design.

This paper seeks to understand an undergraduate peer appraisal network from a final year design course. This paper considers go-between, vulnerable and core-member students and the implications that these roles have upon overall grade. It is hypothesised that go-between students are in a better position to gain appraisal from a broad range of student designers and are continually improving their work. In contrast vulnerable students are only refining their work with a limited number of their peers, whilst core-members are held within a set grade threshold. It is also proposed that go-between students are in a very influential position to impart their own subjective opinion about “good” design work to an entire design studio, which has important connotations on the success of the course as a whole.

Recent work in the field has exploited the opportunity afforded by Product Lifecycle Management systems, which capture the digital footprint of engineering projects to generate Design Structure Matrices in real-time through the co-occurrence of edits to product models. Given the systematic and more objective nature of the generation of these DSMs as well as being able to monitor their evolution throughout engineering projects, there now lies an opportunity in comparing projects/products using DSMs. To investigate this and the potential insights that could be generated, this paper presents the automatic generation of DSMs for two Formula Student projects. These have then been compared with respect to the end-of-project, change propagation characteristics and evolution of the DSMs. From this analysis, six insights have been generated that map the characteristics of the DSMs to the performance of the project/product and highlights the potential of automatic DSMs to further support engineering project management.
