Application of a risk visualization framework using semantic risk data to empower risk communication

Ertaymaz, Muzaffer Uğurcan
Risk communication is one of the major factors that effects the success of a project. Conventional risk management focuses on risk checklists and matrices, and considerable amount of risk information is discarded and not communicated. Without communicating the necessary risk information, risk management strategies cannot be applied effectively. The purpose of this study is to develop a systematic and practical risk visualization framework that shall improve the risk communication strategies. The proposed framework is the demonstration of practical applications in construction sector as the communicated information depends on many different factors that can vary between companies. The demonstration of application of such framework starting with determination of nine commonly used types of risk- related semantic data from the literature. After determination of those types, the risk visualization methods that exists in the literature are identified and the selected types of data are integrated to those methods by considering visualization design guidelines. In order to demonstrate the iterative manner of development of risk visualizations that enhances risk communication, a workshop is prepared, and six sector practitioners are invited. The workshop consists two stages, pre- and post-presentation of visualizations. Participants are asked to rate the necessity of selected types of risk-related semantic data and the prepared risk visualizations in terms of four different aspects through a survey. In the end, the importance and value of risk visualization has been verified via the workshop and according to participant comments, visualizations are revisited, and necessary revisions are made.


A risk management approach for acquisition of software intensive systems in the Turkish Army.
Saylan, Necip; Demirös, Elif; Demirös, Onur; Department of Information Systems (2002)
The current techniques of risk assessment rely on checklists and human expertise. This constitutes a rigorous approach only when the people are experts on risk assessment. This thesis introduces a formal method and addresses the necessity of the identification and analysis of the risk. During implementation of risk management process, risk assessment will be discussed within an acquisition of software intensive systems in the Turkish Army. This thesis includes a survey and comparison of other software risk ...
Project Cost Benefit and Risk Analysis using Bayesian Networks
Yet, Barbaros; Fenton, Norman; Neil, Martin; Luedeling, Eike; Shepherd, Keith (null; 2015-07-16)
Uncertainty and risks are common elements of all major projects. Yet such uncertainty is rarely effectively calculated when analysing project costs and benefits. This paper presents a Bayesian network (BN) modelling framework to calculate the costs, benefits, and return on investment of a project over a specified time period, allowing for changing circumstances and trade-offs. The framework uses hybrid and dynamic BNs containing both discrete and continuous variables over multiple time stages. The BN calcul...
A critical review of risk management support tools
Dikmen Toker, İrem; Birgönül, Mustafa Talat (null; 2004-09-03)
It has been claimed by many researchers that "a risk driven approach" to project management is necessary to increase the success of construction projects. Literature is very rich in conceptual frameworks to overcome the informality of risk management efforts. However, risk management paradigms exist as methodologies rather than systems which can fully support the risk management process. The existing risk management support tools are usually based on quantitative risk analysis whereas the other phases are c...
Identifying and managing risk in mega-projects: the case of automotive test center project in Turkey
Ayvazoğlu, Buğra; Akın Ateş, Melek.; Department of Business Administration (2019)
The issue of risk assessment in projects has attracted considerable attention in both practice and the literature. Although the number of studies investigating large-scale engineering projects (construction, rail system projects, power plants, etc.) has been increasing, majority of them focus on private sector. In this thesis, it is specifically focused on a current, mega-project where both governmental and private organizations participate, namely the Automotive Test Center Project carried out in Turkey. T...
Measuring risk tolerance in finance: Does the decision frame matter?
Özdemir, Özlem (2013-06-01)
Risk taking behavior has great influence on the decision making process of individuals. In this respect, the methodology used in assessing individuals’ risk tolerance becomes an important issue. However, there is lack of unique and commonly used risk tolerance measure in literature. There are mainly two different approaches in measuring risk tolerance in literature; lottery versus financial risk assessment technique (FRT). The purpose of this study is to investigate whether measurement techniques differ wi...
