Despite the evolution of purchasing operations over many years, a comprehensive perspective
is lacking in practice, leading to inefficiencies. This study aims to validate a model
designed to guide how to balance the purchasing environment. It comprehensively delineates
the general pattern (a map) of real-life purchasing procedures and standardizes these
elements to provide clarity and coherence. The model's novelty lies in the thoughtful
selection and arrangement of factors, and their classification into two groups forces
and drivers. This facilitates a structured approach to analyzing purchasing status
through a checklist. By mapping purchasing activities, the model connects issues to
its factors. After identifying existing weaknesses in operations by this linkage among
the model's elements and problems, the framework serves as a valuable diagnostic tool
supporting managerial decisions and enhancing efficiency. The validation study comprised
case studies and survey research conducted at five multinational companies, involving
over 130 purchasing professionals. Research proved the model's validity in terms of
correctness, completeness, and applicability.
