How the methodology can be a success factor?

Thanks for the invitation.

I fully agree with Ms. Ghada Eweda's answer. Don't feel any need to increase.

Thanks for invitation....I endorse answers given by colleagues &Experts

Based on Klaus G. Grunert  and Charlotte Ellegaard, 1992 The Concept of Key Success Factors: Theory and Method.

Definitely, a methodology can be a success factors in different ways:

 1- as a necessary ingredient in a management information system, b) as a unique characteristic of a company,

2-as a heuristic tool for managers to sharpen their thinking,

3- as a description of the major skills and resources required to be successful in a given market. We adopt the last view.

In marketing domain, The actual key success factors on a market, and those key success factors perceived by decision-makers in companies operating in the market, will be different. A number of psychological mechanisms result in misperceptions of the causes of success on a market. Both the actual key success factors on a market, and the way they are perceived by decision-makers, are amenable to scientific analysis. Such an analysis can improve performance of decision makers on that market.

However, the major immediate causes of success on any market are the value perceived by customers in a business's products, and the costs (relative to competitors) incurred in producing this value. How good a business is in creating customer value at low costs will depend on skills and resources of the company. We therefore define a key success factor as a skill or resource that a business can invest in, which, on the market the business is operating on, explains a major part of the observable differences in perceived value and/or relative costs.

On the other hand,  Key success factors differ from core skills and resources, which are prerequisites for being on a market, but do not explain differences in value created and costs incurred. They also differ from slack skills and resources, which neither explain differences in value created and costs incurred, nor do they form prerequisites for being on a market.

Therefore, Key success factors differ in their changeability, e.g. in the degree to which competitors can emulate them. They also differ in whether they are conjunctive or compensatory. Conjunctive key success factors are necessary conditions for superior performance. Compensatory key success factors open up for choices of areas of excellence and hence for the formation of strategic groups.

Accordingly, Methodologies are  useful in perceiving key success factors which can be measured by semi-structured interviews with business decision-makers which follow a laddering procedure. Actual key success factors can be measured by collecting objective or semi-objective company data and relating them statistically to measures of relative costs and perceived value.

It is one of the main factor of project management. So, ofourse it would be sucess factor for any projects or  busiensses. 

I leave the answer to the experts. Thanks for the invitation. .
