Development of a risk assessment tool for post-project appraisal

Anaç, Caner
As competition in the business environment increases, knowledge management becomes a critical success factor. Firms should be able to gather, analyze and reuse knowledge to support their strategic decisions. Construction firms should also analyze information in hand (completed and on going project data) and make it a part of their learning mechanism. Post-project appraisal is an organizational learning mechanism aiming to form an organizational memory. Organizational memory is a remedy for organizational amnesia, which is a very common problem in the construction industry due to the project-specific nature of the industry and lack of systematic ways to manage knowledge. Particularly, information about risks and their consequences is an important piece of knowledge that the firms should refer to in the forthcoming projects in order not to do the same mistakes. v Risk management comprises of risk identification, analysis and formulation of risk response strategy to maintain an optimum risk-return structure in a project. It is agreed upon by many researchers that, although risk management is accepted as one of the critical success factors for construction projects, project participants generally do not have sufficient knowledge pertinent to risk management concept and the number of tools which facilitate the risk management process is rather low. Typically, companies carry out a risk assessment exercise at the start of a project and the obtained risk ratings are used to determine contingency. However, after the project is over, a final assessment is not usually carried out. The main idea in this study is that, in order to improve the risk assessment process in forthcoming projects, risk assessment should be a part of post-project appraisal. Risk events that actually happened may be classified according to their sources and impacts (monetary/nonmonetary) as well as the effectiveness of utilized response strategies. Consequently, companies may learn from what had happened in previous projects and prepare more realistic risk management plans in the future. The major objective of this thesis is to develop a project risk management information model for risk assessment using historical data in order to improve risk assessment process in forthcoming projects. The framework is modeled to ensure information continuity throughout the project life cycle by storing and reusing project information that resides in risk event databases. The applicability of the developed database system is tested on a real construction project and potential benefits are discussed.


Developing a roadmap for knowledge management in construction industry
Erkan, Ceyhun Selim; Nielsen, Yasemin; Department of Civil Engineering (2007)
High turnover rate of employees in construction cause companies in the sector struggle against knowledge loss. Due to the high competition in the market, companies differentiate by keeping and increasing their intellectual capital generally acknowledged as the main source of competitive advantage. Knowledge Management (KM) is defined as any process or practice of creating, acquiring, capturing, sharing, and using knowledge, wherever it resides, to increase learning and performance by sustaining organisation...
Identifying the effects of education, activities and skills of information technology (it) senior managers and their impact to the organization in the private sector
Ekimci, Namık Atila; Özkan Yıldırım, Sevgi; Department of Information Systems (2009)
Information Technology (IT) is considered as a very important part of today’s world of business and researches indicate that it helped and still helps companies to lower their costs and increase the information quality with speed. On the other hand, Senior IT Managers, such as Chief Information Officers (CIO) roles are very important in the IT department more than other department’s relationships with their senior managers. This study investigates the identification of the effects and importance of the acti...
Critical success factors for partnering in the turkish construction industry
Eren, Köksal; Köksal, Eren; Department of Civil Engineering (2007)
Partnering is in the agenda of many construction companies worldwide as it is an effective strategy that may increase competitiveness of partner companies and reduce risks retained by each party. In order for partnering to reach its expected benefits, partner selection is of vital importance. Similarly, there are some critical success factors (CSF) that should be taken into account by the parties in order to maintain a successful partnership throughout its lifecycle. The aim of this thesis is identification...

Tuncer, Şeniz; Erdil, Erkan; Department of Science and Technology Policy Studies (2004)
In this study, Project Management, especially Project Communication Management applications and use of information technology are scrutinized. The general situation of Turkish electronic sector is investigated. The project management applications and closeness to new technologies of companies that operates in Turkish electronic sector are analyzed. A research model is developed with a designed questionnaire, and the levels of project communication management applications and use of interactive communication...
Cost estimation of housing projects by functional areas
Öncül, Mustafa; Arıkan, Metin S.; Department of Civil Engineering (2006)
Good conceptual cost estimates is one of the most important factors affecting the project success. Investment decisions taken and budget preparations are performed from the results of the conceptual estimates. Also, the most difficult cost estimation is the early estimates where there is very limited information. This thesis provides a model for the cost estimation of the housing projects at the conceptual stage, considering not only the total area of the construction, but also considering fractional areas,...
