The traditional method used often is net present value method(NPV)for valuing project. NPV is useful in many cases, but it doesn't get to the heart of how intimately linked capital allocation is to long term corporate strategy. In general,past investment projects generate future as well as current opportunities-an important consideration that NPV rarely takes into account. This paper presents an advanced valuation techniques-the real options approach that remedies some of the deficiencies inherent in traditional NPV. The main emphasis will be on techniques that emphasize the role that the adoption of projects plays in the overall long term strategy of a corporation. Because in reality the future markets have the great uncertainty that produces risky or opportunity with project so as to change the value of project. This will have an effect on decision making. The real options approach recognize that financial market information can be useful for determining the expected cash flows of a project as well as the appropriate discount rate and can thus provide more accurate estimates of value. Base on this, how to use the real options approach is introduced. The role that the real options approach played in valuing the project with abandonment or defer or extend etc. strategic options is described with examples.
