A main conclusion of this dissertation is that the Design School of Strategic Planning is a viable method for performing strategic planning with respect to mission statement construction leading to financial performance. In addition, internal dimensions in writing mission statements are associated with higher firm performance than external dimensions in the writing of mission statements. This dissertation research determined that firms should have both a vision and mission statement as it was determined that these are (or should be) two separate documents. This research revealed specific characteristics and components of these documents that are critically important for inclusion as per their association with organizational performance. From, Part II of this dissertation, a robust new method for performing SWOT Analysis by identifying five characteristics of each factor of AQCD is proposed. This process should help provide further evidence that the Design School of strategic planning is a viable option for firms globally. Additionally, Part II provides a foundation for improving both strategic planning in practice and strategic management research going forward.
