The intended approach relies first on the identification of the main objectives and related important performance criteria. Then main threats can be identified and accordingly analyzed. In this context, concepts from the risk management field can become very useful. For example, Beasley et al. (2011) say about ERM that it provides the opportunity for organizational leaders to achieve a robust and holistic enterprise-wide view of potential risks that may affect the achievement of the organization’s objectives. As in ERM a building project is an organized and collaborative activity that aims at the achievement of a final product with regard to precise requirements expressed as performances. In view of that, a good overview of it risks is necessary to support design and investment decisions that minimize the probability of performance mismatches. In order to enable a holistic view and efficient control of risk, the concept of Key Risk Indicator (KRI) is introduced.

The process of scenario planning requires that an organization identify its current market context and likely future scenarios based on key risk drivers and their interdependencies. These future scenarios are then considered in relation to business objectives and planned transformation initiatives to understand how risk drivers might impact the extent to which the direction that an organization is taking will correspond to possible futures. This assessment can thus serve to identify the key risk drivers that threaten to steer a business environment toward less desirable futures. As such, it underscores the most important risk drivers on a strategic risk map and fosters the formulation of suitable Key Risk Indicators (KRIs) that can be used to monitor and predict those internal and external events that are most likely to threaten a business transformation.
Corporate Risk Management in Practice

Key Risk Indicators (KRIs) are those risk indicators which a particular organization’s management judges to be critical to its overall context. For example, out of an array of perhaps 20 areas of risk exposure identified by the organization as significant, the following in Table 2.1 might be judged to be KRIs:
Non-linear Hygrothermal Structural Analysis of the Elliptical Dome of the Church in the Universidad Laboral, Gijon, Spain

In this work, advanced numerical models determine the structural response of a masonry elliptical dome including the effect of moisture. The most important findings are the following: The complex geometry of the Church in the Universidad Laboral must be defined using a 3D parametric design model.MultiZone mesh method must be generated in the structural elements of the dome to obtain a regular tetrahedral mesh. In addition, the ribs must be divided into smaller parts to obtain a pure hexahedral mesh. The suitable element size for the geometry and dimensions of this work varies between 0.1 and 0.2 m.The temperature gradient due to thermal and moisture conditions in the masonry ribs significantly increases stresses and eventual crack defects. The stress levels are mainly due to the brick moisture expansion.The use of advanced numerical models including nonlinear contacts is suitable to study the hygrothermal and structural behavior of complex geometries and assemblies of different structural elements, such as ribs, columns, and annular rings.Constitutive material models are needed to efficiently model the performance of concrete and masonry bricks. In this case, William-Warnke and Drucker-Prager models were combined to obtain accurate results (Fuschi et al. 1994; Willam and Warnke 1975).The numerical results of the hygrothermal analysis show cracking patterns in the short masonry ribs and the elliptical central beam. These cracks can produce some deterioration in the elliptical dome.Tensile stress in the ring beams is close to the maximum admissible stress for reinforced concrete materials, about 4 MPa. However, the effect of moisture in the beams is remarkable being a key risk indicator of deterioration.
