Beside developing strategies, success of organizations depends on alignment of strategies. One of the important functional areas in which companies develop strategies is operation. Alignment of operation strategies is called horizontal alignment. The aim of this article is to present a model for alignment of operation strategies. To this end, an original algorithm has been presented by which horizontal alignment of operation strategies in food and chemical (detergents) industries have been analyzed. . In order to develop the alignment model, descriptive-survey and correlation methods were used. Data for this research have been studied with regard to alignment by using data mining methods and Clementine software. The results indicated that alignment affects performance. Proper alignments in the aforementioned industries were identified and appropriate guidelines were recommended to companies.
