▼ Small businesses, which are defined by the US Small Business Administration as entities with less than 500 employees, suffer interruptions from diverse risks such as financial events, legal situations, or severe storms exemplified by Hurricane Sandy. Proper preparations can help lessen the length of the interruption and put employees and owners back to work. Large corporations generally have large budgets available for planning, business continuity, and disaster recovery. Small businesses must decide which risks are the most important and how best to mitigate those risks using minimal resources.
This research uses a series of surveys followed by mathematical modeling to help discover risk factors, mitigating actions, and the highest return scenarios as a basis for a low-cost business continuity/disaster recovery plan. The surveys use a Delphi study format in order to rank a base list of risks and mitigating actions and to supplement those lists with ones added by the participants. Survey results are analyzed and presented back to the group for a second round of ranking and supplementing the risk/action categories. After two rounds of surveys the data is presented to an expert panel to investigate how the risks interrelate. Quantifying the interrelationships is the basis for the Cross Impact Analysis model that is able to show the relative impact of one event upon another. Once the impacts are known, a series of high valued scenarios are developed using Interpretive Structural Modeling. These high valued scenarios can be used by the small businesses as a basis for a business continuity/disaster recovery plan.

Effects of information importance and distribution on information exchange in team decision making.
Degree: PhD, Information Systems, 2012, New Jersey Institute of Technology

▼ Teams in organizations are strategically built with members from domains and experiences so that a wider range of information and options can be pooled. This strategic team structure is based on the assumption that when team members share the information they have, the team as a whole can access a larger pool of information than any one member acting alone, potentially enabling them to make better decisions. However, studies have shown that teams, unlike individuals, sometimes do not effectively share and use the unique information available to them, leading to poorer decisions. Research on information sharing in team decision making has widely focused on the exchange of shared or unshared information in the hidden profile paradigm, neglecting the role of information importance. Informational influence theory holds that the importance of information may affect how information is processed for making decisions in teams.
This study investigates information exchange processes to understand how teams can effectively exchange and use information available to them to make better decisions. The specific research question concerns the extent to which importance and distribution of information is associated with its exchange during discussion in distributed teams. Data are collected in a laboratory study involving subjects interacting with a computer-mediated decision support system.
The results show that the importance of information, the distribution and the interaction of importance and distribution have significant main effects on information exchange. Teams tend to exchange a higher proportion of the more important information compared to the less important information. A third dimension is introduced to measure information distribution – partially shared information – and is found to have a strong main effect on information exchange. It is also found that the extent to which team members exchange more important information during discussion strongly correlates with the tendency to improve team performance. It is also found that task complexity is negatively correlated with information exchange performance. Teams tend to exchange a smaller proportion of information when working on complex tasks, compared to when working on simple tasks.
This dissertation makes contributions in three areas. Firstly, a theoretical model is developed that allows for the investigation of the joint relationship of the importance of information and its distribution in team decision-making. Secondly, this work introduces a
new approach to investigate information sharing, exchange and use in decision-making teams. Others can apply this approach fruitfully in investigating similar phenomena outside of the current domain. Finally, this work improves the understanding of information sharing and exchange processes in relation to the distribution of information and its importance.

▼ This dissertation researchdesigned, implemented, and evaluated a Web-based Dynamic Voting Toolfor small group decision-making in a collaborative environment.
In this dissertation, theliterature on voting tools in current GDSS research is presented. Variousvoting theories and methods are analyzed, and the advantages and weaknessesare compared, so as to gain a better understanding of how to apply thesedifferent voting methods to diverse decision-making situations. A briefoverview of scaling theories is also given, with an emphasis on Thurstone'sLaw.
The basic features of someweb-based voting tool implementations are reviewed along with a discussionof the pros and cons of Intemet voting. A discussion of Human DynamicVoting (HDV) follows; HDV allows multiple voting and continuous feedbackin a group process. The Dynamic Voting Tool designed and developed bythe author (i.e., Zheng Li) integrated multiple scaling and voting methods,and supported dynamic voting. Its features, user feedback, and futureimprovements are further discussed.
A controlled experiment wasconducted to evaluate the effects of the Dynamic Voting Tool (alongwith the List Gathering Tool by Yuanqiong Wang) interacting with smallgroup process. The design and procedures of the experiment, and thedata analysis results extracted from 187 student subjects from
New JerseyInstitute of
Technology are reported. While the System Survey yieldedvery positive feedback on the voting tool, the hypotheses tested bythe Post-Questionnaire and expert judgments showed no major positivesignificant results. This was probably due to the complexity of thetask and procedures, lack of motivation of the subjects, bad timing,insufficient training, and uneven distribution of subjects, etc.
Several field studies usingthe Social Decision Support System (SDSS) Toolkit (List Gathering Tool+ Dynamic Voting Tool) are presented. The SDSS system worked well whenthe subjects were motivated. The field studies show that the toolkitcan be used in course evaluations, or other practical applications.
Finally, it is suggestedthat future research can focus on improving the voting tool with truedynamic features, exploring more issues on SDSS systems design and experimentation,and exploring the relationship of voting and GSS.

