What is Risk?
Every human endeavour or action
involves risk. In our daily life, one faces a variety of situations involving
many unknown, unexpected, frequently undesirable and often unpredictable
factors. These factors can be conveniently compiled under the category of risk
(Hertz and Thomas, 1983). Custom software development companies in India have
started giving importance to risk management and consider an important aspect
of project management.
Risks in Construction Industry
Construction risks are generally
perceived as events that influence project objectives of cost, quality and time.
Some of the risks associated with the construction process are fairly predictable
or readily identifiable; others may be totally unforeseen. Al-Bahar (1990)
provides different categories of risks often encountered in construction
projects are shown in Figure 1.
Figure 1. Types of risks in the
construction industry (Al-Bahar, 1990)
Risk Management in Construction
Risk management may be defined as a
process to control the level of risk and to mitigate its effects and impacts on
overall project. It is a systematic and well-structured approach for
identifying, evaluating and responding to risks encountered and identified in a
project (Nummedal et al., 1996). In Figure 2, the risk management life cycle is
shown. If maintained, this cycle yields a controlled risk environment (Baker et
al., 1997).
In project management terms, the
most serious effects or impacts of risk can be summarized as follows:
·
Cost deviations
·
Project timeline deviation
·
Quality deviation
The purpose of risk analysis and
management is to help stakeholders to avoid these failures
(Thompson and Perry, 1992).
Process Management Process
Risk analysis helps in estimating
potential impacts of risk and in making decisions regarding which risks to
retain and which risks to transfer to other parties. Below is a systematic
6-steps approach of risk analysis proposed by Flanagan and Norman (1993).
STEP 1 - All the various options should be
considered
STEP 2 - Consider the risk attitude of the
decision-maker
STEP 3 - Consider what risks have been
identified, which are controllable and what the impact is likely to be
STEP 4 - Measurement, quantitative and
qualitative
STEP 5 - Interpretation of the results of the
analysis and development of a strategy to deal with the risk
STEP 6 - Decide what risks to retain and what
risks to allocate to other parties
Case Study
A construction project is selected to
understand what kind of risks are encountered during the project development
life cycle. Following risk management register explains complete risk
management cycle that was used in this project. It also helps to understand how
risks are managed and controlled during the project life cycle.

Conclusion
No Construction Project is Risk free. Risk can be managed, minimized,
shared, transferred or accepted. It cannot be ignored. Risk management is an
integral part of project management and it helps to achieve project objectives
and targets. There are some limitations
of risk management. If Risks are improperly assessed or
prioritized, time can be wasted in managing risks. Spending too much time
assessing and managing unlikely risks can divert focus of resources to
unnecessary things. Unlikely events do occur, it may be better to simply retain
the risk and deal with the result if the loss does in fact occur. Software companies in India consider risk management as an integral part of project development life cycle and gives due importance to ensure timely, qualitative and within budget project delivery.
