    Developing and presenting a mathematical model for the purpose of organizational culture architecture based on creating alignment between the strategic reference points of organiza... by Elyas hasanzadeh Shweili, Mir Mehrdad peidaie, Ali reza Rezghi Rostami

    Published 2024-05-01
    “…Strategic reference points of organizational elements Strategic reference points are points for coordination that, if all elements and systems of the organization coordinate with it, an all-round coordination will occur (Kiyajori & Brimani, 2017). The method of strategic reference points, which is also called alignment, has a key position in organizational studies and strategic management; because a suitable method for acquiring and creating value in the market and increasing the performance of the organization is the interaction and coordination between the elements and components of the organization and the environment (Walian et al, 2017). …”