▼ This research focuses on how to build a "list" structure to combine individual items of information into some sort of structure that converts the individual items of information into a structure of knowledge relative to the problem. Software was designed to provide relationships among and comparisons of the contributions in a "list" structure, so that individual members of a group process will be able to understand the contributions of information made by the group as a whole.
A List Gathering Tool was designed and implemented, which is one component in a Web-based Social Decision Support System (SDSS) Toolkit. Then, a two-by-two factorial design (list tool support vs. no list tool support, and voting tool support vs. no voting tool support, respectively) controlled experiment and several field studies were carried out to assess the effects of this List Gathering Tool in a group problem solving process.
Overall, the evaluation results are encouraging. The utilization of the List Gathering Tool or the SDSS Toolkit does tend to improve the ability to discover valid alternatives. An additional set of field trials illustrated how the SDSS Toolkit can be utilized in a collaborative learning environment to improve teaching and students' learning experience. This system will also work for very practical applications in large group settings.

▼ SMS text-messaging is an interoperable communication vehicle known to be dependable for mass media alert notifications in crisis management. SMS text-messaging also offers potential as one viable two-way communication alternative for field responders in crisis response. Both continuously changing mobile information communication technologies and the importance of precise information exchange constitute a need for communication protocol training and practice. This study introduces a
technology-mediated training technique based on speech act and communicative action theories. These theories are used to inform the design of a baseline measure for task performance improvement and to suggest a model to predict communication readiness. Because this research bridges two fields - information systems and communication - it provides a model for full construct-representation of text-based interaction in a
technology-mediated environment. The proposed model is validated through a web-based training application with
50 participants who have different crisis response backgrounds, including emergency management practitioners, first responders, public safety volunteers, community volunteers, community citizens, and students over the age of 18. Each group encompasses diverse technological skill and usage levels.
The web-based training application developed in the present study features plain language training so that a clear understanding of user behavior, response, and training would emerge. The training and crisis scenario are rendered through multimedia recordings and designed to measure task response, based on the 160 character per SMS text-message exchange limit. The mixed-methods design begins with a crisis scenario, followed by pre-training measures, three repeated training measures, and concludes with post-training measures. A total of six tasks are introduced (3 pre-training and 3 post-training) in which each participant interfaces with the web-based training application through a high-speed Internet connection. Task response level results show promise for this exploratory research and contribute to a
new discourse mode that extends to mobile
technology penetration. Future research will focus on refinement of the model's task performance measures and will seek to introduce additional situation-based scenarios and mixed-modes of communication. During this next research phase, the objective is to incorporate the model into mobile device usage and operationalize the model in authentic crisis management contexts. If successful in extended field simulation, the model may have the potential to ensure effective mobile information communication within the context of crisis.

▼ Chief Information Officers (CIOs) lead enterprise information
technology organizations (EITOs) in today's dynamic competitive business environment. CIOs deal with external and internal environmental changes, changing internal customer needs, and rapidly changing
technology.
New models for the organization include flexibility and suggest that CIOs should create and manage an enterprise IT organization that is more flexible in order to manage change and prepare for uncertainty, but they do not define what is meant by flexibility.
The first objective of this exploratory and ethnographic research study was to understand how uncertainty and unexpected change are currently managed by CIOs. The second was to develop a systematic definition of enterprise IT organizational flexibility, The third was to explore the potential value of a proposed 'enterprise IT organizational flexibility framework' to be used by CIOs to better manage uncertainty and unexpected change. Rich research data was collected in an exploratory ethnographic study from in-depth interviews with twenty CIOs. These participants included a diverse representation from large to small enterprises, different industries, and with a variety of IT education and functional enterprise experiences.
The conclusions from this study included a clearer understanding of the CIO's leadership role when managing uncertainty and unexpected change, a definition of enterprise IT organizational flexibility with three aspects: anticipation, agility, and adaptability, and a framework for enterprise IT organizational flexibility assessment and development.

