The designing a strategic plan is the same in which the source of the external forces is referred to PEST and Porter’s five forces. And also the source of internal strength is referred to Resources, HR, Management, Financing, Marketing and so on. In fact, if we are very clever to arrange the external forces where we will be able to secure the stability of our company, the lack of internal strength will push our company to be collapsed due to the external forces (all external forces will be changed to the threats).
What is the difference? The difference is assigned to the sources of external and internal forces in which the forces on the beam are unique but the forces in strategic management are inferred from many sources. In fact, in strategic management, the independent variables are more than engineering. Therefore, to design a strategic plan is very harder than designing in the field of engineering. For instance, if we consider that a beam has been made by different types of materials, the analysis of stress – strain on the beam will be the complex and very hard.
