Author in this article has make following assumptions:-

Author has used Duncan's empirical finding method in this article. As per author, he has chosen this instrument because It was simple and seemed to distill structural concepts from many other instruments. Now, as per our understanding this assumption is valid because by this, he is trying to overcome statement made by Schoonhoven regarding the lack of mathematical deficiency in this model. By this method, he has tried to prove his hypothesis quantatively.

Author has used the measure of fit in this article with matches with the definition provided by Schoonhoven and with general congruency model. As per author, this measure is very simple and easy to apply. Here, this model assumes that for each value of a technology variable there is a best value of structure in terms of high performance.Here, Author has explicitly mentioned this assumption. It is valid in this article because this measure should only be used when two variables are highly correlated and here, technology and structure is highly correlated and this measure also ensures that the reliability of the model on the whole. So, the output that we are getting by this does not possess any thread to this article.