▼ The improvement of Internet
technology has motivated distributed work groups to collaborate without meeting face to face. Although asynchronous meetings through Web-based group communications systems enable groups dispersed temporarily and geographically to collaborate more flexibly, parallel and non-linear communication among dispersed members also challenge effective and efficient group coordination. Moreover, the Web-based asynchronous meeting is distinguished not only from the face-to-face meeting but also from the synchronous computer-supported meeting in terms of coordination process. However, previous asynchronous group communications or virtual team research focused more on the comparison of this
new type of meeting with the face-to-face meeting. Not many research efforts have been exerted to improve the productivity of this
new form of meeting and find ways to overcome its disadvantages. Facilitation was proved effective to enhance the productivity of synchronous meetings. However the effect of structured discussion through facilitation was not clear in asynchronous meeting settings even though facilitation is a common practice in asynchronous group communication systems.
This study examined the effect of a facilitated structure in improving the productivity of asynchronous decision-making groups. Delphi was chosen as the facilitated structure because it has been widely used as the paper-and-pencil-based structure to facilitate dispersed experts in collecting their opinions. In this study a computer-based Delphi structure was implemented through asynchronous Computer-Mediated Communication. A 2X2 controlled experiment was conducted to investigate the effect of Delphi structure on the effectiveness of small-sized (5-6 members) and medium-sized (10-12 members) asynchronous computer-supported groups. The formal facilitation using Delphi structure was effective to improve the productivity of asynchronous groups in generating more ideas. On the contrary, informal leadership by group coordinators seems to have played a more important role in producing better reports. In terms of per person ideas, small-sized groups were more productive, even though medium-sized groups produced more total ideas than small-sized groups. The superiority of Delphi groups and small-sized groups is related to their higher equality of participation. This result suggests that in asynchronous meetings, equal participation of group members in discussion is important in improving idea generation productivity while in synchronous meetings, the process loss of production blocking plays a crucial role.

▼ Data Definition Languages (DDLs) have been created and used to represent data in programming languages and in database dictionaries. This representation includes descriptions in the form of data fields and relations in the form of a hierarchy, with the common exception of relational databases where relations are flat. Network computing created an environment that enables relatively easy and inexpensive exchange of data. What followed was the creation of
new DDLs claiming better support for automatic data integration. It is uncertain from the literature if any real progress has been made toward achieving an ideal state or limit condition of automatic data integration. This research asserts that difficulties in accomplishing integration are indicative of socio-cultural systems in general and are caused by some measurable attributes common in DDLs. This research’s main contributions are: (1) a theory of data integration requirements to fully support automatic data integration from autonomous heterogeneous data sources; (2) the identification of measurable related abstract attributes (Variety, Tension, and Entropy); (3) the development of tools to measure them. The research uses a multi-theoretic lens to define and articulate these attributes and their measurements. The proposed theory is founded on the Law of Requisite Variety, Information Theory, Complex Adaptive Systems (CAS) theory, Sowa’s Meaning Preservation framework and Zipf distributions of words and meanings. Using the theory, the attributes, and their measures, this research proposes a framework for objectively evaluating the suitability of any data definition language with respect to degrees of automatic data integration.
This research uses thirteen data structures constructed with various DDLs from the 1960's to date. No DDL examined (and therefore no DDL similar to those examined) is designed to satisfy the law of requisite variety. No DDL examined is designed to support CAS evolutionary processes that could result in fully automated integration of heterogeneous data sources. There is no significant difference in measures of Variety, Tension, and Entropy among DDLs investigated in this research. A direction to overcome the common limitations discovered in this research is suggested and tested by proposing GlossoMote, a theoretical mathematically sound description language that satisfies the data integration theory requirements. The DDL, named GlossoMote, is not merely a
new syntax, it is a drastic departure from existing DDL constructs. The feasibility of the approach is demonstrated with a small scale experiment and evaluated using the proposed assessment framework and other means. The promising results require additional research to evaluate GlossoMote’s approach commercial use potential.

▼ This dissertation investigated the impact of cultural differences in temporal perception on globally dispersed software development teams. Literature and anecdotal evidence suggest that these temporal differences affect individual communication quality, which in turn will affect individual satisfaction and trust within global teams. Additionally, the temporal dispersion of the team was expected to affect an individual's sense of temporal disruption which, in turn, was expected to affect individual satisfaction and trust. Differences in temporal perception were expected to moderate this impact on perceived temporal disruption. A Fortune 100 Company that carried out software testing in Ireland, the United States, China and India provided the respondent population which resulted in all testing teams having global membership.
The research used two methods for data collection: survey and interviews. The survey instrument's constructs were developed via pilot tests conducted on student software development teams and through a card sorting task. Four temporal perception constructs were used: Future Orientation, Lateness Attitude, Temporal Rigidity and Temporal Urgency. Team members answered the temporal perception questions twice; once for how they felt their remote team members would answer the questions and once for how they felt their local team members would answer the questions. A gap analysis was performed on this data yielding temporal perception difference scores. A Gap Magnitude that looked at the size of the gaps was also calculated to provide measures of the size of
the cultural differences. Semi-structured interviews were carried out on fifteen percent of the respondent population to explore the temporal perception differences in more detail. Survey results only partially supported the hypotheses that cultural differences in temporal perceptions affect Individual Communication Quality. Specifically, it was found that group differences in the temporal perceptions of Sense of Urgency and Lateness Attitude significantly impacted Individual Communication Quality. Sense of Urgency also impacted Individual Trust. Follow-up interviews suggested that differences were recognized, but other factors such as an orientation to a future benefit by working hard now, the prestige of working with people in the Company's home country and possibly a sense of being a professional, may have outweighed the examined temporal differences. It also was found that Temporal Distance affected an individual's Temporal Disruption, that Individual Communication Quality affected Individual Trust, and Individual Satisfaction.
Gap Magnitude helped identify areas of potential problems that corresponded to areas identified by management, and mentioned by the employees in their interviews. Overall, the research suggests that certain Temporal Perceptions affect Individual Communication Quality, which in turn affects Trust and Individual Satisfaction. Communication, itself, seemed to be a large cause of problems, in part,…

▼ Organizations have moved from a face-to-face team environment to a virtual team environment using communication
technology during the last decade. More and more workers use asynchronous tools (including email, discussion groups, information sharing tools, and group calendaring systems), and synchronous tools, such as instant messaging and web-based chatting features, to coordinate and share information with people within and outside of organizations. This empirical study on how virtual teams work, integrating mobile devices with web-based group communication for decision-making tasks, examines which technologies and communication modes are the best for distributed group teamwork, and, mainly, what are the predictive characteristics making mobile group communication successful. This thesis includes research motivations and research questions, followed by a theoretical framework based on existing theories and an extensive literature review, methodology, and data analysis. The last part is the results with conclusions and contributions of this study.
Further work should focus on dispersed virtual teamwork using different communication modes and technologies depending on the characteristics of the tasks and members, and organizational cultures.

▼ Virtual teams are an important work structure in global software development. The distributed team structure enables access to a diverse set of expertise which is often not available in one location, to a cheaper labor force, and to a potentially accelerated development process that uses a twenty-four hour work structure.
Many software teams are partially distributed, that is, part of the team is colocated. Such partially distributed global software teams are an important work structure in software development projects. However, little is known about what affects or improves team members’ motivation and job satisfaction in the partially distributed environment. This study investigates the effects of leader delegation to sub-teams and trust between sub-teams on global software team members’ motivation and job satisfaction. It proposes a research framework based on specific hypotheses regarding these effects. A survey instrument was created and a pilot study conducted on student project teams in two U.S. universities. In addition, a study combining interviews and a survey distribution using industry software development teams was also conducted. The studies found that team competence predicts leader delegation to a sub-team in global software projects. Leader delegation related to teamwork process improves team members’ motivation and satisfaction with the leader. However, leader delegation may also generate negative consequences for the sub-teams, such as anxiety and pressure. Cultural distance and geographical distance impair trust development between members across sub-teams. Temporal distance causes conflicts related to excessive overtime and meeting scheduling. Trust in sub-teams is critical to improving motivation in a global software project. In addition, this study explores the impacts of language differences and software engineering profession culture on global software team members’ interactions. Suggestions are proposed for how to shape delegation strategies in partially distributed global software projects and how to improve team members’ trust in each other and their motivation. This work provides important findings for organizations interested in developing leadership skills for global software teams and retaining IT professionals at distributed sites.
